The dollar cost of debt for Coval​ Consulting, a U.S. research​ firm, is 7.3%.

The firm faces a tax rate of 37% on all​ income, no matter where it is earned. Managers in the firm need to know its yen cost of debt because they are considering a new bond issue in Tokyo to raise money for a new investment there. The​ risk-free interest rates on dollars and yen are

r Subscript $ Baseline equals r$=5%

and r Subscript yen Baseline equals r¥=1.4%

respectively. Coval Consulting is willing to assume that capital markets are internationally integrated and that its free cash flows are uncorrelated with the​ yen-dollar spot rate. What is Coval​ Consulting's after-tax cost of debt in​ yen? ​(Hint: Start by finding the​ after-tax cost of debt in dollars and then finding the yen​ equivalent.)

The​ after-tax cost of debt in dollars is _____________%. (Round to two decimal​ places.)

Malonic acid (FW = 104.06) is a diprotic acid of the form CH2(COOH)2, with pKa1 = 2.847
and pKa2 = 5.696. Assume all solutions are ideal.
(a) If 15.000 g of malonic acid is added to 100 mL of pure water, what will the pH of the
solution be?
(b) You add 18 mL of 5 M NaOH to the solution in part (a). What will the new pH be?
(c) You then add 5.000 g of sodium malonate (Na2CH2(COO), FW = 148.025). What will
the new pH be?

A magnet slid down the inclined aluminum ramp with a constant velocity, rather than accelerating. Alluminum is not a magnetic material so there should be no magnetic attraction between the magnet and the aluminum. Explain the process that caused this to happen.

Points will be awarded yo answer with most detail and examples.

How does the trade regime present opportunities and challenges for development?

1. Explain what it means for the normal distribution to be symmetrical about the mean?

2. Why is it important to know the mean and standard deviation for a data set when applying the empirical rule?

3. If we are focused on 68% of the normal distribution, what percentage of the distribution is left in the upper tail only?

4. What value separates the 50% of the distribution from the other 50% of the distribution?

(a) Two 58 g ice cubes are dropped into 380 g of water in a thermally insulated container. If the water is initially at 22°C, and the ice comes directly from a freezer at -16°C, what is the final temperature at thermal equilibrium? (b) What is the final temperature if only one ice cube is used? The specific heat of water is 4186 J/kg·K. The specific heat of ice is 2220 J/kg·K. The latent heat of fusion is 333 kJ/kg.

Imaging Inc., a developer of radiology equipment, has stock outstanding as follows: 15,000 shares of cumulative preferred 2% stock, $140 par, and 50,000 shares of $25 par common. During its first four years of operations, the following amounts were distributed as dividends: first year, $28,200; second year, $65,800; third year, $83,300; fourth year, $110,000.

Compute the dividends per share on each class of stock for each of the four years. Round all answers to two decimal places. If no dividends are paid in a given year, enter "0".

The demand for video recorders has been estimated to be QV = 145 - 3.2Pv +7M - .95Pf -39PM, where Qv is the quantity of video recorders, PF denotes the price of video recorder film, Pm is the price of attending a movie, PV is the price of video recorders, and M is income. Based on the estimated demand equation we can conclude:

A. Video recorders are normal goods B. Video recorder are normal goods and demand for video recorders is inelastic C. The demand for video recorders is inelastic D. Video recorders are normal goods and video recorder film is a complement for video recorders A and C A and B
