Bernard can use the equation h = (220 - (3.5 * 40))/40 to predict how many hours they will drive in the afternoon.

In this equation, h represents the number of hours they will drive in the afternoon, 220 is the total distance to the park, 3.5 is the duration of the morning drive in hours, and 40 is the average speed in miles per hour.

In the first paragraph, we summarize that Bernard can use the equation h = (220 - (3.5 * 40))/40 to predict the number of hours they will drive in the afternoon. This equation takes into account the total distance to the park, the duration of the morning drive, and the average speed. In the second paragraph, we explain the components of the equation. The numerator, (220 - (3.5 * 40)), represents the remaining distance to be covered after the morning drive, which is 220 miles minus the distance covered in the morning (3.5 hours * 40 miles per hour). The denominator, 40, represents the average speed at which they expect to drive. By dividing the remaining distance by the average speed, Bernard can calculate the number of hours they will drive in the afternoon to complete the trip to the Gold Coast State Park.

The total number of calculators produced during this period is approximately 14,850.

To find the number of calculators produced from the beginning to the end of the fifth week, we need to integrate the rate of production equation with respect to time. The given rate of production equation is dx/dt = 5000 (1 - 100/(t + 10)^2), where t represents the number of weeks.

Integrating the equation over the time interval from 0 to 5 weeks, we get:

∫(dx/dt) dt = ∫[5000 (1 - 100/(t + 10)^2)] dt

Evaluating the integral, we have:

∫(dx/dt) dt = 5000 [t - 100 * (1/(t + 10))] evaluated from 0 to 5

Substituting the upper and lower limits into the equation, we obtain:

[5000 * (5 - 100 * (1/(5 + 10)))] - [5000 * (0 - 100 * (1/(0 + 10)))]

= 5000 * (5 - 100 * (1/15)) - 5000 * (0 - 100 * (1/10))

≈ 14,850

Therefore, the number of calculators produced from the beginning to the end of the fifth week is approximately 14,850.

To find the value of F(14,1) for the double integral with reversed order of integration and limits of integration (0 to 0.6), we need to express the integral in terms of the new order of integration.

The given integral is:

∬(0 to 0.6) f(x) dxdy

When we reverse the order of integration, the limits of integration also change. In this case, the limits of integration for y would be from 0 to 0.6, and the limits of integration for x would depend on the function f(x).

The first statement claims that the series Σ (8")(10")(7")(9") + 1 is not convergent. To determine the convergence of a series, we need to analyze the behavior of its terms.

In this case, the individual terms of the series do not approach zero as n tends to infinity. Since the terms of the series do not approach zero, the series fails the necessary condition for convergence, and thus, the statement is True. The second statement states that the series Σ (-1)-1 n+n²+n³ is convergent. To determine the convergence of this series, we need to examine the behavior of its terms. As n increases, the terms of the series grow without bound since the exponent of n becomes larger with each term. This indicates that the terms do not approach zero, which is a necessary condition for convergence. Therefore, the series fails the necessary condition for convergence, and the statement is False.

The choice function C defined on the subsets of X does not satisfy the Weak Axiom of Revealed Preferences (WA).

The Weak Axiom of Revealed Preferences states that if a choice set B is available and a subset A of B is chosen, then any larger set C containing A should also be chosen. In other words, if A is preferred over B, then any set containing A should also be preferred over any set containing B. In the given choice function C, we can observe a violation of the Weak Axiom of Revealed Preferences. Specifically, consider the subsets {a, b} and {a, c}. According to the definition of C, C({a, b}) = C({a, c}) = {a}. However, the subset {a, b} is not preferred over the subset {a, c}, since both subsets contain the element 'a' and the additional element 'b' in {a, b} does not make it preferred over {a, c}. This violates the Weak Axiom of Revealed Preferences.

The parametric equation of the line L is given by x = 1 + t, y = 2 - t, z = 1 + t (where t is the parameter).

Given curve C :{y² + x²z = z + 4 xz² + y² = 5}Passes through the point (1,2,1).

As it passes through (1,2,1) it satisfies the equation of the curve C.

Substituting the values of (x,y,z) in the curve equation: y² + x²z=z + 4 xz² + y² = 5

we get:

4 + 4 + 4 = 5

We can see that the above equation is not satisfied for (1,2,1) which implies that (1,2,1) is not a point of the curve.

So, the tangent to the curve at (1,2,1) passes through the point (1,2,1) and is parallel to the direction vector of the curve at (1,2,1).

