To derive the demand **function **from the given utility function and endowment, we need to determine the optimal allocation of goods that maximizes utility. The **utility **function is U(x, y) = -e^(-x) - e^(-y), and the initial endowment is (1, 0).

To derive the demand function, we need to find the optimal allocation of goods x and y that **maximizes **the given utility function while satisfying the endowment constraint. We can start by setting up the consumer's problem as a utility maximization subject to the budget constraint. In this case, since there is no price information provided, we assume the goods are not priced and the consumer can freely allocate them.

The consumer's problem can be stated as follows:

Maximize U(x, y) = -e^(-x) - e^(-y) subject to x + y = 1

To solve this problem, we can use the Lagrangian method. We construct the **Lagrangian function **L(x, y, λ) = -e^(-x) - e^(-y) + λ(1 - x - y), where λ is the Lagrange multiplier.

Taking partial derivatives of L with respect to x, y, and λ, and setting them equal to zero, we can find the values of x, y, and λ that satisfy the optimality conditions. Solving the equations, we find that x = 1/2, y = 1/2, and λ = 1. These values represent the optimal allocation of goods that maximizes utility given the endowment.

Therefore, the demand function derived from the utility function and endowment is x = 1/2 and y = 1/2. This indicates that the consumer will allocate half of the endowment to each good, resulting in an equal **distribution**.

A firm has the option between producing a product and purchasing it from a supplier. Assume the purchase cost per item is $ 1, the carrying cost per unit is $ 0.3, the ordering cost is 40 minutes of the wage of the accountant, and the hourly wage rate is $ 30. Assume also that the manufacturing cost per unit is $0.97, and the setup cost is $ 100. Annual demand is deterministic at a level of 40,000 per year, and the production rate is 50,000 per year. (1) Find out the EOQ for this firm. Find out the cycle time in years. (2) Find out the optimal production lot size. Find out the cycle time in years Find out the length of the production run in years. Find out how long the machines are idle per cycle. (3) Compare the total cost of the EOQ model and that of the production lot size model. Should the firm make or buy?

The firm should make the** product **rather than buying it from the supplier.

Producing a product involves certain costs such as manufacturing cost per unit and setup cost, while **purchasing** the product incurs costs such as the purchase cost per item and carrying cost per unit. In order to determine whether the firm should make or buy, we can compare the total costs associated with each option.

First, let's **calculate** the Economic Order Quantity (EOQ) using the following formula:

EOQ = sqrt((2 * annual demand * ordering cost) / carrying cost)

Substituting the given values, we get:

EOQ = sqrt((2 * 40,000 * (40/60) * 30) / 0.3) = 2,449.49

The EOQ represents the optimal production lot size that minimizes the total cost. With an EOQ of 2,449.49, the firm should produce this quantity in each production run.

Next, we can calculate the cycle time in years, which represents the time between consecutive **production** runs. Since the annual demand is 40,000 units and the production rate is 50,000 units per year, the cycle time is given by:

Cycle Time = Annual Demand / Production Rate = 40,000 / 50,000 = 0.8 years

This means that the firm should have a production run every 0.8 years.

To determine the **length** of the production run, we divide the EOQ by the production rate:

Length of Production Run = EOQ / Production Rate = 2,449.49 / 50,000 = 0.0489 years

Thus, the length of each production run is approximately 0.0489 years.

During each production cycle, the **machines** are idle for the remaining time, which can be calculated as:

Idle Time per Cycle = Cycle Time - Length of Production Run = 0.8 - 0.0489 = 0.7511 years

Therefore, the machines are idle for approximately 0.7511 years per production cycle.

Comparing the total costs of the **EOQ** model and the production lot size model will help us determine whether the firm should make or buy. By calculating the respective total costs and comparing them, we can make a decision.

The absolute maximum value of the function f(x) = 3x² + 6x - 5 over the interval [3, -2] is 40, and the absolute minimum value is -5.To find the absolute **maximum** and minimum values of the function f(x) = 3x² + 6x - 5

over the **interval** [3, -2], we can follow these steps:

1. Evaluate the **function** at the critical points and endpoints within the interval [3, -2].

2. Find the critical points by taking the derivative of the function and setting it equal to zero, then solving for x.

3. Evaluate the function at the **endpoints** of the interval.

4. Compare the **values** obtained in steps 1, 2, and 3 to determine the absolute maximum and minimum.

Let's proceed with these steps:

Step 1: Evaluate the function at the critical points and endpoints.

