find the producers' surplus if the supply function for pork bellies is given by the following. s(q)=q5/2 3q3/2 50 assume supply and demand are in equilibrium at q=9.

The Taylor series for f(x) = 1/(1-9x) near 0 is:

1 + 9x + 81x^2 + 729x^3 + ...

To find the Taylor series for f(x), we can use the formula:

f(x) = f(a) + f'(a)(x-a) + (f''(a)/2!)(x-a)^2 + (f'''(a)/3!)(x-a)^3 + ...

where f'(x) represents the first derivative of f(x), f''(x) represents the second derivative of f(x), and so on.

In this case, f(x) = 1/(1-9x), so we need to find its derivatives:

f'(x) = 9/(1-9x)^2

f''(x) = 162/(1-9x)^3

f'''(x) = 1458/(1-9x)^4

and so on.

Now we can plug in a = 0 and evaluate the derivatives at a:

f(0) = 1

f'(0) = 9

f''(0) = 162

f'''(0) = 1458

Plugging these values into the formula, we get:

f(x) = 1 + 9x + 81x^2 + 729x^3 + ...

which is the Taylor series for f(x) near 0.

We need to know the area of the ramp in order to calculate the total cost of the material. Let's assume the ramp has a length of L feet and a width of W feet. Then the area of the ramp can be calculated as:

Area = Length x Width = L x W

We don't have any specific values for L and W, but let's assume that Santiago wants to build a ramp that is 10 feet long and 3 feet wide. In that case:

Area = 10 feet x 3 feet = 30 square feet

Now we can calculate the cost of building the ramp by multiplying the area by the cost per square foot:

Cost = Area x Cost per square foot = 30 square feet x $2.20/square foot

Cost = $66

Therefore, the cost of building the ramp with a length of 10 feet and a width of 3 feet, using material that costs $2.20 per square foot, would be $66.

Answer: We can solve this problem using the standard normal distribution and standardizing the variable X.

Let Z be a standard normal variable, which is obtained by standardizing X as:

Z = (X - μ) / σ

where μ is the mean of X and σ is the standard deviation of X.

In this case, X is normal with mean μ = 3.6 and variance σ^2 = 0.01, so its standard deviation is σ = 0.1.

Then, we have:

Z = (X - 3.6) / 0.1

To find C such that P(X <= c) = 5%, we need to find the value of Z for which the cumulative distribution function (CDF) of the standard normal distribution equals 0.05. Using a standard normal table or calculator, we find that:

P(Z <= -1.645) = 0.05

Therefore:

(X - 3.6) / 0.1 = -1.645

X = -0.1645 * 0.1 + 3.6 = 3.58355

So C is approximately 3.5836.

To find C such that P(X > c) = 10%, we need to find the value of Z for which the CDF of the standard normal distribution equals 0.9. Using the same table or calculator, we find that:

P(Z > 1.28) = 0.1

Therefore:

(X - 3.6) / 0.1 = 1.28

X = 1.28 * 0.1 + 3.6 = 3.728

So C is approximately 3.728.

To find C such that P(-c < X < c) = 95%, we need to find the values of Z for which the CDF of the standard normal distribution equals 0.025 and 0.975, respectively. Using the same table or calculator, we find that:

P(Z < -1.96) = 0.025 and P(Z < 1.96) = 0.975

Therefore:

(X - 3.6) / 0.1 = -1.96 and (X - 3.6) / 0.1 = 1.96

Solving for X in each equation, we get:

X = -0.196 * 0.1 + 3.6 = 3.5804 and X = 1.96 * 0.1 + 3.6 = 3.836

So the interval (-c, c) is approximately (-0.216, 3.836).

Answer:

This is not possible, since probabilities cannot be negative. Therefore, there is no value of e that satisfies the given condition

Step-by-step explanation:

We can use the standard normal distribution to solve this problem by standardizing X to Z as follows:

Z = (X - μ) / σ = (X - 3.6) / 0.1

Then, we can use the standard normal distribution table or calculator to find the values of Z that correspond to the given probabilities.

