We know that Assets=Liabilities+Equity. If company increases the debt level , how can affect it to the ROE. Debt affects the Equity and the ROE?

1)When the three blocks below are released from rest, they accelerate with a magnitude of 0.500m/s2. Block 1 has mass M, block 2 has 2M, and block 3 has 2M. What is the coefficient of kinetic friction

2)A block of mass m is held stationary on a ramp by the frictional force on it from the ramp. A force ?,directed up the ramp, is then applied to the block and gradually increased in magnitude from zero. During the increase, what happens to the direction and magnitude of the frictional force on the block?

3)The figure below shows an initially stationary block of mass m = 2.00 kg on a floor. A force of magnitude 10.0 N is then applied at upward angle θ = 20°. What is the magnitude of the acceleration of the block across the floor if (a) μs = 0.600 and μk = 0.500 and (b) μs = 0.400 and μk = 0.300?

Prime Mortgage Company sanctions a loan application for a 30 year mortgage loan for
US$100,000. The interest rate on the loan is 12% per annum and the borrower is required to
make equated monthly payments to repay the loan in 30 years (360 months). If the market
rate of interest goes down to 9% per annum, is the loan still worth US$100,000? Why? Why
not? (5 points)

b) If the corn farmer in the example above harvests 60,000 bushels, what amount will he
receive? What if he had not hedged his position? If the corn farmer in the example is able to
harvest only 40,000 bushels and the price per bushel rises to US$3.90 due to short supply of
corn, will his exposure be completely hedged? Why? Why not? Support your answer with
calculations. (5 points)

Write a function hitRate(A, B) to return the percentage of elements in array A that match the elements with the same index in array B. A and B are 1darrays or 2darrays of the same shape. Sample: if X = np.array([1, 3, 5, 8]); Y = np.array([2, 1, 3, 8]), then hitRate(X, Y) returns 0.25. in python program

Kolby’s Korndogs is looking at a new sausage system with an installed cost of $665,000. This cost will be depreciated straight-line to zero over the project’s 5-year life, at the end of which the sausage system can be scrapped for $87,000. The sausage system will save the firm $187,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $39,000. If the tax rate is 22 percent and the discount rate is 10 percent, what is the NPV of this project?

we are going to thoroughly discuss the business drivers for using Windows Server and how it enables the business to be more efficient and effective (and therefore more successful and profitable). But first we have to understand what exactly Windows Server is. Let's start this discussion by defining what server actually means, what features are included in Windows Server, and how it is packaged and sold by Microsoft to different customers. After this, we'll get into the business requirements and the details on how it satisfies these requirements.

According to an airline, flights on a certain route are NOT on time 15% of the time. Suppose 10 flights are randomly selected and the number of NOT on time flights is recorded. Find the probability of the following question.

A) At least 3 flights are not on time.

B) At the most 8 flights are on time.

C) In between 6 and 9 flights are on time.

1. Explain how the business planning process is one of revision. Explain two clear examples of your own (not those in the textbook) showing how your calculations in the financial section of the business plan, may force you to go back and change elements in previous sections of the plan.

The use of a business case to obtain funding for an information security investment is MOST effective when the business case:

A. relates information security policies and standards into business requirements
B. relates the investment to the organization's strategic plan.
C. realigns information security objectives to organizational strategy.
D. articulates management's intent and information security directives in clear language.

Correct Answer: B????? or C????? or others (of course...)

______________________

Note

■ Some good websites claim that the correct answer is B ("relates the investment to the organization's strategic plan").

■ Others good websites claim that the correct answer is C ("realigns information security objectives to organizational strategy").

■ Why B and not C? Why C and not B?

Many thanks!

I have gotten a Year 0 Cash Flow of -2,550,000
Year 1 CF of 937,064.23
Year 2 CF of 859,691.95
Year 3 CF of 1,108,430.80
And an NPV 355,186.94

My assignment says that the Year 0 CF and the NPV are correct, but all of the other Cash Flows are incorrect. But the sum (NPV) is correct, so I'm not sure what I'm doing wrong.

2. Change all of the numbers in the data area of your worksheet so that it looks like this:

If your formulas are correct, you should get the correct answers to the following questions.

(a) What is the break-even in dollar sales?

(b) What is the margin of safety percentage?

(c) What is the degree of operating leverage? (Round your answer to 2 decimal places.)

3. Using the degree of operating leverage and without changing anything in your worksheet, calculate the percentage change in net operating income if unit sales increase by 20%.

4. Confirm your calculations in Requirement 3 above by increasing the unit sales in your worksheet by 20% so that the Data area looks like this:

A

B

C

1

2

3

4

5

6

7

(a) What is net operating income? (Negative amount should be indicated by a minus sign.)

(b) By what percentage did the net operating income increase?

5. Thad Morgan, a motorcycle enthusiast, has been exploring the possibility of relaunching the Western Hombre brand of cycle that was popular in the 1930s. The retro-look cycle would be sold for $13,000 and at that price, Thad estimates 200 units would be sold each year. The variable cost to produce and sell the cycles would be $9,100 per unit. The annual fixed cost would be $390,000.

a. What is the break-even in unit sales?

b. What is the margin of safety in dollars?

c. What is the degree of operating leverage? (Round your answer to 2 decimal places.)

Thad is worried about the selling price. Rumors are circulating that other retro brands of cycles may be revived. If so, the selling price for the Western Hombre would have to be reduced to $10,500 to compete effectively. In that event, Thad would also reduce fixed expenses to $363,000 by reducing advertising expenses, but he still hopes to sell 200 units per year.

d. What would the net operating income be in this situation? (Negative amount should be indicated by a minus sign.)
