To find the partial derivatives of f(x, y) = 3x - 5xy³ - 4y² with respect to x and y, and then determine faz(x, y) = fry(x, y), we compute the partial derivatives and substitute them into the equation for faz(x, y).

Taking the partial derivative of f with respect to x, we have fₓ(x, y) = 3 - 5y³. Taking the partial derivative of f with respect to y, we have fᵧ(x, y) = -15xy² - 8y. Now, substituting these partial derivatives into the equation for faz(x, y) = fry(x, y), we have:

faz(x, y) = fry(x, y)

fₓ(x, y) = fᵧ(x, y)

3 - 5y³ = -15xy² - 8y

Simplifying the equation, we have:

15xy² - 5y³ = -8y - 3

This equation represents the relationship between x and y for the equality faz(x, y) = fry(x, y).

The given series, 5n + 18 / (n(n + 9)), is divergent.

To determine the convergence or divergence of the series, we can examine the behavior of its terms as n approaches infinity. In this case, we have the expression 5n + 18 / (n(n + 9)).

As n grows larger, the dominant term in the numerator becomes 5n, while the dominant term in the denominator becomes n^2. Therefore, we can simplify the expression to 5n / n^2.

Now, we can rewrite this as 5/n, which approaches zero as n tends to infinity. However, for a series to be convergent, the terms must approach zero, which is not the case here. The series diverges since the terms do not converge to zero.

In conclusion, the given series, 5n + 18 / (n(n + 9)), is divergent. The divergence occurs because the terms do not approach zero as n approaches infinity.

The extrema of the function f(x, y) = xy subject to the constraint 4x² + y² - 4 = 0 are:

(x, y) = (1/√5, 2/√5), (-1/√5, -2/√5), (1/√3, -2/√3), (-1/√3, 2/√3).

To find the extrema of the function f(x, y) = xy subject to the constraint 4x² + y² - 4 = 0 using the Lagrange multiplier method, we follow a step-by-step process.

Step 1: Define the function and the constraint equation:

f(x, y) = xy

g(x, y) = 4x² + y² - 4

Step 2: Set up the Lagrangian function:

L(x, y, λ) = f(x, y) - λ(g(x, y))

L(x, y, λ) = xy - λ(4x² + y² - 4)

Step 3: Find the partial derivatives of the Lagrangian function:

∂L/∂x = y - 8λx

∂L/∂y = x - 2λy

∂L/∂λ = 4x² + y² - 4

Step 4: Set the partial derivatives equal to zero and solve the system of equations:

y - 8λx = 0 (Equation 1)

x - 2λy = 0 (Equation 2)

4x² + y² - 4 = 0 (Equation 3)

Step 5: Solve Equation 1 and Equation 2 simultaneously:

Rearrange Equation 1 to get y = 8λx

Substitute y in Equation 2:

x - 2λ(8λx) = 0

Simplify: 1 - 16λ² = 0

Solve for λ: λ = ±1/√16 = ±1/4

Step 6: Substitute the values of λ into Equation 1 and Equation 3 to find the corresponding values of x and y:

For λ = 1/4:

y = 8(1/4)x = 2x

Substituting λ = 1/4 and y = 2x into Equation 3:

4x² + (2x)² - 4 = 0

Simplify: 20x² - 4 = 0

Solve for x: x = ±√(4/20) = ±1/√5

For λ = -1/4:

y = 8(-1/4)x = -2x

Substituting λ = -1/4 and y = -2x into Equation 3:

4x² + (-2x)² - 4 = 0

Simplify: 12x² - 4 = 0

Solve for x: x = ±√(4/12) = ±1/√3

Step 7: Calculate the corresponding values of y using the equations y = 2x and y = -2x:

For x = 1/√5, y = 2(1/√5) = 2/√5

For x = -1/√5, y = 2(-1/√5) = -2/√5

For x = 1/√3, y = -2(1/√3) = -2/√3

For x = -1/√3, y = -2(-1/√3) = 2/√3

Therefore, the extrema of the function f(x, y) = xy subject to the constraint 4x² + y² - 4 = 0 are:

(x, y) = (1/√5, 2/√5), (-1/√5, -2/√5), (1/√3, -2/√3), (-1/√3, 2/√3).

\[f(0) = 3(0) + 16 = 16\]

\[f'(0) = 3\]

\[f''(0) = 0\]

To find the power series representation of the function f(8x) centered at 0, we can substitute 8x into the given geometric series expression for f(x).