P(X <= c) = P(Z <= (c - 3.6) / 0.1) = 0.05

Using a standard normal distribution table or calculator, we can find that the Z-score corresponding to the 5th percentile is -1.645. Therefore, we have:

(c - 3.6) / 0.1 = -1.645

Solving for c, we get:

c = 3.6 - 1.645 * 0.1 = 3.4355

So, the value of c such that P(X <= c) = 5% is approximately 3.4355.

Similarly, we can find the value of d such that P(X > d) = 10%. This is equivalent to finding the value of c such that P(X <= c) = 90%. Using the same approach as above, we have:

(d - 3.6) / 0.1 = 1.28 (the Z-score corresponding to the 90th percentile)

Solving for d, we get:

d = 3.6 + 1.28 * 0.1 = 3.728

So, the value of d such that P(X > d) = 10% is approximately 3.728.

Finally, we can find the value of e such that P(-e < X < e) = 90%. This is equivalent to finding the values of c and d such that P(X <= c) - P(X <= d) = 0.9. Using the values we found above, we have:

P(X <= c) - P(X <= d) = 0.05 - 0.1 = -0.05

This is not possible, since probabilities cannot be negative. Therefore, there is no value of e that satisfies the given condition

The slope of the line tangent to the polar curve r=2sec2θ at the point θ=3π is Infinity that is the tangent to the curve in that point is perpendicular to X axis.

The given polar equation of the curve is, r = 2sec 2θ.

So the parametrized equations are:

x = r cosθ = 2sec2θcosθ

y = r sinθ = 2sec2θsinθ

differentiating with respect to 'θ' we get,

dx/dθ = 2 [sec2θ(-sinθ) + cosθ(sec2θtan2θ*2)] = 4cosθsec2θtan2θ - 2sec2θsinθ

dy/dθ = 2 [sec2θcosθ + sinθ(sec2θtan2θ*2)] = 4 sinθsec2θtan2θ + 2sec2θcosθ

So now,

dy/dx = (dy/dθ)/(dx/dθ) = (4 sinθsec2θtan2θ + 2sec2θcosθ)/(4cosθsec2θtan2θ - 2sec2θsinθ) = (2sinθtan2θ + cosθ)/(2cosθtan2θ - sinθ)

The slope of the curve is

= the value dy/dx at θ=3π

= {(2sinθtan2θ + cosθ)/(2cosθtan2θ - sinθ)} at θ=3π

= (2sin(3π)tan(6π) + cos(3π))/(2cos(3π)tan(6π) - sin(3π))

= (-1)/(0)

The rental company charges $10 for insurance and an additional $3 for every 5 kilometers traveled.

The rule of correspondence for the cost of renting a motorcycle from this company can be described as follows: The base cost is $10 for insurance. In addition to that, there is an additional charge of $3 for every 5 kilometers traveled. This means that for every 5 kilometers, an extra $3 is added to the total cost.

To calculate the total cost of renting the motorcycle, you would need to determine the number of kilometers you plan to travel. Then, divide that number by 5 to determine how many increments of $3 will be added. Finally, add the $10 insurance fee to the calculated amount to get the total cost.

For example, if you plan to travel 15 kilometers, you would have three increments of $3 since 15 divided by 5 is 3. So, the additional charge for distance would be $9. Adding the base insurance cost of $10, the total cost would be $19.

In summary, the cost of renting a motorcycle from this company includes a base insurance fee of $10, and an additional charge of $3 for every 5 kilometers traveled. By calculating the number of increments of $3 based on the distance, you can determine the total cost of the rental.

From central limit theorem, in a sample

a) the sampling distribution of x is normal distribution.

b) The value of P(x>91.3) is equals to the 0.093418.

