After 1 year: $240.00 million/year

After 5 years: $2,400.00 million/year

After 6 years: $2,880.00 million/year

Let's have stepwise solution:

To determine how fast the total receipts are changing after 1 year, 5 years, and 6 years, we need to find the derivative of the function T(x) with respect to x. Then we can evaluate the derivatives at the given values of x.

To find the derivative of T(x), we'll differentiate each term separately:

d(T(x))/dx = d(120x^2)/dx + d(x^2)/dx + d(4)/dx

= 240x + 2x

Simplifying this expression, we have:

d(T(x))/dx = 242x

After calculations we come to know that the profit-maximizing levels of Q1, Q2, P1, and P2 are $10 and the solution is maximum.

The demand functions for the product in the two markets are, respectively, P1 = 10-20, and P2 = 20-Q, where P, and P, are prices charged in each market. Also assume that the cost function for producing the single product is, TC = 215 + 4Q where Q = Q1 + Q2 is total output.

We need to find the profit-maximizing levels of Q1, Q2, P1, and P2.1) To find the demand function, we need to differentiate the given demand function with respect to price. So, we haveQ1 = 10 - P1Q2 = 20 - P22) We know that, TR = P*Q. So, for each market, TR1 = P1 * Q1TR2 = P2 * Q23)

Now, we can get the expression for profits as follows :π1 = TR1 - TCπ2 = TR2 - TC Where TC = 215 + 4Q And, Q = Q1 + Q2= Q1 + (20 - P2)

Hence,π1 = (10 - P1) (10 - P1 - 20) - (215 + 4Q1 + 4(20 - P2))π2 = (20 - Q2) (Q2) - (215 + 4Q2 + 4Q1)

Expanding and simplifying π1 = -P1^2 + 20P1 - Q1 - 435 - 4Q2π2 = -Q2^2 + 20Q2 - Q1 - 215 - 4Q1

Now, we need to differentiate π1 and π2 with respect to P1, Q1, and Q2 respectively, to get the first-order conditions as below:∂π1/∂P1 = -2P1 + 20= 0∂π1/∂Q1 = -1= 0∂π1/∂Q2 = -4= 0∂π2/∂Q2 = -2Q2 + 20 - 4Q1= 0∂π2/∂Q1 = -1 - 4Q2= 0

Now, we can solve these equations to get the optimal values of P1, P2, Q1, and Q2. After solving these equations, we get the following optimal values:P1 = $10P2 = $10Q1 = 0Q2 = 5

Therefore, the profit-maximizing levels of Q1, Q2, P1, and P2 are as follows:Q1 = 0Q2 = 5P1 = $10P2 = $10

The Second-Order Condition: To check whether the solution obtained is a maximum, we need to check the second-order conditions. So, we calculate the following:∂^2π1/∂P1^2 = -2<0;

Hence, it is a maximum.∂^2π1/∂Q1^2 = 0∂^2π1/∂Q2^2 = 0∂^2π2/∂Q2^2 = -2<0; Hence, it is a maximum.∂^2π2/∂Q1^2 = 0

Hence, the solution is maximum.

False. A local extreme point of a polynomial function f(x) can not occur when f'(x) = 0.

A local extreme point of a polynomial function f(x) can occur when f'(x) = 0, but it is not a necessary condition. The critical points of a function, where f'(x) = 0 or f'(x) is undefined, represent potential locations of extreme points such as local maxima or minima.

However, it is important to note that not all critical points correspond to extreme points. The behavior of the function around the critical points needs to be further analyzed using the second derivative test or other methods to determine if they are indeed local extrema.

Therefore, while f'(x) = 0 can indicate a potential extreme point, it is not the only criterion for the presence of a local extreme.

The equation of the hyperbola with a vertical transverse axis, one endpoint at (4,5), and asymptotes y - x = 0 and y + x = 8 is (x-4)^2/9 - (y-5)^2/16 = 1.

Given that the hyperbola has a vertical transverse axis, we can use the standard form equation for a hyperbola with a vertical transverse axis:

(x-h)^2/a^2 - (y-k)^2/b^2 = 1

where (h, k) represents the coordinates of the center of the hyperbola.

Since the asymptotes are y - x = 0 and y + x = 8, we can rewrite them in slope-intercept form:

y = x and y = -x + 8.

The center of the hyperbola lies at the intersection of the asymptotes, which is (4, 4) (solving the system of equations y = x and y + x = 8).