The geometric series is given by:

f(x) = Σ  [tex]x^k[/tex] , for |x| < 1

Substituting 8x into the series, we have:

f(8x) = Σ [tex]8^k[/tex] * [tex]x^k[/tex]

Simplifying further, we obtain:

f(8x) = Σ [tex]8^k[/tex] * [tex]x^k[/tex]

Now, we can rewrite the series in terms of a new power series:

f(8x) = Σ [tex]8^k[/tex] * [tex]x^k[/tex]

The interval of convergence of the new power series centered at 0 can be determined by examining the original interval of convergence for the geometric series, which is |x| < 1. Since we substituted 8x into the series, we need to consider the interval for which |8x| < 1.

Time it takes for the ball to hit the ground can be found by setting H(t) = 0 and solving for t, which in this case would be approximately 5 seconds.

The equation H(t) = -16t² + 96t + 80 represents a quadratic function that describes the height of the ball above the ground at time t. The term -16t² represents the effect of gravity on the ball's vertical position, with a negative coefficient indicating the downward acceleration due to gravity.

The term 96t represents the initial upward velocity of the ball, and the constant term 80 represents the initial height of the ball above the ground.

To find specific information about the ball's motion, we can analyze the equation.

The maximum height the ball reaches can be determined by finding the vertex of the parabolic function, which occurs at t = -b/(2a). In this case, the maximum height is reached at t = -96/(2*-16) = 3 seconds.

Plugging this value into the equation gives the maximum height as H(3) = -16(3)² + 96(3) + 80 = 200 feet. Additionally, the time it takes for the ball to hit the ground can be found by setting H(t) = 0 and solving for t, which in this case would be approximately 5 seconds.

It will take approximately 8.087 years for the total debt to exceed $140,000.

(a) To find the total debt function, we need to integrate the given rate of debt with respect to time:

∫(600t + 8t + 16) dt = 300t^2 + 4t^2 + 16t + C

where C is the constant of integration. Since we know that the company had accumulated $68,400 in debt by the 9th year, we can use this information to solve for C:

300(9)^2 + 4(9)^2 + 16(9) + C = 68,400

C = 46,620

Therefore, the total debt function is:

D(t) = 300t^2 + 4t^2 + 16t + 46,620

(b) To find how many years must pass before the total debt exceeds $140,000, we can set D(t) equal to $140,000 and solve for t:

300t^2 + 4t^2 + 16t + 46,620 = 140,000

304t^2 + 16t - 93,380 = 0

Using the quadratic formula, we get:

t = (-16 ± sqrt(16^2 - 4(304)(-93,380))) / (2(304))

t ≈ -1.539 or t ≈ 8.087

Since time cannot be negative in this context, we disregard the negative solution and conclude that it will take approximately 8.087 years for the total debt to exceed $140,000.

The given differential equation is y" + 4y + 5y = (t - 27), with the initial condition y(0) = 0. To solve the given differential equation, we need to take the Laplace transform of both sides and solve for Y(s).

y" + 4y + 5y = (t - 27)

=> L{y" + 4y + 5y} = L{(t - 27)}

=> s²Y(s) - sy(0) - y'(0) + 4Y(s) + 5Y(s) = 1/s² - 27/s

=> s²Y(s) + 4Y(s) + 5Y(s) = 1/s² - 27/s

=> (s² + 4s + 5)Y(s) = (s - 27)/s²

=> Y(s) = (s - 27)/(s(s²+ 4s + 5))

Now, we need to use partial fraction decomposition to find the inverse Laplace transform of Y(s).