Let the direction vector of the curve at (1,2,1) be represented as L.

Then the direction ratios of L are given by the coefficients of i, j and k in the equation of the tangent plane at (1,2,1).

Let the equation of the tangent plane be given by:

z - 1 = f1(x, y) (x - 1) + f2(x, y) (y - 2)

On substituting the coordinates of the point (1,2,1) in the above equation we get:

f1(x, y) + 2f2(x, y) = 0

Clearly, f2(x, y) = 1 is a solution.Substituting in the equation of the tangent plane we get:

z - 1 = (x - 1) + (y - 2)Or, x - y + z = 2

Now, the direction ratios of L are given by the coefficients of i, j and k in the equation of the tangent plane.

They are 1, -1 and 1 respectively.So the parametric equation of the line L is given by:

x = 1 + t, y = 2 - t, z = 1 + t (where t is the parameter).

To find the points where the line L intersects the surface z² = x + y.

Substituting the equations of x and y in the equation of the surface we get:

(1 + t)² = (1 + t) + (2 - t)Or, t² + t - 1 = 0

Solving the above quadratic equation, we get t = (-1 + √5)/2 or t = (-1 - √5)/2

On substituting the values of t we get the points where the line L intersects the surface z² = x + y.

They are given by:

(-1 + √5)/2 + 1, (2 - √5)/2 - 1, (-1 + √5)/2 + 1)

Let L be the straight line that passes through (1, 2, 1) and has as its direction vector the vector tangent to curve C = {y² + x²z = z + 4 xz² + y² = 5} at the same point (1, 2, 1). The parametric equation of the line L is given by x = 1 + t, y = 2 - t, z = 1 + t (where t is the parameter). To find the points where the line L intersects the surface z² = x + y, the equations of x and y should be substituted in the equation of the surface and solve the quadratic equation t² + t - 1 = 0.

a. The point estimate for the population proportion is approximately 0.097.

b. The function we use is the confidence interval for a proportion:

CI = p ± z * √(p(1 - p) / n)

c. The 98% confidence interval for the proportion of pneumonia patients who are under the age of 18 is approximately 0.0765 to 0.1175.

d. Increasing the level of confidence (e.g., from 90% to 95% or 95% to 98%) will result in a wider confidence interval.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

a. To find a point estimate for the population proportion of all pneumonia patients who are under the age of 18, we divide the number of patients under 18 (145) by the total number of patients in the sample (1500):

Point estimate = Number of patients under 18 / Total number of patients

              = 145 / 1500

              ≈ 0.0967 (rounded to two decimal places)

So, the point estimate for the population proportion is approximately 0.097.

b. To construct a confidence interval for the proportion of all pneumonia patients who are under the age of 18, we can use the normal distribution since the sample size is large enough. The function we use is the confidence interval for a proportion:

CI = p ± z * √(p(1 - p) / n)

Where p is the sample proportion, z is the z-score corresponding to the desired confidence level, and n is the sample size.

c. To construct a 98% confidence interval, we need to find the z-score corresponding to a 98% confidence level. Since it is a two-tailed test, we divide the remaining confidence (100% - 98% = 2%) by 2 to get 1% on each tail. The z-score corresponding to a 1% tail is approximately 2.33 (obtained from the standard normal distribution table or a calculator).

Using the point estimate (0.097), the sample size (1500), and the z-score (2.33), we can calculate the confidence interval:

CI = 0.097 ± 2.33 * √(0.097 * (1 - 0.097) / 1500)

Calculating the values within the square root:

√(0.097 * (1 - 0.097) / 1500) ≈ 0.0081

Now substituting the values into the confidence interval formula:

CI = 0.097 ± 2.33 * 0.0081

Calculating the upper and lower limits of the confidence interval:

Lower limit = 0.097 - 2.33 * 0.0081 ≈ 0.0765 (rounded to two decimal places)

Upper limit = 0.097 + 2.33 * 0.0081 ≈ 0.1175 (rounded to two decimal places)

Therefore, the 98% confidence interval for the proportion of pneumonia patients who are under the age of 18 is approximately 0.0765 to 0.1175.

d. Increasing the level of confidence (e.g., from 90% to 95% or 95% to 98%) will result in a wider confidence interval. This is because a higher confidence level requires a larger margin of error to capture a larger proportion of the population. As the confidence level increases, the z-score associated with the desired level also increases, leading to a larger multiplier in the confidence interval formula. Consequently, the width of the confidence interval increases, reflecting greater uncertainty or a broader range of possible values for the population parameter.

