Quigley Inc. is considering two financial plans for the coming year. Management expects sales to be $300,000, operating costs to be $265,000, assets (which is equal to its total invested capital) to be $200,000, and its tax rate to be 25%. Under Plan A it would finance the firm using 25% debt and 75% common equity. The interest rate on the debt would be 8.8%, but under a contract with existing bondholders the TIE ratio would have to be maintained at or above 3.2. Under Plan B, the maximum debt that met the TIE constraint would be employed. Assuming that sales, operating costs, assets, total invested capital, the interest rate, and the tax rate would all remain constant, by how much would the ROE change in response to the change in the capital structure? Do not round your intermediate calculations.

Answer:

the coordinates of point P are (15, 19 + 3 sqrt(3)).

Step-by-step explanation:

Let's first find the center of the circle, which is (h, k). From the given information, we know that h = 12 and k = 16.

Next, we need to find the coordinates of the point P. We can do this using the formula for finding a point on a circle given its center and angle:

x = h + r cos(theta)

y = k + r sin(theta)

where r is the radius of the circle and theta is the angle between the horizontal axis and the line connecting the center of the circle to the point P.

Substituting the given values, we have:

x = 12 + 6 cos(pi/3)

y = 16 + 6 sin(pi/3)

Evaluating the trigonometric functions, we get:

x = 12 + 6 (1/2) = 15

y = 16 + 6 (sqrt(3)/2) = 19 + 3 sqrt(3)

Therefore, the coordinates of point P are (15, 19 + 3 sqrt(3)).

The additional cost incurred in dollars when production is increased from 12 units to 15 units is -$2.28.

To find the additional cost incurred in dollars when production is increased from 12 units to 15 units, we need to calculate the difference in the marginal cost between these two production levels.

Given the marginal cost function: C′(x) = 0.12x^2 − 4x + 140

We can substitute x = 12 into the marginal cost function to find the marginal cost at 12 units:

C′(12) = 0.12(12)^2 − 4(12) + 140

C′(12) = 0.12(144) − 48 + 140

C′(12) = 17.28 − 48 + 140

C′(12) = 109.28

Similarly, we can substitute x = 15 into the marginal cost function to find the marginal cost at 15 units:

C′(15) = 0.12(15)^2 − 4(15) + 140

C′(15) = 0.12(225) − 60 + 140

C′(15) = 27 − 60 + 140

C′(15) = 107

Now, we can calculate the difference in marginal cost between 15 units and 12 units. The Additional cost wil be:

= C′(15) - C′(12)

= 107 - 109.28

= -2.28.

Answer:

B.2/3

Step-by-step explanation:

Let's work backwards from the information we have to determine which diagram Ronald drew.

We know that after Ronald ate on Tuesday, there was 1/2 of the pizza remaining. This means that he ate 1/2 of the pizza on Tuesday, since he had eaten 1/3 of the pizza on Monday.

So, if we add 1/2 and 1/3, we get:

1/2 + 1/3 = 5/6

This means that Ronald ate 5/6 of the pizza in total. We also know that he ate 1/2 of the pizza on Tuesday, so the fraction he ate on Monday was:

5/6 - 1/2 = 1/3

This confirms that Ronald ate 1/3 of the pizza on Monday.

Now, let's look at the answer choices. We need to find a diagram that represents Ronald eating 1/2 of the pizza, since that's what he ate on Tuesday. The only answer choice that represents 1/2 of the pizza shaded is B. 2/3.

Therefore, Ronald drew diagram B. 2/3.

Find x, so that 7x + 2, 5x + 7 and 2x - 1 form an arithmatic sequence

The scale ratio is therefore 1:5 miles per inch

The connection between distances on the map and their equivalent distances on the ground is expressed by the scale ratio. Here, one inch on the chart corresponds to five miles on the Earth. We must represent this connection as a fraction using the same units in order to calculate the scale ratio:

5 miles per inch.

By reducing both the numerator and denominator by one inch, we may simplify the following fraction:

1/5 of a mile per inch

The scale ratio is therefore 1:5 miles per inch. This implies that the comparable distance on the ground is 5 units long for every 1 unit of distance indicated on the map (1 inch) (5 miles).

Answer:

The chord length x is growing at a rate of 1 m/min after 2π minutes.

Step-by-step explanation:

The formula for chord length x in terms of radius r is:

[tex]\boxed{x &= 2r\sin\left(\dfrac{\theta}{2}\right)}[/tex]

where θ is the central angle subtended by the chord.

The formula for arc length s in terms of radius r is:

[tex]\boxed{s=r\theta}[/tex]

where θ is the central angle subtended by the chord.