From the central limit theorem, when the samples of a population are considered then these generate a normal distribution of their own. The sample size must be equal to or higher than 30 in order for the central limit theorem to be true. We have a simple random sample obtained from population with the Sample size, n = 36

Population is skewed right with population mean, µ= 87

Standard deviations, σ = 24

We have to determine the sampling distribution of x.

a) As we see sample size, n = 36 > 30, so the sampling distribution is normal distribution.

b) Using the test statistic value for normal distribution, [tex]z= \frac{ x - \mu }{\frac{\sigma}{\sqrt{n}}} [/tex]. Here, x = 91.3, µ= 87, σ = 24, n = 36. Now, the probability value is, P(x>91.3)

= [tex]P( \frac{ x - \mu }{\frac{\sigma}{\sqrt{n}}} < \frac{ 91.3 - 87 }{\frac{24}{\sqrt{36}}}) [/tex]

To find the PDF of Z=X+Y, we can use the convolution of probability density functions. Let fX(x) and fY(y) be the PDFs of X and Y, respectively. Then, the PDF of Z is:

fZ(z) = ∫fX(x)fY(z−x)dx

Since X and Y are exponentially distributed, we have:

fX(x) = λe^−λx for x > 0

fY(y) = μe^−μy for y > 0

Substituting these expressions into the convolution formula, we obtain:

fZ(z) = ∫λe^−λx μe^−μ(z−x) dx

= λμe^−μz ∫e^−(λ−μ)x dx

= λμe^−μz / (λ−μ) [1−e^(−(λ−μ)z)]

Thus, the PDF of Z is:

fZ(z) = { λμe^−μz / (λ−μ) [1−e^(−(λ−μ)z)] } for z > 0

To find the PDF of U=X−Y, we can use the change of variables technique. Let g(u,v) be the joint PDF of U and V=X. Then, we have:

g(u,v) = fX(v)fY(v−u)

Substituting the expressions for fX and fY, we get:

g(u,v) = λμe^−λve^−μ(v−u) for u < v

The PDF of U is obtained by integrating out V:

fU(u) = ∫g(u,v)dv

= ∫_u^∞ λμe^−λve^−μ(v−u) dv

= λμe^−μu ∫_0^∞ e^−(λ+μ)v dv

= λμe^−μu / (λ+μ) for all u

The lake 1 the widths, in feet, of a small lake were measured at 40 foot intervals. The area of the lake is approximately 50,000 square feet.

Find out the area of the lake, we need to use the width measurements that were taken at 40-foot intervals.

We can assume that the lake is roughly rectangular in shape, with each width measurement representing the width of the lake at that particular point.

To get an estimate of the area, we can calculate the average width of the lake by adding up all the width measurements and dividing by the total number of measurements.
For example, if there were 5 width measurements taken at intervals of 40 feet, we would add up all the measurements and divide by 5 to get the average width.

Let's say the measurements were 100 ft, 120 ft, 90 ft, 110 ft, and 80 ft. We would add these numbers together (100+120+90+110+80 = 500) and divide by 5 to get an average width of 100 feet.
Once we have the average width, we can estimate the length of the lake by using our best judgement based on the shape and size of the lake.

Let's say we estimate the length to be 500 feet. To calculate the area, we would multiply the length by the width:
Area = length x width
Area = 500 ft x 100 ft
Area = 50,000 square feet
So our estimate of the area of the lake is approximately 50,000 square feet.

The probability that five rolls of a fair die will show exactly two threes using binomial distribution is 0.1612.

The binomial distribution can be used to calculate the probability of a specific number of successes in a fixed number of independent trials. In this case, the probability of rolling a three on a single die is 1/6, and the probability of not rolling a three is 5/6.

Let X be the number of threes rolled in five rolls of the die. Then, X follows a binomial distribution with parameters n=5 and p=1/6. The probability of exactly two threes is given by the binomial probability formula:

P(X = 2) = (5 choose 2) * (1/6)^2 * (5/6)^3 = 0.1612

where (5 choose 2) = 5! / (2! * 3!) = 10 is the number of ways to choose 2 rolls out of 5. Therefore, the probability that five rolls of a fair die will show exactly two threes using binomial distribution is 0.1612.