The given prompt involves composing three functions, f(x), g(x), and h(x), and  the value of (f ◦ g ◦ h)(0) is 2√2.

To find (f ◦ g ◦ h)(0), we need to evaluate the composition of the three functions at x = 0. The composition (f ◦ g ◦ h)(x) represents the result of applying h(x), then g(x), and finally f(x) in that order.

Let's break down the steps:

First, apply h(x): Since h(x) = 2, regardless of the value of x, h(0) = 2.

Next, apply g(x) to the result of h(x): Since g(x) = [tex]x^2[/tex], g(h(0)) = g(2) = [tex]2^2[/tex]= 4.

Finally, apply f(x) to the result of g(x): Since f(x) = √(2x), f(g(h(0))) = f(4) = √(2 * 4) = √8 = 2√2.

Therefore, (f ◦ g ◦ h)(0) = 2√2.

For the expression (f ◦ g ◦ h)(x), the same steps are followed, but instead of evaluating at x = 0, the value will depend on the specific value of x given. The expression (f ◦ g ◦ h)(x) represents the composed function for any value of x.

To find the dimensions of the rectangle that would maximize the enclosed area, we can use the concept of optimization.

Let's assume the length of the rectangle is x cm. Since we have a piece of wire 60 cm long, the remaining length of the wire will be used for the width of the rectangle, which we can denote as (60 - 2x) cm.

The formula for the area of a rectangle is given by A = length × width. In this case, the area is given by A = x × (60 - 2x).

To maximize the area, we need to find the value of x that maximizes the function A.

Taking the derivative of A with respect to x and setting it equal to zero, we can find the critical point. Differentiating A = x(60 - 2x) with respect to x yields dA/dx = 60 - 4x.

Setting dA/dx = 0, we have 60 - 4x = 0. Solving for x gives x = 15.

So, the length of the rectangle should be 15 cm, and the width will be (60 - 2(15)) = 30 cm.

Therefore, the dimensions of the rectangle that would maximize the enclosed area are 15 cm by 30 cm.

The volume of the solid got by rotating the region R about the y-axis is 96π.

None of the given answer choices match the calculated volume of the solid, so the correct option is e) no correct choices.

To find the volume of the solid obtained by rotating the region R about the y-axis, we shall use the cylindrical shells method.

The region R is bounded by the curves y = 5x - x² and y = x. We shall find the points of intersection between these two curves.

To set the equations equal to each other:

5x - x²= x

Simplifying the equation:

5x - x² - x = 0

4x - x² = 0

x(4 - x) = 0

From the above equation, we find two solutions: x = 0 and x = 4.

We shall find the y-values for the points of intersection in order to determine the limits of integration.

We put these x-values into either equation. Let's use the equation y = x.

For x = 0: y = 0

For x = 4: y = 4

Therefore, the region R is bounded by y = 5x - x² and y = x, with y ranging from 0 to 4.

Now, let's set up the integral for finding the volume using the cylindrical shell method:

V = ∫[a,b] 2πx * h * dx

Where:

a = 0 (lower limit of integration)

b = 4 (upper limit of integration)

h = 5x - x² - x (height of the shell)

V = ∫[0,4] 2πx * (5x - x² - x) dx

V = 2π ∫[0,4] (5x² - x³ - x²) dx

V = 2π ∫[0,4] (5x² - x³ - x²) dx

V = 2π ∫[0,4] (4x² - x³) dx

V = 2π [x³ - (1/4)x⁴] |[0,4]

V = 2π [(4³ - (1/4)(4⁴)) - (0³ - (1/4)(0⁴))]

V = 2π [(64 - 64/4) - (0 - 0)]

V = 2π [(64 - 16) - (0)]

V = 2π (48)

V = 96π

Therefore, the volume of the solid got by rotating the region R about the y-axis is 96π.

(1) (0, 0) is an unstable critical point. (2)  (1/√2, 1/√2) is an asymptotically stable critical point.

A critical point is defined as a point in a dynamical system where the vector field vanishes. An equilibrium point is a specific kind of critical point where the vector field vanishes.

If the limit condition for asymptotically stable is satisfied by a critical point of a nonlinear system of differential equations, the critical point is known as asymptotically stable.

It is significant to mention that a critical point is an equilibrium point if the vector field at the point is zero.In this article, we will explain the example of a critical point of a nonlinear system of differential equations that satisfy the limit condition for asymptotically stable.

