Assume that the City of Rockwall sold an issue of $1,000 maturity value, tax-exempt (municipal bond), zero coupon bonds 5 years ago. The bonds had a 25-year maturity when they were issued, and the interest rate built into the issue was a nominal 10 percent, but with semiannual compounding. The bonds are now callable at a premium of 10 percent over the accrued value. What effective annual rate of return would an investor who bought the bonds when they were issued and who still owns them earn if they were called today?

1) Given a silicon p-n junction diode. Consider there are ND = 1E16 cm-3 in its conduction band while NA = 1E17 cm-3 . (i) At thermal equilibrium, calculate built-in potential (Vbi) using band diagram (no formulae). On the n-side, estimate the electron concentration and flux at q*Vbi above the conduction band. (ii) Now a forward bias VA is applied. On the n-side, estimate the electron concentration and flux at the same energy level at part (i). Hence show that the current will be exponentially dependent on the forward bias voltage.

1. Process maps (or flow charts) can only built on the value-added work activities in the process neglecting the non-value added work activities. (TRUE/FALSE)
2. Suppose that the results for an exam are normally distributed with a mean of 87 and a standard deviation of 17. Approximately 76% percentages of examinees pass the exam by the grade of 75. (TRUE/FALSE)
3. Scatter plot represents a point plotted on a two-dimensional coordinate system. (TRUE/FALSE)
4. Process capability ratio indicates whether or not the chance variability in a process is acceptable relative to the specifications. (TRUE/FALSE)

Suppose that an electricity provider would build a power plant at the cost of $50 million. Once the plant is built, it would cost the plant $0.07 per kilowatt hour of electricity that it produces. Over its lifetime, the plant is expected to generate 100 million kilowatt hours. Suppose that the regulators believe that the investors who put up capital to build the plant should be able to recoup its investment plus a 300% return throughout the life of the plant. Calculate the price per kilowatt hour that the regulators should allow the plant operators should charge.

Custom Clubs produces handmade golf clubs. The process is labor intensive. The speed at which a club can be built depends on the skill level of the individual worker.

Management has established a standard of 4 labor hours per club. The standard wage rate is $14 per hour.

During a recent month, 2,800 custom clubs were produced. Management was pleased that only 5,100 labor hours were worked, however total wages amounted to $62,500.

Compute the total variance for labor, and determine how much is related to rate and efficiency components

Soon to be famous, Texas Smokers, a locally owned business and manufacture of barbeque smokers wants to calculate its breakeven point for its business. Its Classic smoker sells for $335 with a unit variable cost of $235. The fixed cost is $57,000.

- What is the unit contribution margin ($)?

-What is the breakeven volume?

-What is the breakeven revenue?

-If 700 units built, what is the profit?

- If the price is raised by $50, what is the new breakeven volume?

- If the variable cost per unit is raised by $25, what is the new breakeven volume? Use the original selling price.

Consider the market for automobiles in the U.S. Explain how each of the following cases will affect the equilibrium quantity and equilibrium price of automobiles the U.S. auto market.

a. The stock market boomed and automobile is a normal good for a typical U.S. consumer

b. Auto insurance rates increases and wages of auto workers increases as well.

c. More and safer interstate highways are built and Ford exit the U.S. market to serve only European and African markets.

d. Nucor Corporation increase there steel production and OPEC place an embargo on the U.S.

e. The stock market crashes.

Note: The editorial should be built around ONE well-developed and well-supported idea. Do not go off tangents as it is going to disrupt the flow of the editorial and confuse the reader. You need to support the idea with statistics, examples, etc. drawn from quality finance sources. Do not use Wikipedia, Investopedia or blogs as your references. Avoid using “I,” “I think,” “In my opinion,” etc

an article in the newyork times on president obama's unsuccessful attempt to eliminate tax benefits for college savings accounts notes "in theory, tax reform is supposed to be built around cutting back preferences like these, in order to pay for some combination of lower tax rates and tax preferences aimed at people with lower incomes. the writer concludes that in practice, tax reform is difficult to enact. briefly explain why it may be difficult politically to eliminate tax preference for some groups in order to improve the efficiency of the tax code by reducing general tax rates

There is an engineering project that uses complex numbers,
electrical circuits. you need to develop a user-defined structure type and a set of operations that will make complex arithmetic virtually as straightforward as arithmetic on C’s built-in numeric types. You will need to define functions for complex I/O as well as for the basic arithmetic operations (addition, subtraction, and for finding the absolute value of a complex number).

Hint: the complex number a + bi has a real part a and an imaginary part b, where the symbol i represents 1.

|a + bi| = '( a)2+(b)2