We have the following system of differential equations:

x' = x - 3y

y' = 3x + 7y

Substitution Method:

From the first equation, we have x' + 3y = x, which we can substitute into the second equation for x:

y' = 3(x' + 3y) + 7y

Simplifying, we get:

y' = 3x' + 16y

Now we have two first-order differential equations:

x' = x - 3y

y' = 3x' + 16y

We can solve for x in the first equation and substitute into the second equation:

x = x' + 3y

y' = 3(x' + 3y) + 16y

y' = 3x' + 25y

Now we have a single second-order differential equation for y:

y'' - 3y' - 25y = 0

The characteristic equation is:

r^2 - 3r - 25 = 0

Solving for r, we get:

r = (3 ± sqrt(89)i) / 2

The general solution for y is:

y = c1*e^(3t/2)cos((sqrt(89)/2)t) + c2e^(3t/2)*sin((sqrt(89)/2)t)

To find x, we can substitute this solution for y into the first equation and solve for x:

x' = x - 3(c1*e^(3t/2)cos((sqrt(89)/2)t) + c2e^(3t/2)*sin((sqrt(89)/2)t))

x' - x = -3c1*e^(3t/2)cos((sqrt(89)/2)t) - 3c2e^(3t/2)*sin((sqrt(89)/2)t)

This is a first-order linear differential equation that can be solved using an integrating factor:

IF = e^(-t)

Multiplying both sides by IF, we get:

(e^(-t)x)' = -3c1e^tcos((sqrt(89)/2)t) - 3c2e^t*sin((sqrt(89)/2)t)

Integrating both sides with respect to t, we get:

e^(-t)x = -3c1int(e^tcos((sqrt(89)/2)t) dt) - 3c2int(e^t*sin((sqrt(89)/2)t) dt) + C

Using integration by parts, we can solve the integrals on the right-hand side:

int(e^tcos((sqrt(89)/2)t) dt) = (e^t/2)(cos((sqrt(89)/2)t) + (sqrt(89)/2)*sin((sqrt(89)/2)t)) + C1

int(e^tsin((sqrt(89)/2)t) dt) = (e^t/2)(sin((sqrt(89)/2)t) - (sqrt(89)/2)*cos((sqrt(89)/2)t)) + C2

Substituting these integrals back into the equation for x, we get:

x = -3c1*(e^(3t/2)/2)(cos((sqrt(89)/2)t) + (sqrt(89)/2)sin((sqrt(89)/2)t)) - 3c2(e^(3t/2)/2)(sin((sqrt(89)/2)t) - (sqrt(89)/2)*cos((sqrt(89)/2)t)) + C

Substitution Method:

x' = x - 3y ...(1)

y' = 3x + 7y ...(2)

To solve this system using the substitution method, we can solve one equation for one variable and substitute it into the other equation.

From equation (1), we can rearrange it to solve for x:

x = x' + 3y ...(3)

Substituting equation (3) into equation (2), we get:

y' = 3(x' + 3y) + 7y

y' = 3x' + 16y ...(4)

Now, we have a new system of differential equations:

x' = x - 3y ...(3)

y' = 3x' + 16y ...(4)

We can now solve equations (3) and (4) simultaneously using standard techniques, such as separation of variables or integrating factors, to find the solutions for x and y.

Operator Method:

The operator method involves representing the system of differential equations using matrix notation and finding the eigenvalues and eigenvectors of the coefficient matrix.

Let's represent the system as a matrix equation:

X' = AX

where X = [x, y]^T is the vector of variables, and A is the coefficient matrix given by:

A = [[1, -3], [3, 7]]

To find the eigenvalues and eigenvectors of A, we solve the characteristic equation:

det(A - λI) = 0

where I is the identity matrix and λ is the eigenvalue. By solving the characteristic equation, we can obtain the eigenvalues and corresponding eigenvectors.

Eigen-analysis Method:

The eigen-analysis method involves diagonalizing the coefficient matrix A by finding a diagonal matrix D and a matrix P such that:

A = PDP^(-1)

where D contains the eigenvalues of A on the diagonal, and P contains the corresponding eigenvectors as columns.

By diagonalizing A, we can rewrite the system of differential equations in a new coordinate system, making it easier to solve.