Consider the system of equations shown below:

[tex]x' = x - y - x(x^2 + y^2)y' = x + y - y(x^2 + y^2)[/tex]

The Jacobian matrix of this system of differential equations is given by:

[tex]Df(x, y) = \begin{bmatrix}1-3x^2-y^2 & -1-2xy\\1-2xy & 1-x^2-3y^2\end{bmatrix}[/tex]

Let’s find the critical points of the system by setting x' and y' to zero.

[tex]x - y - x(x^2 + y^2) = 0x + y - y(x^2 + y^2) = 0[/tex]

Thus, the system's critical points are the solutions of the above two equations. We get (0, 0) and (1/√2, 1/√2).

Let's now determine the stability of these critical points. We use the eigenvalue method for the same.In order to find the eigenvalues of the Jacobian matrix, we must first find the characteristic equation of the matrix.

The characteristic equation is given by:

[tex]det(Df(x, y)-\lambda I) = \begin{vmatrix}1-3x^2-y^2-\lambda  & -1-2xy\\1-2xy & 1-x^2-3y^2-\lambda \end{vmatrix}\\= (\lambda )^2 - (2-x^2-y^2)\lambda  + (x^2-y^2)[/tex]

Thus, we get the following eigenvalues:

[tex]\lambda_1 = x^2 - y^2\lambda_2 = 2 - x^2 - y^2[/tex]

(1) At (0, 0), the eigenvalues are λ1 = 0 and λ2 = 2. Both of these eigenvalues are real and one is positive.

Hence, (0, 0) is an unstable critical point.

(2) At (1/√2, 1/√2), the eigenvalues are λ1 = -1/2 and λ2 = -3/2.

Both of these eigenvalues are negative. Therefore, (1/√2, 1/√2) is an asymptotically stable critical point.The nonlinear system of differential equations satisfies the limit condition for asymptotically stable at (1/√2, 1/√2). Hence, this is an example of a critical point of a nonlinear system of differential equations that satisfies the limit condition for asymptotically stable.

To find the volume generated when the area bounded by the x-axis, the parabola y² = 8(x - 2), and the tangent to this parabola at the point (4, y > 0) is rotated through one revolution about the x-axis, we can use the method of cylindrical shells.

First, we determine the equation of the tangent by finding the derivative of the parabola equation and substituting the x-coordinate of the given point.

To find the limits of integration for the volume integral, we need to find the x-values at which the area bounded by the parabola and the tangent intersects the x-axis.

The equation of the tangent is y = x. The tangent intersects the parabola at (4, 4). To find the limits of integration, we set the parabola equation equal to zero and solve for x, giving us x = 2 as the lower limit and x = 4 as the upper limit.

Finally, we calculate the volume integral using the formula V = ∫[2, 4] 2πxy dx, where x is the distance from the axis of rotation and y is the height of the shell. Evaluating the integral, the volume generated is 64π/3 cubic units.

The equation that is used to determine the population (p) of a town in the year t can be written as p = 525, where 525 is the population that was present when the town was first populated.

According to the problem that has been presented to us, the town had a total population of 525 inhabitants in the year t=0. A consistent population growth rate is not provided, which makes it impossible to calculate the population in each subsequent year t. As a result, it is reasonable to suppose that the population has stayed the same over the years.

In this scenario, the formula for determining the population (p) in any given year t is p = 525, where 525 denotes the town's starting population. According to this method, the population of the town has remained the same throughout the years, despite the fact that more time has passed.

It is essential to keep in mind that this method presupposes that there will be no shifts in the population as a result of variables like birth rates, death rates, immigration rates, or emigration rates. In the event that any of these factors are present and have an effect on the population, the formula will need to be updated to reflect the changes that have occurred.

(a) xz-trace: Fixing the y-coordinate and varying x and z, we set y = constant. The equation of the xz-trace can be obtained by substituting y = constant into the equation of the surface S:

z = f(x, y) = x² + y².

Replacing y with a constant, say y = c, we have:

z = f(x, c) = x² + c².

Therefore, the equation of the xz-trace is z = x² + c², where c is a constant. This represents a family of parabolic curves that are symmetric about the z-axis and open upwards. Each value of c determines a different curve in the xz-plane.

(b) yz-trace: Fixing the x-coordinate and varying y and z, we set x = constant. Again, substituting x = constant into the equation of the surface S, we get:

z = f(c, y) = c² + y².

The equation of the yz-trace is z = c² + y², where c is a constant. This represents a family of parabolic curves that are symmetric about the y-axis and open upwards. Each value of c determines a different curve in the yz-plane.