Now, we can determine the values of a and b by considering the distance between the center (4, 4) and the endpoint (4, 5). The distance between these points is the value of a.

Using the distance formula:

a = sqrt((4-4)^2 + (5-4)^2) = 1

To determine the value of b, we consider the distance from the center (4, 4) to the asymptotes. The distance from the center to an asymptote is the value of b.

Using the distance formula and the equation y = x (one of the asymptotes):

b = sqrt((4-0)^2 + (4-0)^2)/sqrt(2) = 4sqrt(2)

Therefore, the equation of the hyperbola is (x-4)^2/9 - (y-5)^2/16 = 1.

There are three intervals of increase/decrease: (-∞, -4], (-4, 5/3), and [5/3, ∞).The maximum point is (-4, 76) and the minimum point is (5/3, 170/27) and the graph is concave up on (-∞, -2] and concave down on [-2, ∞).

Let's have further explanation:

(1) To find the intervals of increase/decrease, take the derivative of the function: f'(x) = 3x² + 12x - 15. Then, set the derivative equation to 0 to find any critical points: 3x² + 12x - 15 = 0 → 3x(x + 4) - 5(x + 4) = 0 → (x + 4)(3x - 5) = 0 → x = -4, 5/3. To find the intervals of increase/decrease, evaluate the function at each critical point and compare the values. f(-4) = (-4)³ + 6(-4)² - 15(-4) - 10 = 64 - 48 + 60 + 10 = 76 and f(5/3) = (5/3)³ + 6(5/3)² - 15(5/3) - 10 = 125/27 + 200/27 – 75/3 – 10 = 170/27. There are three intervals of increase/decrease: (-∞, -4], (-4, 5/3), and [5/3, ∞). The function is decreasing in the first interval, increasing in the second interval, and decreasing in the third interval.

(2) To find the local maximum and minimum points, test the critical points on a closed interval. To do this, use the Interval Notation (a, b) to evaluate the function at two points, one before the critical point and one after the critical point. For the first critical point: f(-5) = (-5)³ + 6(-5)² - 15(-5) - 10 = -125 + 150 - 75 - 10 = -60 < 76 = f(-4). This tells us the local maximum is at -4. For the second critical point: f(4) = (4)³ + 6(4)² - 15(4) - 10 = 64 + 96 - 60 - 10 = 90 < 170/27 = f(5/3). This tells us the local minimum is at 5/3. Therefore, the maximum point is (-4, 76) and the minimum point is (5/3, 170/27).

(3) To find the interval on which the graph is concave up/down, take the second derivative and set it equal to 0: f''(x) = 6x + 12 = 0 → x = -2. Evaluate the function at -2 and compare the values to the values of the endpoints. f(-3) = (-3)³ + 6(-3)² - 15(-3) - 10 = -27 + 54 - 45 - 10 = -68 < -2 = f(-2) < 0 = f(-1). This tells us the graph is concave up on (-∞, -2] and concave down on [-2, ∞).

In given , the variable X represents the total number of towels drawn from the bag until a red towel is obtained. Since towels are drawn without replacement, this situation follows a geometric distribution. The probability distribution of X can be calculated as follows:

P(X = k) = (3/7)^(k-1) * (4/7)

The relationship between the functions g(x) and ƒ(x) defined through an integral is that g(x) represents the derivative of ƒ(x). In mathematical notation, we can express this relationship as g(x) = dƒ(x)/dx, where d/dx represents the derivative operator.

When we define a function ƒ(x) through an integral, such as ƒ(x) = ∫[a to x] g(t) dt, we can interpret g(x) as the rate of change of ƒ(x). In other words, g(x) represents the instantaneous slope of the function ƒ(x) at any given point x. The derivative g(x) can be obtained by differentiating ƒ(x) with respect to x. Thus, g(x) = dƒ(x)/dx. This relationship allows us to find the derivative of a function defined through an integral by applying the fundamental theorem of calculus. The derivative g(x) captures the local behavior of the function ƒ(x) and provides valuable information about its rate of change.

The assumptions and conditions that must be met to find a 95% confidence interval for a population proportion are: Independence Assumption, Random Sampling, and Sample size condition: np and nq > 10.

Independence Assumption: This assumption states that the sampled individuals or observations should be independent of each other. This means that the selection of one individual should not influence the selection of another. It is essential to ensure that each individual has an equal chance of being selected.