Rearrange the formula for arc length to isolate θ, then substitute this into the the formula for chord length to create an equation for x in terms of s:

[tex]\begin{aligned}\theta=\dfrac{s}{r} \implies x &= 2r\sin\left(\dfrac{\frac{s}{r}}{2}\right)\\x&= 2r\sin\left(\dfrac{s}{2r}\right)\end{aligned}[/tex]

Given the radius is 6 m, substitute r = 6 into the equation for x:

[tex]\implies x &= 12\sin\left(\dfrac{s}{12}\right)[/tex]

Differentiate with respect to s:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}s} &= \dfrac{1}{12} \cdot 12\cos\left(\dfrac{s}{12}\right)\\\\&=\cos\left(\dfrac{s}{12}\right)\end{aligned}[/tex]

Given the arc length s is growing at a rate of 2 m/min:

[tex]\implies \dfrac{\text{d}s}{\text{d}t}=2[/tex]

Use the chain rule to create an equation for the rate of change of the chord x:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}t}&=\dfrac{\text{d}x}{\text{d}s}\times \dfrac{\text{d}s}{\text{d}t}\\\\&=\cos\left(\dfrac{s}{12}\right) \times 2\\\\&=2\cos\left(\dfrac{s}{12}\right) \end{aligned}[/tex]

Given the arc length is growing at a rate of 2 m/min:

[tex]\implies \dfrac{\text{d}s}{\text{d}t}=2[/tex]

Integrate to create an equation for s in terms of t:

[tex]\begin{aligned}\displaystyle \int 1 \; \text{d}s&=\int 2\; \text{d}t}\\\\ s&=2t+\text{C}\end{aligned}[/tex]

Given s = 0 when t = 0, this means that C = 0. Therefore:

[tex]\implies s=2t[/tex]

If t = 2π then:

[tex]\implies s=2 \cdot 2\pi = 4\pi[/tex]

Finally, substitute s = 4π into the equation to calculate the rate of change of the chord at 2π minutes:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}t}&=2\cos\left(\dfrac{4\pi}{12}\right) \\\\&=2 \cos \left(\dfrac{\pi}{3}\right)\\\\&=2 \cdot \dfrac{1}{2}\\\\&=1\end{aligned}[/tex]

Therefore, the chord length x is growing at a rate of 1 m/min after 2π minutes.

What is the area of Rectangle?

In any quadrilateral which have equal and parallel opposite sides is considered to be a rectangle. It is also called as a polygon with four sides and the four angles that are all 90 degrees each. A rectangle is a shape with only two dimensions. The product of the length and the breadth calculates its area. The length of the diagonals of any rectangle are equal in length. Thus, the length of the diagonals can be calculated easily using the Pythagoras theorem where, the diagonal is considered to be the hypotenuse.

Let r represents the radius, and b be the breadth.

Then, perimeter = 3.14*r+2r+2b = 12

For the dimension needed for the most light to enter we need to maximize the area.

Hence, area of the window : area of the semicircle + area of the rectangle

= [tex]\frac{3.14*r^2}{2} + 2rb[/tex]

Answer:

100 grandparents

200 parents

100 children

Step-by-step explanation:

Define the variables: Let g be the number of grandparents, p be the number of parents, and c be the number of children.

Use the total number of people to set up an equation: g + p + c = 400

Use the information that there were twice as many parents as grandparents to set up another equation: p = 2g

Use the information that there were 50 more children than parents to set up a third equation: c = p + 50

Substitute the second equation into the third equation to eliminate p: c = 2g + 50

Substitute the second equation into the first equation to get an equation in terms of g only: g + 2g + c = 400

Substitute the third equation into the first equation to get another equation in terms of g only: g + 2(1/2 c - 50) + c = 400

Simplify the equations and solve for g: g = 100

Use the second equation to solve for p: p = 2g = 200

Use the third equation to solve for c: c = p + 50 = 250

Therefore, there were 100 grandparents, 200 parents, and 100 children in attendance at the family reunion! :DDDD

Triangles QNR and RMQ are congruent

PQR is an isosceles triangle, by extension PQ = PR.

Considering the triangles QNR and RMQ:

Given that angle MRQ = angle NQR.

Likewise, angle RQM = angle RQN (since they are vertically opposite angles).

Consequently, angle MRQ = angle RQM + angle NQR = angle RQN + angle NQR = angle RNQ.

Hence, two pairs of angles that are equal:

angle MRQ = angle RNQ

angle RMQ = angle RQN

Also, PQ = PR, and for M and N are on PQ and PR at the same time, then, MQ = NR.

Through the angle-side-angle (ASA) congruence criterion, we can conclude that triangles QNR and RMQ are congruent.