To sketch the surface S, which is a surface of revolution, we can visualize it by rotating the xz-trace (parabolic curve) around the z-axis. This rotation creates a three-dimensional surface in space.

The surface S represents a paraboloid with its vertex at the origin (0, 0, 0) and opening upwards. The cross-sections of the surface in the xy-plane are circles centered at the origin, with their radii increasing as we move away from the origin. As we move along the z-axis, the surface becomes wider and taller.

The surface S is symmetric about the z-axis, as both the xz-trace and yz-trace are symmetric about this axis. The surface extends infinitely in the positive and negative directions along the x, y, and z axes.

In summary, the yz-trace is given by z = c² + y², representing a family of parabolic curves in the yz-plane. The surface S itself is a three-dimensional surface of revolution known as a paraboloid, symmetric about the z-axis and opening upwards.

To determine the convergence or divergence of the series, we can use the Ratio Test. The Ratio Test states that if the limit of the absolute value of the ratio of consecutive terms of a series is less than 1, then the series converges. Conversely, if the limit is greater than 1 or does not exist, the series diverges.

Let's apply the Ratio Test to the given series: (-2)" n! n=1

We calculate the ratio of consecutive terms:

|(-2)"(n+1)!| / |(-2)"n!|

The absolute value of (-2)" cancels out:

|(n+1)!| / |n!|

Simplifying further, we have:

(n+1)! / n!

The (n+1)! can be expanded as (n+1) * n!

The ratio becomes:

(n+1) * n! / n!

We can cancel out the common factor of n! in the numerator and denominator, leaving us with:

(n+1)

Now, we take the limit as n approaches infinity:

lim(n→∞) (n+1) = ∞

Since the limit is greater than 1, the ratio is greater than 1 for all n. Therefore, the series is divergent. The series is divergent. This is because the limit of the ratio of consecutive terms is greater than 1, indicating that the terms of the series do not approach zero, leading to divergence.

The equation of the tangent line to the curve, after the calculations is, at (1, 1) is y = 7.741x - 6.741.

To find the equation of the tangent line to the curve at the point (1, 1), we need to differentiate the given equation with respect to x and then substitute the values x = 1 and y = 1.

The given equation is:

-28x² + 6.228y + y = -21

Differentiating both sides of the equation with respect to x, we get:

-56x + 6.228(dy/dx) + dy/dx = 0

Simplifying the equation, we have:

(6.228 + 1)(dy/dx) = 56x

7.228(dy/dx) = 56x

Now, substitute x = 1 and y = 1 into the equation:

7.228(dy/dx) = 56(1)

7.228(dy/dx) = 56

dy/dx = 56/7.228

dy/dx ≈ 7.741

The slope of the tangent line at (1, 1) is approximately 7.741.

To find the equation of the tangent line in the mx + b format, we have the slope (m = 7.741) and the point (1, 1).

Using the point-slope form of a linear equation, we have:

y - y₁ = m(x - x₁)

Substituting the values x₁ = 1, y₁ = 1, and m = 7.741, we get:

y - 1 = 7.741(x - 1)

Expanding the equation, we have:

y - 1 = 7.741x - 7.741

Rearranging the equation to the mx + b format, we get:

y = 7.741x - 7.741 + 1

y = 7.741x - 6.741

Therefore, the equation of the tangent line to the curve at (1, 1) is y = 7.741x - 6.741.

The piecewise-defined function is f(x) = x + 5. There are no z-values at which it is discontinuous

(a) To evaluate the limits of f(x), we need to consider the different cases based on the value of x.

For x → -5 (approaching from the left), f(x) = x + 5 → -5 + 5 = 0.

For x → -5 (approaching from the right), f(x) = x + 5 → -5 + 5 = 0.

For x → -5 (approaching from any direction), the limit of f(x) is 0.

(b) The function f(x) = x + 5 is continuous for all values of x since it is a linear function without any jumps, holes, or vertical asymptotes. Therefore, there are no z-values at which f(x) is discontinuous.

In summary, the limits of f(x) as x approaches -5 from any direction are all equal to 0. The function f(x) = x + 5 is continuous for all values of x, and there are no z-values at which it is discontinuous.

d.  The first derivative of h(x) is h'(x) = -3, and the second derivative is h''(x) = 0.

(a) To compute the first and second derivatives of the function f(x) = 14x^2 - 12, we'll differentiate each term separately.

