Main Answer:

(a) Additional Revenue =1710

(b)Marginal Revenue =1728 at x=14

Supporting Question and Answer:

How is the additional revenue different from marginal revenue in the context of this problem?

The additional revenue refers to the increase in revenue when the quantity of rentals is changed by a specific amount, while the marginal revenue represents the rate of change in revenue with respect to the quantity of rentals. The additional revenue provides the absolute difference in revenue between two quantities, while the marginal revenue indicates the incremental change in revenue for each additional unit of rentals.

Body of the Solution:

(a) To find the additional revenue when the number of rentals is increased from 14 to 15, we need to calculate the difference in revenue between these two values.

Let's substitute x = 14 into the revenue equation to find the revenue at x = 14:

R = 2x(500 + 34x - x^2)

R(14) = 2(14)(500 + 34(14) - 14^2)

=21840

Now, let's substitute x = 15 into the revenue equation to find the revenue at x = 15:

R = 2x(500 + 34x - x^2)

R(15) = 2(15)(500 + 34(15) - 15^2)

=23550

To find the additional revenue, we subtract the revenue at x = 14 from the revenue at x = 15:

Additional Revenue = R(15) - R(14)=23550-21840=1710

(b) To find the marginal revenue when x = 14, we need to calculate the derivative of the revenue function with respect to x and evaluate it at x = 14.

Differentiating the revenue function with respect to x: R = 2x(500 + 34x - x^2) dR/dx = 2(500 + 34x - x^2) + 2x(34 - 2x)

To find the marginal revenue, we evaluate the derivative at x = 14: Marginal Revenue = dR/dx (at x = 14)=1728

(c) To compare the results of parts (a) and (b), we can examine the values obtained in both cases. By calculating the additional revenue and the marginal revenue, we can determine if there is a difference in the revenue change when the number of rentals increases from 14 to 15, as well as the revenue change at x = 14.

By comparing the values obtained in parts (a) and (b), we can analyze the revenue changes in absolute terms and assess the relative impact of increasing the number of rentals versus the marginal revenue at a specific value of x.

Step-by-step explanation:

Weight at 4 weeks old: 70 g

The weight increases 10 g per week.

Weight at 5 weeks old: 80 g

Percent change from 70 g to 80 g

percent change = (new amount - old amount)/(old amount) × 100%

percent change = (80 - 70)/70 × 100%

percent change = 14.3%

Weight at 5 week: 80 g

The weight increases 10 g per week.

Weight at 6 weeks: 90 g

percent change = (new amount - old amount)/(old amount) × 100%

percent change = (90 - 80)/80 × 100%

percent change = 12.5%

The percent change went from 14.3% to 12.5%.

He is incorrect. The percent change is smaller each week because the actual change is always the same, 10 g per week, but the starting weight each week is greater.

Answer: An acre is a unit of area commonly used in the United States and the United Kingdom to measure land. One acre is equal to 43,560 square feet. To convert acres to meters, you need to know the conversion factor between square feet and square meters.

1 square foot is equal to 0.092903 square meters (rounded to six decimal places). Therefore, 1 acre is equal to:

43,560 square feet x (0.092903 square meters / 1 square foot) = 4,046.86 square meters (rounded to two decimal places)

So, there are approximately 4,046.86 square meters in one acre. However, it's important to note that an acre is a unit of area, while meters are a unit of length. To convert between acres and meters, you would need to know the shape of the land being measured and use appropriate formulas to calculate length or width in meters.

Correlations describe the connections between different variables. Strong, weak, positive, or negative expressions are all possible. 1 = Causation need not always follow from correlation. A statistical measure of the linear relationship between two variables is called correlation (that is, do they change at a constant rate). Without defining cause and effect, this is a common method for illustrating straightforward connections. To illustrate the connection between two quantitative variables, statistical language employs correlation. Additionally, we consider that this connection is linear. In other words, when one variable changes by a given amount, the other variable also changes by a fixed amount, but only by one unit.

When the height is 38 cm and the base is 32 cm, the rate at which the area of the triangle changes is 10 cm²/min.

The rate at which the area of a triangle changes can be found by multiplying the rate at which the base is shrinking by the rate at which the height is increasing.