To solve the system using the eigen-analysis method, we need to find the eigenvalues and eigenvectors of A, and then perform the necessary matrix operations to obtain the solutions.

According to the given information, the total number of tickets sold is 80. Therefore, we have the equation:

x + y = 80 ---(1)

The total revenue generated from ticket sales is $734.00. Since each child ticket costs $5.50 and each adult ticket costs $11.50, we can express the total revenue as:

5.50x + 11.50y = 734.00 ---(2)

To solve this system of equations, we can use the substitution method or the elimination method. Let's use the elimination method:

Multiply equation (1) by 5.50 to eliminate 'x':

5.50(x + y) = 5.50(80)

5.50x + 5.50y = 440 ---(3)

Subtract equation (3) from equation (2) to eliminate 'x':

(5.50x + 11.50y) - (5.50x + 5.50y) = 734.00 - 440

6.00y = 294

y = 49

Substitute the value of y back into equation (1) to find x:

x + 49 = 80

x = 80 - 49

To show that x and y are uncorrelated, we need to compute their indefinite integraland show that it is zero:

Cov(x, y) = E(xy) - E(x)E(y)

We can compute E(x) and E(y) as follows:

E(x) = E(cos) = ∫(cos*f( )d ) = ∫(cos(1/2π)*d ) = 0

E(y) = E(sin) = ∫(sin*f( )d ) = ∫(sin(1/2π)*d ) = 0

where f( ) is the probability density function of , which is a uniform distribution over the range (0, 2π).

Next, we compute E(xy):

E(xy) = E(cossin) = ∫(cossinf( )d ) = ∫(cossin(1/2π)*d )

Since cos*sin is an odd function, we have:

∫(cossin(1/2π)*d ) = 0

Therefore, Cov(x, y) = E(xy) - E(x)E(y) = 0 - 0*0 = 0.

Hence, x and y are uncorrelated.

To show that x and y are not independent, we need to find P(x, y) and show that it does not factorize into P(x)P(y):

P(x, y) = P(cos, sin) = P( ) = (1/2π)

The conclusion, the availability of resources such as water, food, and shelter affects the populations of organisms in an ecosystem.

In an ecosystem, the availability of resources such as water, food, and shelter have an impact on the populations of organisms living in that ecosystem. Populations are affected by the availability of resources, including abiotic and biotic factors that help support their survival.

The interaction between different populations of organisms in the ecosystem is essential, which includes plants and animals living together. In the ecosystem, the food chain is the primary interaction where organisms eat other organisms to survive.

Organisms such as herbivores feed on plants and serve as food for carnivores. The availability of food is a significant factor that determines the population of herbivores and carnivores in an ecosystem. The ecosystem also depends on the availability of water, which is vital for the survival of all organisms. Lack of water can lead to a decrease in population, especially for organisms that are unable to survive in dry environments.
Additionally, the availability of shelter is also significant in determining the population of an organism in an ecosystem.

The probability of getting a green marble is approximately 0.41

The probability of getting a green marble from a bag of 50 marbles can be estimated by combining Andre, Jada, and Noah's trials.

Andre took out a marble once and got a green marble one time. Jada took out a marble 12 times and got a green marble 5 times.

Noah took out a marble 9 times and got a green marble 3 times. The total number of times they took a marble out of the bag is 1 + 12 + 9 = 22 times.

The total number of times they got a green marble is 1 + 5 + 3 = 9 times. The probability of getting a green marble is calculated as the number of green marbles divided by the total number of marbles.

Therefore, the probability of getting a green marble from this bag is 9/22 or approximately 0.41.

Since there are 50 marbles in the bag, it is a reasonable estimate that 0.41 x 50 = 20.5 of the 50 marbles are green, although this is not guaranteed.

Hence, the probability of getting a green marble is approximately 0.41.

Rounding to three decimal places, the probability is approximately 0.007.