- Evaluate f(3) = 3(3)² + 6(3) - 5 = 27 + 18 - 5 = 40

- Evaluate f(-2) = 3(-2)² + 6(-2) - 5 = 12 - 12 - 5 = -5

Step 2: Find the critical points.

To find the critical points, we need to take the derivative of f(x) and set it equal to zero:

f'(x) = 6x + 6

6x + 6 = 0

6x = -6

x = -1

Step 3: Evaluate the function at the endpoints.

- Evaluate f(3) = 40 (from step 1)

Step 4: Compare the values.

- Absolute maximum value: f(3) = 40

- Absolute minimum value: f(-2) = -5

Therefore, the absolute maximum value of the **function** f(x) = 3x² + 6x - 5 over the interval [3, -2] is 40, and the absolute minimum value is -5.

(b) Use baplace trasformation technique to sidue the initial 52-4 solve Nale problem below у"-4у e3t

y (0) = 0

y'(o) = 0·

(a) To find the** inverse Laplace transform **of the function 45/(s² - 4), we first factor the **denominator **as (s - 2)(s + 2).

Using **partial fraction decomposition**, we can express the function as A/(s - 2) + B/(s + 2), where A and B are constants. By equating the numerators, we get 45 = A(s + 2) + B(s - 2). Simplifying this equation, we find A = 9 and B = 9. Therefore, the inverse Laplace transform of 45/(s² - 4) is 9e^(2t) + 9e^(-2t).

(b) Using the Laplace transformation technique to solve the given initial value problem y'' - 4y = e^(3t), y(0) = 0, y'(0) = 0, we start by taking the Laplace transform of the **differential equation**. Applying the Laplace transform to each term, we get s²Y(s) - sy(0) - y'(0) - 4Y(s) = 1/(s - 3). Since y(0) = 0 and y'(0) = 0, we can simplify the equation to (s² - 4)Y(s) = 1/(s - 3). Next, we solve for Y(s) by dividing both sides by (s² - 4), which gives Y(s) = 1/((s - 3)(s + 2)). To find the inverse Laplace transform, we need to decompose the expression into **partial fractions**. After performing partial fraction decomposition, we obtain Y(s) = 1/(5(s - 3)) - 1/(5(s + 2)). Taking the inverse Laplace transform of each term, we get y(t) = (1/5)e^(3t) - (1/5)e^(-2t).

Therefore, the solution to the **initial value problem** y'' - 4y = e^(3t), y(0) = 0, y'(0) = 0 is y(t) = (1/5)e^(3t) - (1/5)e^(-2t).

Determine the inverse Laplace transform of

G(s)=11s−8s2−2s+2

The inverse **Laplace transform** of G(s) = (11s - 8s^2 - 2s + 2) is g(t) = (11/8) - (3/4)e^(t/2) + (5/8)e^t. This is derived by decomposing G(s) into partial **fractions** and applying inverse Laplace transform.

To find the inverse Laplace transform, we can decompose the expression G(s) into partial fractions. The first step is to factorize the **denominator**: 8s^2 - 2s - 2 = (4s + 2)(2s - 1). Then, we express G(s) as a sum of partial fractions: G(s) = A/(4s + 2) + B/(2s - 1). Next, we find the values of A and B by equating the **numerators**: 11s - 8s^2 - 2s + 2 = A(2s - 1) + B(4s + 2).

Solving the **equation** above, we find A = 5/8 and B = -3/4. Now, we can apply the inverse Laplace transform to each term of the partial fraction decomposition. The inverse Laplace transform of A/(4s + 2) is (5/8)e^(-t/2), and the inverse Laplace transform of B/(2s - 1) is (-3/4)e^(t/2). Combining these results, we obtain the **inverse** Laplace transform of G(s): g(t) = (11/8) - (3/4)e^(t/2) + (5/8)e^t.