First derivative:

f'(x) = d/dx (14x^2 - 12)

= 2(14x)

= 28x

Second derivative:

f''(x) = d^2/dx^2 (14x^2 - 12)

= d/dx (28x)

= 28

Therefore, the first derivative of f(x) is f'(x) = 28x, and the second derivative is f''(x) = 28.

(b) To find the first derivative of g(t) = f'(t^2 + 2), we need to apply the chain rule. The chain rule states that if h(x) = f(g(x)), then h'(x) = f'(g(x)) * g'(x).

Let's start by finding the derivative of f(x) = 14x^2 - 12, which we computed earlier as f'(x) = 28x.

Now, we can apply the chain rule:

g'(t) = d/dt (t^2 + 2)

= 2t

Therefore, the first derivative of g(t) = f'(t^2 + 2) is:

g'(t) = f'(t^2 + 2) * 2t

= 28(t^2 + 2) * 2t

= 56t(t^2 + 2)

(c) To compute the first and second derivatives of v(s) = ln(s^2 - 4), we'll apply the chain rule and the derivative of the natural logarithm.

First derivative:

v'(s) = d/ds ln(s^2 - 4)

= 1 / (s^2 - 4) * d/ds (s^2 - 4)

= 1 / (s^2 - 4) * (2s)

= 2s / (s^2 - 4)

Second derivative:

v''(s) = d/ds (2s / (s^2 - 4))

= (2(s^2 - 4) - 2s(2s)) / (s^2 - 4)^2

= (2s^2 - 8 - 4s^2) / (s^2 - 4)^2

= (-2s^2 - 8) / (s^2 - 4)^2

Therefore, the first derivative of v(s) is v'(s) = 2s / (s^2 - 4), and the second derivative is v''(s) = (-2s^2 - 8) / (s^2 - 4)^2.

(d) To compute the first and second derivatives of h(x) = 523 - 3x + 14, note that the derivative of a constant is zero.

First derivative:

h'(x) = d/dx (523 - 3x + 14)

= -3

To find the integral of the expression[tex](17x + 17x^2 + 4x + 128) / (x + 16x),[/tex]we can use partial fractions. Let's simplify and factor the expression first:

[tex](17x + 17x^2 + 4x + 128) / (x + 16x)= (17x^2 + 21x + 128) / (17x)= (17x^2 + 21x + 128) / (17x)= (x^2 + (21/17)x + 128/17)[/tex]

Now, let's find the partial fraction decomposition. We need to express [tex](x^2 + (21/17)x + 128/17)[/tex]as the sum of simpler fractions:

[tex](x^2 + (21/17)x + 128/17) = A/x + B/(x + 17)[/tex]

To determine the values of A and B, we can multiply both sides by the denominator:

[tex](x^2 + (21/17)x + 128/17) = A(x + 17) + B(x)[/tex]

Expanding and collecting like terms:

[tex]x^2 + (21/17)x + 128/17 = (A + B) x + 17A[/tex]

By comparing the coefficients of x on both sides, we get two equations:

[tex]A + B = 21/17 ...(1)17A = 128/17 ...(2)[/tex]

From equation (2), we can solve for A:

[tex]A = (128/17) / 17A = 128 / (17 * 17)A = 8/17[/tex]

Substituting the value of A into equation (1), we can solve for B:

[tex](8/17) + B = 21/17B = 21/17 - 8/17B = 13/17[/tex]

Now, we have the partial fraction decomposition:

[tex](x^2 + (21/17)x + 128/17) = (8/17) / x + (13/17) / (x + 17)[/tex]

We can now integrate each term separately:

The graph of y = f(x) has no vertical asymptotes, no horizontal asymptotes, and a slant asymptote given by the equation y = x - 6.

To identify the presence of asymptotes in the graph of y=f(x), we need to examine the behavior of the function as x approaches positive or negative infinity.

For the function f(x) = x² - x - 12, there are no vertical asymptotes because the function is defined and continuous for all real values of x.

There are also no horizontal asymptotes because the degree of the numerator (2) is greater than the degree of the denominator (1) in the function f(x). Horizontal asymptotes occur when the degree of the numerator is less than or equal to the degree of the denominator.

Lastly, there is no slant asymptote because the degree of the numerator (2) is exactly one greater than the degree of the denominator (1). Slant asymptotes occur when the degree of the numerator is one greater than the degree of the denominator.

Therefore, the graph of y=f(x) does not exhibit any vertical, horizontal, or slant asymptotes.

The Lagrange multiplier approach can be used to determine the global extrema of the function (f(x, y, z) = 5x + 4y + 3z) subject to the b(x2 + y2 + z2 = 100).