To find the probability that the first two adults get news from television and the third gets news from the newspaper, we need to use the multiplication rule for independent events.
The probability of selecting an adult who gets news from television on the first draw is 13/75, since there are 13 adults who get news from television out of a total of 75 adults.
Assuming the first draw is an adult who gets news from television, there are now 12 adults who get news from television out of a total of 74 adults.

So the probability of selecting another adult who gets news from television on the second draw, given that the first draw was an adult who gets news from television, is 12/74.
Assuming the first two draws are adults who get news from television, there are now 14 adults who get news from a newspaper out of a total of 73 adults.

So the probability of selecting an adult who gets news from a newspaper on the third draw, given that the first two draws were adults who get news from television, is 14/73.
Therefore, the probability that the first two adults get news from television and the third gets news from the newspaper is:
(13/75) * (12/74) * (14/73) = 0.0067

The acceleration at t=10 seconds is approximately 0.2222 m/s^2.

Using Equation 23.9 of the book, we can calculate the acceleration at t=4 seconds and t=10 seconds as follows:

At t=4 seconds:

The first-order divided difference for velocity between t=2.5 and t=6.0 is:

f[t_2, t_1] = (V(t_2) - V(t_1))/(t_2 - t_1) = (18 - 15)/(6.0 - 2.5) = 1.7143 m/s^2

The first-order divided difference for velocity between t=1.0 and t=2.5 is:

f[t_1, t_0] = (V(t_1) - V(t_0))/(t_1 - t_0) = (15 - 10)/(2.5 - 1.0) = 10 m/s^2

The second-order divided difference for velocity between t=2.5, t=6.0, and t=1.0 is:

f[t_2, t_1, t_0] = (f[t_2, t_1] - f[t_1, t_0])/(t_2 - t_0) = (1.7143 - 10)/(6.0 - 1.0) = -1.6571 m/s^2

Therefore, the acceleration at t=4 seconds is approximately -1.6571 m/s^2.

At t=10 seconds:

The first-order divided difference for velocity between t=9.0 and t=12.0 is:

f[t_2, t_1] = (V(t_2) - V(t_1))/(t_2 - t_1) = (30 - 22)/(12.0 - 9.0) = 2.6667 m/s^2

The first-order divided difference for velocity between t=6.0 and t=9.0 is:

f[t_1, t_0] = (V(t_1) - V(t_0))/(t_1 - t_0) = (22 - 18)/(9.0 - 6.0) = 1.3333 m/s^2

The second-order divided difference for velocity between t=9.0, t=12.0, and t=6.0 is:

f[t_2, t_1, t_0] = (f[t_2, t_1] - f[t_1, t_0])/(t_2 - t_0) = (2.6667 - 1.3333)/(12.0 - 6.0) = 0.2222 m/s^2

Therefore, the acceleration at t=10 seconds is approximately 0.2222 m/s^2.

Given that we need to determine how the product of 5 and 0.3 can be determined using a given number line.From the given number line, we can observe that 0.3 is located at 3 tenths on the number line, we know that 5 is a whole number.

Therefore, the product of 5 and 0.3 can be determined by multiplying 5 by the distance between 0 and 0.3 on the number line. Each tick mark on the number line represents 0.1 units. So, the distance between 0 and 0.3 is 3 tenths or 0.3 units.

Therefore, the product of 5 and 0.3 is:5 × 0.3 = 1.5.The endpoint of the arrow that starts from 0 and ends at 0.3 indicates the value 0.3 on the number line. Therefore, the endpoint of an arrow that starts from 0 and ends at the product of 5 and 0.3, which is 1.5, can be obtained by making five jumps that are each unit long. This endpoint is represented by the tick mark that is 1.5 units away from 0 on the number line.

Given that f(8) = 14, it means that the input 8 results in an output of 14. The question asks for the inverse of this function, f^-1(14), which means we need to find the input that results in an output of 14.

To do this, we need to use the fact that f^-1(f(x)) = x for any x in the domain of f(x). In other words, if we apply the inverse function to the output of f(x), we should get back the original input.

So, we can start by finding the inverse function of f(x). If y = f(x), then we have:

y = 2x - 6

x = (y + 6)/2

Therefore, the inverse function of f(x) is f^-1(x) = (x + 6)/2.