This given ODE is:(2xy - 2y²e^(3x))dx + (x² - 2ye^(2x))dy = 0.To verify the exactness of the given ODE, we determine whether or not ∂Q/∂x = ∂P/∂y, where P and Q are the coefficients of dx and dy respectively, as follows: P = 2xy - 2y²e^(3x) and Q = x² - 2ye^(2x).Then, we have ∂P/∂y = 2x - 4ye^(3x) and ∂Q/∂x = 2x - 4ye^(2x).Thus, since ∂Q/∂x = ∂P/∂y, the given ODE is exact.To solve the given ODE, we have to find a **function** F(x,y) that satisfies the equation Mdx + Ndy = 0, where M and N are the **coefficients** of dx and dy respectively.

We differentiate both sides of this equation with respect to y, set it equal to Q, and then solve for g(y). We have:(d/dy)(x²y - y²e^(3x) + g(y)) = x² - 2ye^(2x)Thus, g'(y) = 0 and g(y) = C, where C is a constant.Substituting the value of g(y) in the equation above, we get:x²y - y²e^(3x) + C = 0, as the** general solution.**The given ODE is exact, so we can solve it by finding a function that satisfies the equation Mdx + Ndy = 0.

The equation for forecasting m periods in future with the Holt-Winters’ additive method is: Y_{t+m} = L_t + mT_t + S_{t-m+1+((m-1) mod m)}

Mapping f: (0, +oo) → R, defined as f(x) = x × ln(x³):

To determine if f is injective, we need to check if different** elements** in the domain can map to the same element in the codomain.

Taking the** derivative** of f, we get f'(x) = 1 + 3ln(x³).

Since the derivative is positive for all x > 0, we can conclude that f is strictly increasing.

Therefore, different elements in the domain will map to different elements in the codomain.

Hence, f is injective.

Mapping g: (0, +[infinity]) → R, defined as g(x) = x × (x + sin(7x)):

To determine if g is injective, we need to check if different elements in the domain can map to the same element in the codomain.

Since the function includes the sine function, it can introduce periodic behavior and potentially map different elements to the same element.

Therefore, g is not injective.

Mapping h: (0, +[infinity]) → R, defined as h(x) = x × x + sin(7x):

Part 1

a. The value of this bond if it paid interest annually would be

$.

(Round to the nearest cent.)

The value of this bond, if it paid **interest annually**, would be $850.78.

In order to calculate the value of the **bond**, we need to use the present value formula for a bond. The present value of a bond is the sum of the present values of its future cash flows, which include both the periodic coupon payments and the final principal payment at maturity.

To calculate the present value of the annual coupon payments, we can use the formula:

PV = C × (1 - (1 + r)⁻ⁿ) / r,

where PV is the present value, C is the **coupon payment**, r is the required yield to maturity, and n is the number of periods.

In this case, the coupon payment is $120 ($1,000 par value × 12% coupon rate), the required yield to **maturity** is 14% (0.14), and the number of periods is 13. Plugging these values into the formula, we get:

PV = $120 × (1 - (1 + 0.14)⁻¹³) / 0.14

≈ $850.78.

Therefore, the value of this bond, if it paid interest annually, would be approximately $850.78.

Few hours before a flight departure there are 25 people connected to the website of the airline to buy tickets for that flight. The number of tickets purchased by a customer of that company through the website is a random variable with mean 1.4 and standard deviation 1.0. Assuming there are 40 seats available on that flight, what is the probability that the 25 customers can buy the tickets they desire?

The probability that the 25 customers can buy the tickets they desire is approximately the cumulative **probability** P(X ≤ 40).

To calculate the probability that the 25 customers can buy the tickets they desire, we need to consider the distribution of the total number of tickets purchased by these customers.

Since the number of tickets purchased by each customer follows a random variable with mean 1.4 and standard deviation 1.0, we can approximate the total number of tickets purchased by the 25 **customers** using a normal distribution.

The mean of the total number of tickets purchased by the 25 customers would be 25 multiplied by the mean of individual ticket purchases, which is (25)(1.4) = 35.