The expected value of the distribution is 1 and the probability that a randomly selected student completes fewer than 2 bonus assignments is 0.75

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

a. To compute the expected value of the distribution, we need to multiply each possible number of completed bonus assignments by its probability and then add up the results. That is:

Expected value = (0 x 0.55) + (1 x 0.2) + (2 x 0.15) + (3 x 0.1) = 0 + 0.2 + 0.3 + 0.3 = 1.0

Therefore, the expected value of the distribution is 1.0.

b. To find the probability that a randomly selected student completes fewer than 2 bonus assignments, we need to add up the probabilities for the cases where x is 0 or 1. That is:

P(x < 2) = P(x=0) + P(x=1) = 0.55 + 0.2 = 0.75

Therefore, the probability that a randomly selected student completes fewer than 2 bonus assignments is 0.75 or 75%.

The total number of possible outcomes when flipping a coin three times is 8, since there are two possible outcomes for each flip (heads or tails).

Combination is a way of selecting items from a set where order does not matter. Combinations are written as a set of n distinct objects taken r at a time, where n is the total number of objects and r is the number of objects taken.

Of these 8 outcomes, 3 include exactly one head. These are the outcomes HHT, HTH, and THH.

The total number of possible outcomes is calculated using the formula 2ⁿ, where n represents the number of flips. In this case, n = 3, so the total number of outcomes is 2³ = 8.

To find the number of outcomes with exactly one head, we can use the formula nCr, which stands for n choose r.

This formula is used to calculate the number of combinations of r elements that can be chosen from a set of n elements.

In this case, n = 3 (the number of flips) and r = 1 (the number of heads).

Step-by-step explanation:

We know that the formula for perimeter (P) is P = 2w + 2l

Because we're told that the length (l) is 4 feet more than the width (w), our formula for length is l = w + 4

We can now substitute w + 4 for l in the perimeter formula and 28 for P.  This will allows us to first solve for the width:

[tex]28 = 2(w+4)+2w\\28=2w+8+2w\\28=4w+8\\20=4w\\5=w[/tex]

Now we can plug in 5 for w in our length formula to find the length:

[tex]l = 5 + 4\\l = 9[/tex]

We can check our solutions by plugging in 5 for w and 9 for l in the perimeter formula and check whether we get 28 as an answer:

We now have two equations with two unknowns:

[tex]x + y = 5800[/tex]

[tex]0.03x + 0.08y = 229[/tex]

We can solve for x and y by using elimination or substitution method. Here, we will use the substitution method.

Answer:

y = (5/7)x + (75/7)

Step-by-step explanation:

If you ever find yourself in a math class where you have to write the equation of a line that goes through a certain point and has a certain slope, don't panic. There is a simple formula that can help you out. It's called the point-slope form and it looks like this:

y - y1 = m (x - x1)

It may look scary, but it's actually pretty easy to use. All you have to do is plug in the values that you know and solve for the ones that you don't. For example, let's say you have a line that passes through the point (-1, 10) and has a slope of 5/7. You can use the point-slope form to write the equation of the line like this:

y - 10 = (5/7) (x - (-1))

See? That wasn't so bad. Now you can simplify the equation by distributing the 5/7 and adding 10 to both sides. You get:

y = (5/7)x + (75/7)

And that's it! You have written the equation of the line in slope-intercept form, which is another way of writing the equation of a line. You can check your answer by plugging in the values of x and y from the original point and seeing if they make the equation true. If they do, you're good to go. If not, you made a mistake somewhere and you should go back and fix it.

Congratulations! You have learned how to use the point-slope form to write the equation of a line. Now you can impress your math teacher and your friends with your skills.  Remember, with great power comes great responsibility.

x = [tex]\sqrt{2}[/tex]  (or)  x = [tex]\frac{-3\sqrt{2}}{5}[/tex]

The quadratic equation can be solved to give the value of x1 = √2 and x2 = -3√2 / 5.

To solve the quadratic equation 5x² - 2√2x - 6 = 0, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Now we have two solutions, one for the positive value and one for the negative value:

x1 = (2√2 + 8√2) / 10

x2 = (2√2 - 8√2) / 10

Simplify the solutions:

x1 = (10√2) / 10 = √2

x2 = (-6√2) / 10 = -3√2 / 5

So the solutions for the equation 5x² - 2√2x - 6 = 0 are x1 = √2 and x2 = -3√2 / 5.

The triangle with the sides 8, 11 and 12 is an acute triangle

From the question, we have the following parameters that can be used in our computation:

8, 11 and 12

Using the pythagoras theorem, we have

12² = 11² + 8²

Evaluate the exponent on the left hand side and the sum of exponents on the right hand side

144 = 185

The above equation is false

This is because 144 and 185 are not equal

However, 144 is less than 185

This means that the triangle is an acute triangle
