The area of the parallelogram is 45 square units.

The area of the right trapezoid is 42.5 square units.

A parallelogram is a convex quadrilateral in which each pair of opposite edges are parallel and of equal length.

Area of parallelogram = base × height

= 9 × 5

= 45 square units

Area of a right trapezoid = 1/2 (a + b)h

= 1/2(10 + 7)5

= 1/2(17)5

= 1/2(85)

= 42.5 square units

Therefore, the area of the parallelogram and right trapezoid is 45 square units and 42.5 square units respectively.

(a)The amount of water in the tank is increasing.

(b)Evaluate  \(\int\limits^{18}_0(W(t) - R(t)) dt\) to get the number of gallons of water in the tank at t = 18.

(c)Solve part (b) to get the absolute minimum from the critical points.

(d)The equation can be set up as   \(\int\limits^k_{18}-R(t) dt = 1200\) and solve this equation to find the value of k.

What is the absolute value of a number?

The absolute value of a number is its distance from zero on the number line. It represents the magnitude or size of a real number without considering its sign.

To solve the given problems, we need to integrate the given rates of water flow to determine the amount of water in the tank at various times. Let's go through each part step by step:

a)To determine if the amount of water in the tank is increasing at time t = 15, we need to compare the rate of water being pumped in with the rate of water being removed.

At t = 15, the rate of water being pumped in is given by \(W(t) = 95Vt sin^2(\frac{t}{6})\) gallons per hour. The rate of water being removed is \(R(t) = 275 sin^2(\frac{1}{3})\) gallons per hour.

Evaluate both rates at t = 15 and compare them. If the rate of water being pumped in is greater than the rate of water being removed, then the amount of water in the tank is increasing. Otherwise, it is decreasing.

b) To find the number of gallons of water in the tank at time t = 18, we need to integrate the net rate of water flow from t = 0 to t = 18. The net rate of water flow is given by the difference between the rate of water being pumped in and the rate of water being removed. So the integral to find the total amount of water in the tank at t = 18 is:

\(\int\limits^{18}_0(W(t) - R(t)) dt\)

Evaluate this integral to get the number of gallons of water in the tank at t = 18.

c)To find the time t when the amount of water in the tank is at an absolute minimum, we need to find the minimum of the function that represents the total amount of water in the tank. The total amount of water in the tank is obtained by integrating the net rate of water flow over the interval [0, 18] as mentioned in part b. Find the critical points and determine the absolute minimum from those points.

d. For t > 18, no water is pumped into the tank, but water continues to be removed at the rate R(t) until the tank becomes empty. To find the value of k, we need to set up an equation involving an integral expression that represents the remaining water in the tank after time t = 18. This equation will represent the condition for the tank to become empty.

The equation can be set up as:

\(\int\limits^k_{18}-R(t) dt = 1200\)

Here, k represents the time at which the tank becomes empty, and the integral represents the cumulative removal of water from t = 18 to t = k. Solve this equation to find the value of k.

The volume of water in the ocean is estimated to be approximately 1,332,000,000,000,000,000 liters.

The Earth's oceans cover about 71% of the planet's surface and contain a vast amount of water. To calculate the volume of water in the ocean, we need to consider the average depth and the total surface area of the oceans.

The average depth of the ocean is estimated to be around 3,800 meters. The total surface area of the oceans is approximately 361,900,000 square kilometers. By multiplying the average depth by the surface area, we can find the volume of water.

Volume = Average Depth × Surface Area

Using the given values, we have:

Volume = 3,800 meters × 361,900,000 square kilometers

To convert this volume to liters, we need to consider that 1 cubic meter is equal to 1,000 liters. Therefore, we can multiply the volume in cubic meters by 1,000 to obtain the volume in liters.

Calculating the above expression, we find that the volume of water in the ocean is approximately 1,332,000,000,000,000,000 liters. This is an estimation and may vary slightly depending on the sources and assumptions used for average depth and surface area calculations.

The presence of a negative externality causes the MSC to be higher than the MSB, which leads to the market over-producing the good. This is because producers are only taking their private costs and benefits into account, not the costs and benefits to society as a whole. The difference between the private and social optima is known as the deadweight loss. In this case, the deadweight loss is equal to the shaded triangle in the attached image.

1. This is a negative externality. We can see this by the MSC being higher than the MSB. This means that the cost to society of producing the good is higher than the benefit to society, resulting in the market over-producing the good.2. See the attached image. 3. At private decision making, we set the MSB equal to the MPC: 12-0.5Q = 2+0.5Q. Solving for Q gives Q = 8. 4. To find the socially optimal quantity, we need to set MSB equal to MSC: 12-0.5Q = 2+1.5Q.

3cos²∅ (1+tan²∅) = 3

This equation involves trigonometric functions and can be simplified using trigonometric identities.

Starting with the right-hand side of the equation, we have 3. On the left-hand side, we have the expression 3cos^2(θ)(1 + tan^2(θ)).

We can simplify the expression as follows:

cos^2(θ) = 1 - sin^2(θ)

and

tan^2(θ) = sin^2(θ) / cos^2(θ)

Substituting these identities into the expression on the left-hand side, we get:

3(1 - sin^2(θ))(1 + sin^2(θ) / (1 - sin^2(θ))

Expanding the product and simplifying, we get:

3

Thus, the equation is true and holds true for all values of θ.

To calculate the relative frequency for each discount, we need to divide the number of customers who received that discount by the total number of customers. Using the table, we can see that 100 customers received a 10% discount, 55 received a 30% discount, and 245 received a 20% discount. Dividing each of these numbers by 400, we get:

Relative frequency for a 10% discount = 100/400 = 0.25

Relative frequency for a 30% discount = 55/400 = 0.1375

Relative frequency for a 20% discount = 245/400 = 0.6125

The compound interest formula is \(A = P(1+\frac{r}{n} )^{nt}\). The variables for this formula are as follows:

To find the total amount in Karen's account after 2 years, we need to define our variables and plug them into the formula.

Solving Compound Interest

Firstly, let's identify the value of each of the variables. The original amount in the account is $20. So, P = 20. Additionally, the interest rate is 10%, which is equal to 0.1. So, r = 0.1. Since interest is compounded annually, it is compounded once a year. Thus, n = 1. Finally, we want to know the amount after 2 years, so t = 2.

Now, let's plug these values into the formula above.

This can be simplified to make the equation easier to solve.

Using this equation, we can say A = 24.20. Therefore, after 2 years, Karen will have $24.20 in her account.

1. F

In this case, q1 is halved, q2 is doubled, but the distance between the charges remains d.

So, we have:

So the force has not changed.

2. F/4

In this case, q1 and q2 are unchanged. The distance between the charges is doubled to 2d.

So, we have:

q'₁=q₁