The **standard deviation** of the total number of tickets purchased by the 25 customers would be the square root of 25 multiplied by the variance of individual ticket purchases, which is √(25)(1.0^2) = 5.

Q5: The function y = 1/2 sin 3(θ + 4) + 3 represents a** sinusoidal function **with amplitude and phase shift.

Amplitude: Amplitude of a function is the absolute value of the coefficient of the sine or cosine function in its equation.

Here, the amplitude of the given function

y = 1/2 sin 3(θ + 4) + 3 is 1/2.

Phase shift: The phase shift is the horizontal displacement of the graph of a function from the usual position.

Here, the phase shift of the function

y = 1/2 sin 3(θ + 4) + 3 is -4 units to the left.

**Transformation**: The function y = sin(x) is a basic trigonometric function whose amplitude is 1, phase shift is 0, and period is 2π.

The given function y = 1/2 sin 3(θ + 4) + 3 can be obtained from y = sin(x) by stretching the graph of y = sin(x) horizontally by a factor of 1/3, shifting the graph of y = sin(x) 4 units to the left, vertically stretching the graph of y = sin(x) by a factor of 1/2, and shifting the graph of y = sin(x) 3 units upward.

a) Let h be the height of the tire above the ground in cm and d be the distance traveled by the car since the tire picked up the nail.

Since the diameter of the car's tire is 60 cm, the radius of the tire is 30 cm.

Hence, the model for the height of the tire above the ground in terms of the distance the car has traveled since the tire pick up the nail is given by the formula:

h = 60 - (30² - d²)½.

b) After the car has traveled 0.5 km = 500 m, the distance traveled by the car since the tire picked up the nail is

d = 500 / π

≈ 159.15 cm

The height of the tire above the ground will be

h = 60 - (30² - d²)½

= 60 - (30² - 159.15²)½

≈ 52.6 cm

The height of the nail above the ground will be

Consider the complement of the event before computing its probability If two 8-sided dice are rolled, find the probability that neither die shows a two. (Hint: There are 64 possible results from rolling two 8-sided dice.)

The** probability** of rolling two 8-sided dice and getting no two is 49/64.

If two** 8-sided dice** are rolled, the total possible outcomes are 64.

A probability is the ratio of the number of favorable outcomes to the total number of outcomes.

To determine the probability of rolling two 8-sided dice and getting no two, it is advisable to consider the complement of the event before computing the probability.

The complement of an event is the set of outcomes that are not part of the event. So, the probability of rolling two 8-sided dice and getting no two can be computed as follows:

Step 1: Determine the probability of rolling two dice and getting a 2 on at least one of the dice.

Since there are 8 sides on each die, the probability of rolling a 2 on one die is 1/8. The probability of rolling a 2 on both dice is

(1/8) × (1/8) = 1/64.

To determine the probability of** rolling two dice **and getting a 2 on at least one of the dice, we need to find the complement of this event. The complement of rolling a 2 on at least one die is rolling no 2 on either die.

Therefore, the probability of rolling two dice and getting no 2 is:

Step 2: Determine the probability of rolling no 2 on either die.

The probability of rolling no 2 on one die is 7/8.

Determine the slope of the tangent line to f(x) = sin(5x) at x = ㅠ/4

a. -5√2/2

b. 0

c. 5√2/4

d. 5

The **slope **of the** tangent** line to the function f(x) = sin(5x) at x = π/4 is 5√2/4, which corresponds to option (c).

To find the slope of the tangent line at a given point, we need to take the **derivative** of the** function** and evaluate it at that point.

The derivative of sin(5x) with respect to x can be found using the chain rule, which states that if y = f(g(x)), then dy/dx = f'(g(x)) * g'(x).

Applying the chain rule to sin(5x), we have f'(x) = cos(5x) * d(5x)/dx = 5cos(5x).

Now, let's find the slope at x = π/4.

Plugging in π/4 into the derivative,

we get f'(π/4) = 5cos(5(π/4)) = 5cos(5π/4) = 5cos(π + π/4).

Since the cosine function has a period of 2π and cos(π + θ) = -cos(θ), we can rewrite it as -5cos(π/4). Knowing that cos(π/4) = √2/2, we have -5(√2/2) = -5√2/2.