Y(s) = (s - 27)/(s(s² + 4s + 5))

=> Y(s) = A/s + (Bs + C)/(s² + 4s + 5)

Multiplying both sides by s(s² + 4s + 5), we get:

(s - 27) = A(s² + 4s + 5) + (Bs + C)s

Taking s = 0, we get:0 - 27 = 5A

=> A = -27/5Taking s = -2 - i, we get:-29 - 4i = (-2 - i)B + C

=> B = -3/5 - 11i/25 and C = 21/5 + 14i/25Thus, we have:

Y(s) = -27/5s - 3/5 (s + 2)/(s² + 4s + 5) - 14/25 (-1 + 2i)/(s² + 4s + 5) + 14/25 (1 + 2i)/(s² + 4s + 5)

S^2(S + 2)(S + 3) = S^2(S + 2)(S + 3)

Next, we write the expression as a sum of partial fractions:

G(S) = 5S + 5 / [S^2(S + 2)(S + 3)] = A/S + B/S^2 + C/(S + 2) + D/(S + 3)

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

5S + 5 = A(S + 2)(S + 3) + BS(S + 3) + CS^2(S + 3) + D(S^2)(S + 2)

Expanding and collecting like terms, we get:

5S + 5 = (A + B + C)S^3 + (2A + 3A + B + C + D)S^2 + (6A + 9A + 3B + C)S + 6A

By equating coefficients, we can solve for A, B, C, and D. After finding the values, we can rewrite G(S) in terms of the partial fractions. Finally, by taking the inverse Laplace transform of each term, we obtain the expression for f(t) as 5 + 5e^(-2t) - 5e^(-3t).

To evaluate the integral of g(x) using the Fundamental Theorem of Calculus, we need to find its antiderivative F(x) and then apply the definite integral.

Let's find the antiderivative F(x) of g(x) step by step:

∫(ln(t) - √2) dx

Using the linearity property of integration, we can split this into two separate integrals:

∫ln(t) dx - ∫√2 dx

Now, let's evaluate each integral separately:

∫ln(t) dx

Using the integral of ln(x), which is x * ln(x) - x, we have:

= t * ln(t) - t + C1

Next, let's evaluate the second integral:

∫√2 dx

The integral of a constant is simply the constant multiplied by x:

= √2 * x + C2

Now, we can combine the results:

F(x) = t * ln(t) - t + √2 * x + C

Finally, to find the value of the integral i 19(x), we can substitute the limits of integration into the antiderivative:

i 19(x) = F(19) - F(x)

= (19 * ln(19) - 19 + √2 * 19 + C) - (x * ln(x) - x + √2 * x + C)

= 19 * ln(19) - 19 + √2 * 19 - x * ln(x) + x - √2 * x

So, i 19(x) = 19 * ln(19) - 19 + √2 * 19 - x * ln(x) + x - √2 * x.

Since we don't have specific numbers for A and B, we cannot calculate the probability accurately without more information.

We need some further information to determine the likelihood that a randomly chosen survey respondent has a heart rate below 80 bpm and is not in the marching band. We specifically need to know how many persons were questioned in total, how many had heart rates under 80, and how many were not marching band members.

Assuming we have this knowledge, we may apply the formula below:

Probability is calculated as follows: (Number of favourable results) / (Total number of probable results)

Let's assume that there were N total respondents to the survey, A were those with a heart rate under 80, and B were not members of the marching band.

Without more information, we cannot determine the probability precisely because A and B are not given in precise numerical terms. However, we can use those values to the formula to get the likelihood if we are given the values for A and B.

In this solution, we express each given vector in terms of the standard basis vectors i, j, and k. Each component of the vector represents the coefficient of the corresponding basis vector. By writing the vector in this form, we can easily understand the vector's direction and magnitude.

For example, the vector (-9, -4) can be represented as -9i - 4j, indicating that it has a coefficient of -9 in the i direction and a coefficient of -4 in the j direction. Similarly, the vector (5, 9, 2) can be expressed as 5i + 9j + 2k, showing that it has coefficients of 5, 9, and 2 in the i, j, and k directions, respectively.

Writing vectors in terms of the standard basis vectors helps us break down the vector into its individual components and understand its behavior in different coordinate directions.

The two numbers are 27 and 11, with the smaller number first.

Let's denote the two numbers as x and y.

According to the problem, one number (let's say x) is six less than three times the other number (y).

This can be written as:

x = 3y - 6 ... (Equation 1)

The sum of the numbers is given as 38:

x + y = 38 ... (Equation 2)

We can now solve these two equations simultaneously to find the values of x and y.

Substituting the value of x from Equation 1 into Equation 2, we have:

(3y - 6) + y = 38

Simplifying the equation:

4y - 6 = 38

Adding 6 to both sides:

4y = 44

Dividing both sides by 4:

y = 11

Now, substituting the value of y back into Equation 1:

x = 3(11) - 6

x = 33 - 6

x = 27

Therefore, the two numbers are 27 and 11, with the smaller number first.