Random Sampling: Random sampling involves selecting individuals from the population randomly. This helps in reducing bias and ensures that the sample is representative of the population. Random sampling allows for generalization of the sample results to the entire population.

Sample size condition: np and nq > 10: This condition is based on the properties of the sampling distribution of the proportion. It ensures that there are a sufficient number of successes (np) and failures (nq) in the sample, which allows for the use of the normal distribution approximation in constructing the confidence interval.

The condition n > 30 is not specifically required to find a 95% confidence interval for a population proportion. It is a rule of thumb that is often used to approximate the normal distribution when the exact population distribution is unknown.

Social scientists gather data from samples instead of populations because c. populations are often too large to test.

Social scientists often cannot test an entire population due to its size, so they gather data from a smaller group or sample that is representative of the larger population. This allows them to make inferences about the larger population based on the data collected from the sample. The sample size must be large enough to accurately represent the population, but it is not necessarily larger or more complete than the population itself.

The derivative of y = 3 ln x + 7 log₃ x with respect to x is given by dy/dx = 10 / x.

To find the derivative of y = 3 ln x + 7 log₃ x, we can apply the rules of differentiation.

Let's start by finding the derivative of the first term, 3 ln x. The derivative of ln x with respect to x is given by 1/x. Therefore, the derivative of 3 ln x is 3/x.

In this case, we have log₃ x, which can be expressed as log x / log 3. Now we can differentiate the expression.

The derivative of log x with respect to x is given by 1/x. Therefore, the derivative of 7 log x is 7 * (1/x). However, we still need to differentiate log 3, which is a constant.

Since log 3 is a constant, its derivative with respect to x is 0. Thus, we can ignore it while finding the derivative.

Combining the derivatives of the two terms, we have:

dy/dx = (3/x) + 7 * (1/x)

To simplify this expression, we can find a common denominator of x for both terms:

dy/dx = (3 + 7) / x

Simplifying further, we have:

dy/dx = 10 / x

So, the derivative of y = 3 ln x + 7 log₃ x with respect to x is dy/dx = 10 / x.

Answer:

The graph of the quadratic function f(x) = a(x - h)^2 + k is a parabola with vertex (h, k).

Step-by-step explanation:

In standard form, the quadratic function f(x) = a(x - h)^2 + k represents a parabola. The values of h and k determine the vertex of the parabola.

The value h represents the horizontal shift of the vertex from the origin. If h is positive, the vertex is shifted to the right, and if h is negative, the vertex is shifted to the left.

The value k represents the vertical shift of the vertex from the origin. If k is positive, the vertex is shifted upward, and if k is negative, the vertex is shifted downward.

Therefore, the vertex of the parabola is located at the point (h, k), which corresponds to the values inside the parentheses in the function f(x).

In the given function f(x) = a(x - h)^2 + k, the vertex is at (h, k), where h and k can be determined by comparing the equation to the standard form

Six years ago, their ages are:

x - 6 and y - 6 respectively

Six years from now, their ages will be:

x + 6 and y + 6

Six years ago, Joe Foster was two years more than five times as old as his daughter.

(x - 6) = 5(y-6) + 2    

Simplify

x - 6 = 5y - 30 + 2

x = 5y -30 + 2 + 6

x = 5y - 22   ---equation 1

Six years from now, he will be 11 years more than twice as old as she will be.

(x + 6) = 2(y+6) + 11  

Simplify

x + 6 = 2y + 12 + 11

x = 2y + 12 + 11 -6

x = 2y + 17    ----equation 2

Subtract equation 2 from equation 1

      x = 5y - 22

    -(x = 2y + 17)

      0 = 3y - 39

Ava and Kelly will be 3/4 mile apart after 22.5 minutes.

To determine when Ava and Kelly will be 3/4 mile apart, we can consider their relative speed. The relative speed is the difference between their individual speeds.

Ava's speed = 6 miles per hour

Kelly's speed = 8 miles per hour

The relative speed of Ava and Kelly is:

Relative speed = Kelly's speed - Ava's speed

= 8 miles per hour - 6 miles per hour

= 2 miles per hour

This means that Ava and Kelly are moving away from each other at a rate of 2 miles per hour.

To calculate the time it takes for them to be 3/4 mile apart, we can use the formula:

Distance = Speed × Time

In this case, the distance they need to cover is 3/4 mile, and the relative speed is 2 miles per hour.