Thus, the **slope** of the **tangent **line to f(x) = sin(5x) at x = π/4 is -5√2/2, which is equivalent to 5√2/4. Therefore, the correct answer is option (c).

He tries this for a month and compares how often employees were late under the old system to how often they were late under the new, harsher punishment system. He utilizes less than hypothesis testing and finds that at an alpha of .05 he rejects the null hypothesis. What would Scrooge McDuck most likely do?

a. Run a new analysis; this one failed to work

b. Keep punishing his employees for being late; it's not working yet but it might soon

c. Stop punishing his employees harder for being late; it isn't working

d. Keep punishing his employees when they're late; it's working

Scrooge McDuck would most likely keep punishing his **employees** when they're late; it's working.

So, the correct answer is D.

Less than **Hypothesis testing** is a statistical hypothesis test where the alternative hypothesis is formed as <, while the null hypothesis is formed as >=.

Therefore, when Scrooge McDuck utilized the less than hypothesis testing and found that at an alpha of .05 he rejects the null hypothesis, it means that the p-value obtained from the test was less than 0.05, and thus he had enough statistical evidence to **reject** the null hypothesis and accept the alternative hypothesis.

g. a K since it is a 10.

The **probability **of selecting an E.Q card (any card that is not a sword) can be determined by considering the number of E.Q cards in the deck and dividing it by the total number of cards.

To calculate this probability, we first need to determine the number of E.Q cards in a deck. Since the question does not provide **specific information **about the number of E.Q cards, we cannot provide an exact answer. However, assuming a standard deck of 52 playing cards, there are no E.Q cards in a typical deck. Therefore, the probability of selecting an E.Q card is 0.

F. The **probability **of selecting a diamond card (any card of the diamond suit) that is not a 3 can be determined by considering the number of eligible cards and dividing it by the total number of cards.

In a standard deck of 52 playing cards, there are 13 diamond cards (Ace through King). However, since we are excluding the 3 of **diamonds**, there are a total of 12 diamond cards that are not 3. Therefore, the probability of selecting a diamond card that is not a 3 can be calculated as 12 divided by 52, which simplifies to 3/13.

G. The probability of selecting a K card (any card that is a King) given that it is a 10 can be determined by **considering **the number of K cards that are 10s and dividing it by the total number of 10 cards.

In a standard deck of 52 playing cards, there are 4 K cards (one King in each suit: hearts, diamonds, clubs, and spades). Since we are interested in the probability of selecting a K card that is a 10, we need to determine the number of 10 cards in the deck. There are 4 10 cards (10 of hearts, 10 of diamonds, 10 of clubs, and 10 of spades).

If n is a prime odd integer, it cannot be expressed as a sum of three or more consecutive positive **integers**.

If n is not expressible as a sum of three or more consecutive positive integers, then n is prime.

To prove that an odd integer n > 1 is prime if and only if it is not **expressible **as a sum of three or more consecutive positive integers, we need to demonstrate both directions of the statement.

Direction 1: If an odd integer n > 1 is prime, then it is not expressible as a sum of three or more consecutive **positive **integers.

Assume that n is a prime odd integer. We want to show that it cannot be expressed as the sum of three or more consecutive positive integers.

Let's suppose that n can be **expressed **as the sum of three consecutive positive integers: n = a + (a+1) + (a+2), where a is a positive integer.

Expanding the equation, we have: n = 3a + 3.

Since n is an odd integer, it cannot be divisible by 2. However, 3a + 3 is always divisible by 3. This implies that n cannot be expressed as the sum of three consecutive positive integers.

Therefore, if n is a prime odd integer, it cannot be expressed as a sum of three or more consecutive positive integers.

Direction 2: If an odd integer n > 1 is not expressible as a sum of three or more **consecutive **positive integers, then it is prime.

Assume that n is an odd integer that cannot be expressed as a sum of three or more consecutive positive integers. We want to show that n is prime.

Suppose, for the sake of **contradiction**, that n is not prime. This means that n can be factored into two positive integers, say a and b, such that n = a * b, where 1 < a ≤ b < n.