Now, we can use this inverse function to find f^-1(14):

f^-1(14) = (14 + 6)/2 = 10

Therefore, the input that results in an output of 14 for the original function f(x) is 10.

The net signed area between the curve of the function f(x) = x - 1 and the x-axis over the interval [-7, 3] is -41.

To find the net signed area between the curve of the function f(x) = x - 1 and the x-axis over the interval [-7, 3], we need to integrate the function from -7 to 3 and take into account the signed area.

The integral of f(x) = x - 1 over the interval [-7, 3] is given by:

∫[-7, 3] (x - 1) dx

Evaluating this integral, we get:

[tex]∫[-7, 3] (x - 1) dx = [1/2 * x^2 - x] [-7, 3]\\= [(1/2 * 3^2 - 3) - (1/2 * (-7)^2 - (-7))][/tex]

= [(9/2 - 3) - (49/2 + 7)]

= [9/2 - 3 - 49/2 - 7]

The length of the longer diagonal of the parallelogram is approximately 5.1 ft.

We have,

To find the length of the longer diagonal of the parallelogram, we can use the law of cosines.

The law of cosines states that in a triangle with side lengths a, b, and c, and angle C opposite side c, the following equation holds true:

c² = a² + b² - 2ab * cos(C)

In this case, we have side lengths AB = 4 ft and angle A = 30°, and we want to find the length of the longer diagonal.

Let's denote the longer diagonal as d.

Applying the law of cosines, we have:

d² = AB² + AB² - 2(AB)(AB) * cos(D)

d² = 4² + 4² - 2(4)(4) * cos(80°)

d² = 16 + 16 - 32 * cos(80°)

Using a calculator, we can calculate cos(80°) ≈ 0.1736:

d² = 16 + 16 - 32 * 0.1736

d² ≈ 16 + 16 - 5.5552

d² ≈ 26.4448

Taking the square root of both sides, we find:

d ≈ √26.4448

d ≈ 5.1427 ft (rounded to the nearest tenth)

Therefore,

The length of the longer diagonal of the parallelogram is approximately 5.1 ft.

The range of (X,Y) is the region where x+y<1 and x,y≥0. This forms a triangle with vertices at (0,0), (0,1), and (1,0).

To find c, we integrate the joint PDF over the range of (X,Y) and set it equal to 1. This gives us c=2. The marginal PDFs are found by integrating the joint PDF over the other variable.

fX(x) = ∫(0 to 1-x) (2x+1)dy = 2x + 1 - 2x² - x³, and fY(y) = ∫(0 to 1-y) (2y+1)dx = 2y + 1 - y² - 2y³.

To find P(Y<2X²), we integrate the joint PDF over the region where y<2x² and x+y<1. This gives us P(Y<2X²) = ∫(0 to 1/2) ∫(0 to √(y/2)) (2x+1) dx dy + ∫(1/2 to 1) ∫(0 to 1-y) (2x+1) dx dy = 13/24.

To verify that the conclusion of Clairaut's theorem holds for f at the point (0,π/2), we need to check that the partial derivatives of f with respect to x and y are continuous at (0,π/2) and that they are equal at this point. Since e^(π/2) is not equal to π/2, the conclusion of Clairaut's theorem does not hold for f at the point (0,π/2).

First, let's find the partial derivative of f with respect to x:
∂f/∂x = yexy sin(y)
Now, let's find the partial derivative of f with respect to y:
∂f/∂y = exy cos(y) + exy sin(y)
At the point (0,π/2), we have:
∂f/∂x = π/2
∂f/∂y = e^(π/2)
Both partial derivatives exist and are continuous at (0,π/2).
To check that they are equal at this point, we can simply plug in the values:
∂f/∂y evaluated at (0,π/2) = e^(π/2)
∂f/∂x evaluated at (0,π/2) = π/2
Since e^(π/2) is not equal to π/2, the conclusion of Clairaut's theorem does not hold for f at the point (0,π/2).