3/4 mile = 2 miles per hour × Time

Simplifying the equation:

3/4 = 2 × Time

Dividing both sides by 2:

3/4 × 1/2 = Time

3/8 = Time

Therefore, it will take Ava and Kelly 3/8 hours (or 22.5 minutes) to be 3/4 mile apart.

Thus, Ava and Kelly will be 3/4 mile apart after 22.5 minutes.

The volume of the solid region Q cut from the sphere x^2+y^2+z^2=4 by the cylinder r = 2 sintheta is (8/45) π.

Since the cylinder is defined in polar coordinates, we will use polar coordinates to solve this problem.

The equation of the sphere is x^2 + y^2 + z^2 = 4, which can be rewritten in terms of polar coordinates as:

r^2 + z^2 = 4     (1)

The equation of the cylinder is r = 2 sin(theta), which again can be rewritten as r^2 = 2r sin(theta):

r^2 - 2r sin(theta) = 0

r(r - 2 sin(theta)) = 0

So, either r = 0 or r = 2 sin(theta).

We want to find the volume of the solid region Q that is cut from the sphere by the cylinder. Since the cylinder is symmetric about the z-axis, we only need to consider the part of the sphere in the first octant (x, y, z > 0) that lies inside the cylinder.

In polar coordinates, the limits of integration are:

0 ≤ r ≤ 2 sin(theta)

0 ≤ theta ≤ π/2

0 ≤ z ≤ sqrt(4 - r^2)

Using the cylindrical coordinate triple integral, we can write the volume of Q as:

V = ∫∫∫Q dV

= ∫∫∫Q r dz dr dtheta

= ∫0^(π/2) ∫0^(2 sin(theta)) ∫0^(sqrt(4-r^2)) r dz dr dtheta

= ∫0^(π/2) ∫0^(2 sin(theta)) r(sqrt(4-r^2)) dr dtheta

= ∫0^(π/2) [-1/3 (4 - r^2)^(3/2)]_0^(2 sin(theta)) dtheta

= ∫0^(π/2) [-8/3 (sin^2(theta))^3/2 + 8/3] dtheta

= [16/9 - 32/15] π/2

= (8/45) π

Therefore, the volume of the solid region Q cut from the sphere x^2+y^2+z^2=4 by the cylinder r = 2 sin(theta) is (8/45) π.

The equation of the aircraft parallel to the yz-plane is y = -3. The equation of the plane parallel to the xz-plane is x = 5. The equation of the plane parallel to the xy-plane is z = 2.

To discover the equation of a plane via a given factor parallel to a particular plane, we need to recall the regular vector of the given plane.

A plane parallel to the yz-aircraft:

Since the aircraft is parallel to the yz-aircraft, its ordinary vector should be perpendicular to the yz-plane, which means it has an x-issue same to 0. The factor (5, -3, 2) lies on this aircraft, so any vector parallel to the aircraft may be used because of the ordinary vector. Let's pick out the vector (0, 1, 0) because of the regular vector. Using the point-regular form of an aircraft equation, the equation of the plane parallel to the yz-aircraft is:

0(x - 5) + 1(y + 3) + 0(z - 2) = 0

Simplifying, we've:

y + 3 = 0

The equation of the aircraft parallel to the yz-aircraft is y = -3.

A plane parallel to the xz-aircraft:

Similar to the previous case, since the plane is parallel to the xz-plane, its regular vector need to have a y-aspect of zero. Again, using the factor (five, -3, 2), we are able to pick the vector (1, 0, 0) because of the ordinary vector. Applying the point-normal shape, the equation of the plane parallel to the xz-aircraft is:

1(x - 5) + 0(y + 3) + 0(z - 2) = 0

Simplifying, we've got:

x - 5 = 0

The equation of the plane parallel to the xz-aircraft is x = 5.

A plane parallel to the xy-aircraft:

For a plane parallel to the xy-aircraft, the normal vector should have a z-factor of 0. Again, with the use of the point (5, -3, 2), we are able to pick out the vector (0, 0, 1) as the everyday vector. Applying the point-everyday shape, the equation of the plane parallel to the xy-plane is:

0(x - 5) + 0(y + three) + 1(z - 2) = 0

Simplifying, we've got:

z - 2 = 0

The equation of the plane parallel to the xy-plane is z = 2.