Since n is odd, both a and b must be odd. Let's express a and b as a = 2k + 1 and b = 2l + 1, where k and l are non-negative integers.

**Substituting **into the equation n = a * b, we have: n = (2k + 1)(2l + 1).

Expanding the equation, we get: n = 4kl + 2k + 2l + 1.

Since n is odd, it cannot be divisible by 2. However, the expression 4kl + 2k + 2l + 1 is always **divisible **by 2. This contradicts our assumption that n cannot be expressed as the sum of three or more consecutive positive integers.

Therefore, if n is not expressible as a sum of three or more consecutive positive integers, then n is prime.

The demand for fleece sweaters in some towns is p = 70 - Q, where p represents price and Q represents quantity. The variable cost is 2Q and the fixed cost is 30. At present, there are two companies on the market, A and B. Company A decides on the production volume and company B adjusts its production volume (response) to that decision.

What is the production volume and price that maximizes the profits of each company? What is the combined profit of the parties? Show the calculations underlying this result.

Draw a picture and show the demand that A faces and how it determines the most efficient quantity while you show reaction B. Mark the axes of coordinate systems and intersection points with axes separately.

How does this equilibrium compare to equilibrium in the case of perfect competition in this market? Draw the competitive equilibrium on the picture in point 2.

To determine the production volume and price that maximize the profits of each company, we need to analyze the** profit functions** of both companies and find their respective** optimal quantities** and prices.

Let's go through the calculations step by step: Profit function for Company A: Company A's profit (πA) can be calculated as the difference between revenue and costs: **πA = (p - 2Q)Q - 30**. Substituting the demand equation p = 70 - Q, we have: πA = (70 - Q - 2Q)Q - 30. πA = (70 - 3Q)Q - 30. Expanding and simplifying: πA = 70Q - 3Q² - 30. Profit function for Company B:Company B's profit (πB) is dependent on Company A's production volume. Let's assume Company B adjusts its production to match Company A's quantity. Therefore, the profit function for Company B is:** πB = (70 - Q - 2Q)Q - 30**. πB = (70 - 3Q)Q - 30. Maximizing profit for Company A:To find the quantity that maximizes Company A's profit, we take the derivative of πA with respect to Q and set it equal to zero:**dπA/dQ = 70 - 6Q = 0. **Solving for Q: 70 - 6Q = 0. 6Q = 70. Q = 70/6. Q = 11.67

Maximizing profit for Company B: Since Company B adjusts its production to match Company A's quantity, its optimal quantity will also be 11.67.Price determination:To find the price corresponding to the optimal quantity, we substitute Q = 11.67 into the demand equation:p = 70 - Q. p = 70 - 11.67 . p ≈ 58.33. Combined profit of the parties: To calculate the combined profit of the two companies, we sum up their individual profits at the optimal quantity:π_combined = **πA + πB**. Substituting the optimal quantity into the profit functions: π_combined = (**7011.67 - 3(11.67)² - 30) + (7011.67 - 3(11.67)² - 30)**

To draw a picture of the **demand curve** and show how Company A determines the most efficient quantity while Company B reacts, we can plot the demand curve with price on the **y-axis** and quantity on the x-axis. The point of intersection with the axes represents the equilibrium point. In the case of perfect competition in the market, the equilibrium would occur where the supply curve intersects the demand curve. The competitive equilibrium can be represented by the point where the supply curve, which would represent the marginal cost curve, intersects the demand curve on the graph. Note: Without specific information on the supply or marginal cost curve, it is not possible to accurately draw the competitive** equilibrium** point on the graph.

Find the area A of the shaded region of the cardioid r = 21 ~ 21 cos (0). The cardioid (Express numbers in exact form: Use symbolic notation and fractions where needed:)

To find the area A of the shaded region of the **cardioid** r = 21 - 21cos(θ), we need to set up the integral to integrate the area enclosed by the curve.

The cardioid is symmetric about the x-axis, so we can integrate from θ = 0 to θ = π, and then multiply the result by 2 to get the total area.