Given:

Rate of shrinking of the base = -2 cm/min

Rate of increasing of the height = 3 cm/min

Height of the triangle = 38 cm

Base of the triangle = 32 cm

To find the rate at which the area of the triangle changes, we use the formula for the area of a triangle:

Area = (1/2) * base * height

Differentiating the area formula with respect to time gives us:

dA/dt = (1/2) * (db/dt) * height + (1/2) * base * (dh/dt)

Substituting the given values, we have:

dA/dt = (1/2) * (-2) * 38 + (1/2) * 32 * 3

Simplifying, we get:

dA/dt = -38 + 48

dA/dt = 10 cm²/min

Therefore, when the height is 38 cm and the base is 32 cm, the rate at which the area of the triangle changes is 10 cm²/min.

Each friend will paint 1/4 or one-fourth of the wall's area.

Since the wall is divided into four equal sections and each friend will paint one section, we can determine the unit fraction of the wall's area that each friend will paint by considering the total number of sections.

Since the wall is rectangular, dividing it into four equal sections means each section represents 1/4 of the total area. Therefore, each friend will paint 1/4 or one-fourth of the wall's area.

To express this as a unit fraction, we can write it as 1/4.

So, each friend will paint 1/4 or one-fourth of the wall's area. This means that if we divide the wall into four equal parts, each friend's section will have an equal area of 1/4 of the total wall area.

This division ensures that each friend has an equal share of the painting task, with each one responsible for painting one-fourth or 25% of the wall's total area.

Let x = the number of 50-cent increases in the cost of a book rental.

Right now he is renting 38 books per day at $3 per rental. If he raises his price he will lose 4 rentals per increase. The money part of this is:

$3 + .5x = the price per book rental after the increase. That's how much money he will make. The money made is NOT the same thing as the number of rentals. Therefore, they are put into separate expressions.

The number of rentals is:

38 - 4x. This is the number of books he is currently renting minus the number of book rentals he will lose per price increase. Putting those 2 expressions together and multiplying them will give you the end result of this increase in price.

(3 + .5x)(38 - 4x) = 114 - 12x + 19x - 2x², or putting it in descending powers of x and combining like terms:

-2x² + 7x + 114

To calculate the Value-at-Risk (VaR) for this investment at a 99% confidence level, we need to determine the loss amount that will be exceeded with a probability of only 1% (i.e., the worst-case loss that will occur with a 1% chance).

Given that there is a 0.5% chance of a loss of $10 million and a 99.5% chance of a loss of $1 million, we can express this as:

Loss Amount | Probability

$10 million | 0.5%

$1 million | 99.5%

To calculate the VaR, we need to find the loss amount that corresponds to the 1% probability threshold. Since the loss of $10 million has a probability of 0.5%, it is less likely to occur than the 1% threshold. Therefore, we can ignore the $10 million loss in this calculation.

The loss of $1 million has a probability of 99.5%, which is higher than the 1% threshold. This means that there is a 1% chance of the loss exceeding $1 million.

Therefore, the Value-at-Risk (VaR) for this investment at a 99% confidence level is $1 million.

The Value-at-Risk (VaR) for this investment at a 99% confidence level is $1,045,000.

To calculate the Value-at-Risk (VaR) for this investment at a 99% confidence level, we need to determine the loss amount that will be exceeded with only a 1% chance.

Given that the investment has a 0.5% chance of a loss of $10 million and a 99.5% chance of a loss of $1 million, we can calculate the VaR as follows:

VaR = (Probability of Loss of $10 million * Amount of Loss of $10 million) + (Probability of Loss of $1 million * Amount of Loss of $1 million)

VaR = (0.005 * $10,000,000) + (0.995 * $1,000,000)

VaR = $50,000 + $995,000

In the Pythagorean theorem, a²+b²=c² is the formula for finding the missing side length in a right-angled triangle. This formula is useful for determining one of the missing side lengths of a right triangle if you know the other two.

However, the theorem also states that c is the length of the triangle's hypotenuse. So, if you have a right-angled triangle with all three sides provided, you may use the Pythagorean theorem to solve for any of the missing sides. You'll use the hypotenuse length as the c variable when the three sides are given, then solve for the missing side.

To apply the Pythagorean theorem, you must identify the hypotenuse, which is the side opposite the right angle. If you're given three sides, the longest side is always the hypotenuse. As a result, you can always use the Pythagorean theorem to solve for one of the shorter sides by using the hypotenuse length.