The values of a and b that make the function continuous are a = 3 and b = -11.

To make the function continuous, we need to ensure that the function values match at the points where the function changes its definition.

At x = -1, we have:

f(-1) = 8(-1) = -8

At x = 1, we have:

f(1) = a(1) + b

Setting these two function values equal, we have:

-8 = a(1) + b

At x = 1, the derivative of the left and right portions of the function should also match to maintain continuity. Taking the derivative of f(x) for x > 1, we have:

f'(x) = 3

Setting this equal to the derivative of the middle portion of the function, we have:

3 = a

Substituting the value of a into the equation -8 = a + b, we get:

-8 = 3 + b

Simplifying, we find:

b = -11

Therefore, the values of a and b that make the function continuous are a = 3 and b = -11.

The amount of time in REM sleep can be modeled with a random variable probability density function. the probability that the amount of time in REM sleep is less than 7 minutes is approximately 0.004375. , the probability that the amount of time in REM sleep lasts between 13 and 24 minutes is approximately 0.006875.

To determine the probabilities mentioned, we need to work with the probability density function (PDF) rather than the cumulative distribution function (CDF) you provided. The PDF is denoted by f(x), which can be obtained by differentiating the CDF, F(x), with respect to x.

Given F(x) = x/1600, we can differentiate it to obtain the PDF:

f(x) = dF(x)/dx = 1/1600.

Now we can proceed to calculate the probabilities:

1. To determine the probability that the amount of time in REM sleep is less than 7 minutes, we integrate the PDF from 0 to 7:

P(X < 7) = ∫[0 to 7] f(x) dx

        = ∫[0 to 7] (1/1600) dx

        = (1/1600) * [x] evaluated from 0 to 7

        = (1/1600) * (7 - 0)

        = 7/1600

        ≈ 0.004375.

Therefore, the probability that the amount of time in REM sleep is less than 7 minutes is approximately 0.004375.

2. To determine the probability that the amount of time in REM sleep lasts between 13 and 24 minutes, we integrate the PDF from 13 to 24:

P(13 ≤ X ≤ 24) = ∫[13 to 24] f(x) dx

              = ∫[13 to 24] (1/1600) dx

              = (1/1600) * [x] evaluated from 13 to 24

              = (1/1600) * (24 - 13)

              = 11/1600

              ≈ 0.006875.

Therefore, the probability that the amount of time in REM sleep lasts between 13 and 24 minutes is approximately 0.006875.

The indefinite integral of |cosec(x) tan(2x)| dx is |cosec(x)| + C.

To find the indefinite integral of |cosec(x) tan(2x)| dx, we can split the absolute value into two cases based on the sign of cosec(x).Case 1: If cosec(x) > 0, then the integral becomes ∫(cosec(x) tan(2x)) dx. By using the substitution u = cos(x), du = -sin(x) dx, we can rewrite the integral as ∫(-du/tan(2x)). The integral of -du/tan(2x) can be evaluated using the substitution v = 2x, dv = 2dx. Substituting these values, we get -∫(du/tan(v)) = -ln|sec(v)| + C = -ln|sec(2x)| + C.Case 2: If cosec(x) < 0, then the integral becomes ∫(-cosec(x) tan(2x)) dx.

By using the substitution u = -cos(x), du = sin(x) dx, we can rewrite the integral as ∫(du/tan(2x)). Using the same substitution v = 2x, dv = 2dx, we get ∫(du/tan(v)) = ln|sec(v)| + C = ln|sec(2x)| + C.Combining the results from both cases, the indefinite integral of |cosec(x) tan(2x)| dx is |cosec(x)| + C, where C is the constant of integration.

The statement to be proven is A ⊆ B, which means that set A is a subset of set B. To prove this, we need to show that every element of A is also an element of B.

Suppose we have an arbitrary element x ∈ A. Since (x ∈ A) ∧ (A ⊆ B), it follows that x ∈ B, which means that x is also an element of B. Since this holds for every arbitrary element of A, we can conclude that A ⊆ B.

In other words, if for every element x, if (x ∈ A) ∧ (A ⊆ B), then it implies that x ∈ B. This confirms that every element in A is also in B, thereby establishing the statement A ⊆ B as true.

c. Sine- 0°, 180°, and 360°. Cosine- 90° and 270°

The sine function represents the vertical coordinate of points on the unit circle, while the cosine function represents the horizontal coordinate. For the sine function, as we move counterclockwise from 0° to 90°, the y-coordinate increases, hence sine increases. From 90° to 270°, the y-coordinate decreases, resulting in a decreasing sine.