The area element dA in polar **coordinates** is given by dA = (1/2) r^2 dθ. Substituting r = 21 - 21cos(θ), we have dA = (1/2) (21 - 21cos(θ))^2 dθ.

Therefore, the integral to find the area is:

A = 2 ∫[0 to π] (1/2) (21 - 21cos(θ))^2 dθ.

Simplifying the expression inside the integral:

A = ∫[0 to π] (21 - 21cos(θ))^2 dθ.

Expanding and simplifying further:

A = ∫[0 to π] (441 - 882cos(θ) + 441cos^2(θ)) dθ.

Now, we can **integrate** term by term:

A = ∫[0 to π] 441 dθ - ∫[0 to π] 882cos(θ) dθ + ∫[0 to π] 441cos^2(θ) dθ.

The integral of 441 dθ is 441θ evaluated from 0 to π, which gives 441π - 0 = 441π.

The integral of cos(θ) dθ is sin(θ) evaluated from 0 to π, which gives sin(π) - sin(0) = 0.

To evaluate the integral of cos^2(θ) dθ, we can use the double **angle** formula: cos^2(θ) = (1 + cos(2θ))/2.

∫ cos^2(θ) dθ = ∫ (1 + cos(2θ))/2 dθ.

Splitting the integral and integrating each term separately:

∫ (1 + cos(2θ))/2 dθ = (1/2) ∫ dθ + (1/2) ∫ cos(2θ) dθ.

The integral of dθ is θ, so we have:

(1/2) θ + (1/4) sin(2θ) evaluated from 0 to π.

Substituting the **limits**:

(1/2) π + (1/4) sin(2π) - [(1/2) 0 + (1/4) sin(2(0))] = (1/2) π.

Therefore, the area A of the shaded region is:

A = 441π - 0 + (1/2) π = (441/2)π.

In exact form, the area A of the shaded **region** of the cardioid r = 21 - 21cos(θ) is (441/2)π.

Using polar coordinates, evaluate the integral region 1 ≤ x² + y² ≤ 64. 1₁²² sin(x² + y²)dA where R is the

To evaluate the **integral** ∫∫R₁ sin(x² + y²) dA, where R is the region defined by 1 ≤ x² + y² ≤ 64, we can use **polar coordinates**.

In **polar coordinates**, x = rcosθ and y = rsinθ, where r represents the distance from the origin and θ is the angle between the positive **x-axis** and the line connecting the origin to the point.

To express the given region in **polar coordinates**, we need to determine the **range** of r and θ that satisfy the **inequality** 1 ≤ x² + y² ≤ 64.

The inequality 1 ≤ x² + y² can be written as 1 ≤ r². Taking the **square root**, we get r ≥ 1.

The **inequality** x² + y² ≤ 64 can be written as r² ≤ 64. Taking the **square root**, we obtain r ≤ 8.

**Combining** both inequalities, we have 1 ≤ r ≤ 8.

To express the integral in **polar coordinates**, we need to change the element of **area** dA. In polar coordinates, dA = r dr dθ.

Now, the **integral** becomes ∫∫R₁ sin(x² + y²) dA = ∫∫R₁ sin(r²) r dr dθ.

To evaluate this integral over the region R, we integrate with respect to r first, then with respect to θ. The **limits of integration** for r are 1 to 8, and the limits of integration for θ are 0 to 2π, covering the entire region R.

In summary, to evaluate the **integral** ∫∫R₁ sin(x² + y²) dA over the region R defined by 1 ≤ x² + y² ≤ 64, we convert to polar coordinates. The integral becomes ∫∫R₁ sin(r²) r dr dθ, with the **limits of integration** for r as 1 to 8 and the limits of integration for θ as 0 to 2π.

Is there a linear filter W that satisfies the following two properties? (1) W leaves linear trends invariant. (2) All seasonalities of period length 4 (and only those) are eliminated. If yes, specify W. If no, justify why such a moving average does not exist. Note: A moving average that eliminates seasonalities of length 4 will, of course, also eliminate seasonalities of length 2. However, this property is not important here and does not need to be considered. It is only necessary to ensure that the moving average does not, for example, also eliminate seasonalities of length 3, 5, 8 or others.