The preferred stockholders are entitled to receive their dividend of $1.60 per share, regardless of whether or not Jim Corporation was able to pay it in the previous years.

Therefore, the total dividend amount for the preferred stockholders is:

10,000 shares x $1.60 per share = $16,000

To determine how much each class of stock receives in dividends, we need to subtract the total preferred stock dividend from the total dividend amount of $550,000:

$550,000 - $16,000 = $534,000

This remaining amount is the dividend available for the common stockholders. To calculate how much each common stockholder will receive, we need to divide this amount by the total number of common shares:

$534,000 ÷ 65,000 shares = $8.22 per share

Therefore, each class of stock receives the following dividends:

Preferred stock: $16,000
Common stock: $8.22 per share

Jim Corporation's cumulative preferred stockholders receive $1.60 per share. There are 10,000 shares of preferred stock, so the total annual preferred dividend is $1.60 x 10,000 = $16,000.

Since the preferred dividends were not paid in 2013, 2014, and 2015, the company owes the preferred stockholders a total of $16,000 x 3 = $48,000 in dividends.

In 2016, the board of directors decided to pay out $550,000 in dividends. First, the preferred stockholders will receive their overdue dividends of $48,000. After paying the preferred dividends, there will be $550,000 - $48,000 = $502,000 left for distribution.

Next, the preferred stockholders will receive their 2016 dividends of $16,000, leaving $502,000 - $16,000 = $486,000 for common stockholders.

So, the preferred stock receives $48,000 (past due) + $16,000 (current) = $64,000 in dividends, and the common stock receives $486,000 in dividends.

Dividends:
Preferred stock: $64,000
Common stock: $486,000

The distance between the two planes after 4 hours is approximately 150 km.

to find out how far apart the planes are after 4 hours, we can use the concept of vectors.

Let's start by finding the positions of the two planes after 4 hours.

The first plane flies at a speed of 110 km/h in a direction of 280°. To find its position after 4 hours, we can use the formula: distance = speed × time. So, the distance traveled by the first plane is 110 km/h × 4 hours = 440 km.

To determine the position of the first plane, we need to convert the direction (280°) into components. The x-component is given by: cos(280°) × distance = cos(280°) × 440 km. The y-component is given by: sin(280°) × distance = sin(280°) × 440 km.

Similarly, for the second plane, which flies at a speed of 250 km/h in a direction of 200°, the distance traveled after 4 hours is 250 km/h × 4 hours = 1000 km. To determine its position, we need to convert the direction (200°) into components. The x-component is given by: cos(200°) × distance = cos(200°) × 1000 km. The y-component is given by: sin(200°) × distance = sin(200°) × 1000 km.

Now, let's calculate the x and y components for both planes:

For the first plane:
x-component = cos(280°) × 440 km
y-component = sin(280°) × 440 km

For the second plane:
x-component = cos(200°) × 1000 km
y-component = sin(200°) × 1000 km

the distance between the two planes, we can use the distance formula, which is given by: distance = √((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the positions of the first and second planes respectively.

Now, substitute the values we calculated into the distance formula:

distance = √((x2 - x1)^2 + (y2 - y1)^2)
distance = √((cos(200°) × 1000 km - cos(280°) × 440 km)^2 + (sin(200°) × 1000 km - sin(280°) × 440 km)^2)

After evaluating the above expression, the distance between the two planes after 4 hours is approximately 150 km.

\(\begin{cases} x = -5 &\implies x +5=0\\ x = 3 &\implies x -3=0\\ x = 3 &\implies x -3=0\\ \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{original~polynomial}{a ( x +5 )( x -3 )( x -3 ) = \stackrel{0}{y}}\hspace{5em}\textit{we also know that } \begin{cases} x=0\\ y=9 \end{cases} \\\\\\ a ( 0 +5 )( 0 -3 )( 0 -3 ) = 9\implies 45a=9\implies a=\cfrac{9}{45}\implies a=\cfrac{1}{5} \\\\[-0.35em] ~\dotfill\)

\(\cfrac{1}{5}(x+5)(x-3)^2=y\implies \cfrac{1}{5}(x+5)(x^2-6x+9)=y \\\\\\ \cfrac{1}{5}(x^3-x^2-21x+45)=y\implies {\Large \begin{array}{llll} \cfrac{x^3}{5}-\cfrac{x^2}{5}-\cfrac{21x}{5}+9=y \end{array}}\)