Finally, from 270° to 360°, the y-coordinate increases again. Similarly, for the cosine function, as we move counterclockwise from 0° to 90°, the x-coordinate increases, hence cosine increases. From 90° to 180°, the x-coordinate decreases, resulting in a decreasing cosine.

Finally, from 180° to 270°, the x-coordinate decreases again. Sine is equal to 0 at 0°, 180°, and 360° because those angles correspond to the y-coordinate being 0 on the unit circle. Cosine is equal to 0 at 90° and 270° because those angles correspond to the x-coordinate being 0 on the unit circle.

The problem states that the starting salaries for engineering students have a mean of $2,600 and a standard deviation of $1,600. We are asked to find the probability that a random sample of 64 students from the school will have an average salary of more than $3,000 is approximately 2.28%.

To solve this problem, we can use the Central Limit Theorem, which states that the distribution of sample means tends to be approximately normal, regardless of the shape of the population distribution, as the sample size increases.

Since the sample size is large (n = 64), we can assume that the distribution of sample means will be approximately normal. The mean of the sample means will still be $2,600, but the standard deviation of the sample means, also known as the standard error, will be the population standard deviation divided by the square root of the sample size. In this case, the standard error is $1,600 / sqrt(64) = $200.

Next, we need to calculate the z-score, which measures the number of standard deviations an observation is from the mean. The z-score can be calculated using the formula: z = (sample mean - population mean) / standard error. In this case, the z-score is (3000 - 2600) / 200 = 2.

Finally, we can use a standard normal distribution table or a calculator to find the probability of a z-score greater than 2. The probability is approximately 0.0228 or 2.28%.

Therefore, the probability that a random sample of 64 students from the school will have an average salary of more than $3,000 is approximately 2.28%.

The mass of the object a piece of sheet metal is deformed into a shape modeled by the surface is 238.43

The mass of the object, we need to integrate the planar density function over the surface S.

The surface S is defined as {(x, y, z) | x² + y² = 22.5, 2 < z < 10}, we can set up the integral as follows:

Mass = ∬S p(x, y, z) dS

Since the surface S is a portion of a cylinder, we can use cylindrical coordinates to express the integral. Let's express the planar density function in terms of the cylindrical coordinates:

p(x, y, z) = 0.1(1 + 22/25)

= 0.1(47/25)

= 0.0944 grams per square centimeter

In cylindrical coordinates, we have:

x = rcosθ

y = rsinθ

z = z

The limits for the cylindrical coordinates are: 2 < z < 10 0 < θ < 2π r varies depending on z. From the equation x² + y² = 22.5, we can solve for r:

r² = 22.5

r = √22.5

Now, we can express the integral in cylindrical coordinates:

Mass = ∫∫∫ p(r, θ, z) r dr dθ dz

Limits of integration: 2 < z < 10 0 < θ < 2π 0 < r < √22.5

Integrating the density function p(r, θ, z) = 0.0944 over the given limits, we can calculate the mass:

Mass = ∫(2 to 10) ∫(0 to 2π) ∫(0 to √22.5) 0.0944 r dr dθ dz

In this case, we have: f(x, y) = 5x + 5y

f_x = 5

f_y = 5

We also have the region R, which is the triangle with vertices (0, 0), (4,0), and (0, 4). To set up the integral, we need to find the limits of integration for x and y. Since the triangle has vertices at (0, 0), (4,0), and (0, 4), we can set up the integral as follows:

A = ∫∫√(1 + (f_x)^2 + (f_y)^2) dA

A = ∫_0^4 ∫_0^(4-x) √(1 + 5^2 + 5^2) dy dx

A = ∫_0^4 √51(4-x) dx

A = √51 ∫_0^4 (4-x)^(1/2) dx. To evaluate this integral, we can use the substitution u = 4-x, which gives us: du = -dx

x = 0 => u = 4

x = 4 => u = 0

Substituting these limits and the expression for x in terms of u into the integral, we get: A = √51 ∫_4^0 u^(1/2) (-du)

A = √51 ∫_0^4 u^(1/2) du

A = √51 (2/3) u^(3/2) |_0^4

A = (2/3) √51 (4^(3/2) - 0)

A = (2/3) √51 (8)