To summarize:

x = 27

y = 11

The area of the surface of the sphere x2 + y2 + z2 = 25 inside the cylinder x2 + y2 = 9 is 57.22 square units. The sphere is inside the cylinder. We can find the area of the sphere and then the area of the remaining spaces.

To find the area of this surface, we can use calculus. We can solve for z as a function of x and y by rearranging the sphere equation:

$z^2 = 25 - x^2 - y^2$

$z = \pm\sqrt{25 - x^2 - y^2}$

The upper half of the sphere (positive z values) is the one intersecting with the cylinder, so we consider that for our calculations.

We can then use the surface area formula for double integrals:

$A = \iint_S dS$

where S is the curved surface of the spherical cap. Since the surface is symmetric about the origin, we can work in the upper half of the x-y plane and then multiply by 2 at the end. We can also use polar coordinates, with radius r and angle $\theta$:

$x = r\cos(\theta)$

$y = r\sin(\theta)$

$dS = \sqrt{(\frac{\partial z}{\partial x})^2 + (\frac{\partial z}{\partial y})^2 + 1} dA$

where $dA = r dr d\theta$ is the area element in polar coordinates. We have:

$\frac{\partial z}{\partial x} = -\frac{x}{\sqrt{25 - x^2 - y^2}}$

$\frac{\partial z}{\partial y} = -\frac{y}{\sqrt{25 - x^2 - y^2}}$

So:

$dS = \sqrt{1 + \frac{x^2 + y^2}{25 - x^2 - y^2}} r dr d\theta$

The limits of integration are:

$0 \leq \theta \leq 2\pi$

$0 \leq r \leq 3$ (inside the cylinder)

$0 \leq z \leq \sqrt{25 - x^2 - y^2}$ (on the sphere)

Converting to polar coordinates, we have:

$0 \leq \theta \leq 2\pi$

$0 \leq r \leq 3$

$0 \leq z \leq \sqrt{25 - r^2}$

Therefore:

$A = 2\iint_S dS = 2\int_0^{2\pi} \int_0^3 \int_0^{\sqrt{25 - r^2}} \sqrt{1 + \frac{r^2}{25 - r^2}} r dz dr d\theta$

Doing the innermost integral first, we get:

$2\int_0^{2\pi} \int_0^3 r\sqrt{1 + \frac{r^2}{25 - r^2}} \sqrt{25 - r^2} dr d\theta$

Making the substitution $u = 25 - r^2$, we have:

$2\int_0^{2\pi} \int_{16}^{25} \sqrt{u} du d\theta$

Solving this integral, we get:

$A = 2\int_0^{2\pi} \frac{2}{3} (25^{3/2} - 16^{3/2}) d\theta = \frac{4}{3} (25^{3/2} - 16^{3/2}) \pi \approx 57.22$

So the portion of the sphere inside the cylinder has area approximately 57.22 square units.

The work done can also be computed by explicitly evaluating a line integral along the curve, consisting of the line segment from A to a point P, followed by the line segment from P to B.

(a) The Fundamental Theorem for Line Integrals states that if a vector field F is conservative, then the work done along any path between two points A and B is simply the difference in the potential function evaluated at those points. In this case, we need to determine if the given force field F(x, y, z) is conservative by checking if its curl is zero. The curl of F can be computed as (∂F₃/∂y - ∂F₂/∂z, ∂F₁/∂z - ∂F₃/∂x, ∂F₂/∂x - ∂F₁/∂y). After calculating the curl, if it turns out to be zero, we can proceed to evaluate the potential function at points A and B and find the difference to determine the work done.

(b) To explicitly evaluate the line integral along the curve from A to P and then from P to B, we need to parameterize the two line segments. For the first line segment from A to P, we can use the parameterization r(t) = (1, 0, -1) + t(0, 2, 0) where t varies from 0 to 1. Similarly, for the second line segment from P to B, we can use the parameterization r(t) = (1, 2, -1) + t(1, 0, -2) where t varies from 0 to 1. By plugging these parameterizations into the line integral formula ∫F(r(t))·r'(t) dt and integrating separately for each segment, we can find the work done and then sum up the two results to obtain the total work done along the curve from A to B.
