a) A chemical manufacturer processes two chemicals, Arkon and Zenon, in varying proportions to produce three products, A, B, and C. He wishes to produce at least 150 units of A, 200 units of B, and 60 units of C. Each ton of Arkon yields 3 of A, 5 of B and 3 of C. Each ton of Zenon yields 5 of A, 5 of B and 1 of C.

i. If Arkon cost Ghc 40 per ton and Zenon Ghc 50 per ton, advise the manufacturer how to minimize cost.

ii. What is the dual of the minimizing LP problem?

I would like a clear understanding of where the values come from to complete this chart. I have seen a couple of answers that do not clearly explain how the missing values are generated (Formulas).

Given the year end prices of the following stocks, estimate the standard deviation of the returns of a portfolio of 30% AAA and 70% BBB. Enter your answer as a percent without the % sign. Round your final answer to two decimals.

C++ and leave comments explaining. Thank you

You are given two STL lists X and P where n P is already in sorted order. Write a valid C++ function

printPositions(X,P) that prints the elements in X specified by P. For example, if P = 0, 3, 7, 8, the elements in positions 0 (head of the list), 3, 7, and 8 in

X are printed. You may use only the public STL container operations. Also specify the running time of your algorithm using Big-Oh notation.

Hint: You may wish to use iterators while keeping track of the position of items being iterated through.

Marathon petroleum distribution company manages 600 gas stations in Michigan. Each gas station typically has four underground storage tanks (UGST), three for gasoline and one for diesel. The UGST develop leaks sometimes due to corrosion or changes in soil conditions. Based on historical data, Marathon estimates that the probability that a given UGST develops a leak during a given year is 0.002 for gasoline storage tanks and higher at 0.003 for diesel storage tanks potentially due to higher density of diesel and higher sulfur content. Marathon also estimates that an average leaking tank results in $10,000 in repair costs, $5000 worth lost fuel and $50,000 in clean up costs. Further, disruption to the gas station operations during repairs to the leaking tank, results in lost sales of $100,000 on which the gas station would have earned a pretax profit of $20,000.

An insurance company offers an insurance policy that would pay for repair costs, lost fuel costs and clean up costs (but not for business interruption and lost sales) in the case a UGST develops a leak. The insurance premium is $150 per UGST/year.

Alternatively, Tank Repairs Incorporated has developed a new technology of spray coating the insides of the UGSTs with a special self-sealing polymer, which would reduce the probability of leakage to 0.0005 per year/tank. However, the coating has to be done every year when the tanks are emptied for cleaning and inspection. Tank Repairs Inc. offers to coat the UGSTs managed by Marathon at the rate of $140/tank. Each time a tank is coated, it results in incremental lost sales of $200 on which Marathon would have earned a profit of $40.

What should Marathon do? Show all your intermediate steps and calculations clearly and state your assumptions.

Scenario: Susan is a 65-year-old school nurse who has recently retired from an elementary school. She is beginning to feel rather lonely now that she is no longer working. She is a widow with adult children living out of the area. Her children have suggested that she may want to move to their city and be closer to her grandchildren. She has been avoiding these discussions with her family and tells them all is fine. Moving seems like a major upheaval to her. Although she has been in fair health physically, at her last visit to the health care provider, she had lost 10 pounds and is just below her desired weight. See the link to the Overview of the Nursing Process document to assist with this assignment. Initial Discussion Post: Select a developmental theory presented in this module and apply it to the scenario above. Use the chosen theory to address the following: Explain her behavior. State two (2) priority nursing concerns and related nursing interventions for her.

1. Consider the statements below and solve

a. A project has an initial cost of $35,000, expected net cash inflows of $8,000 per year for 7 years, and a cost of capital of 11%. What is the project's discounted payback period? (Hint: Begin by constructing a time line.) Do not round intermediate calculations. Round your answer to two decimal places.

b. A project has an initial cost of $65,000, expected net cash inflows of $13,000 per year for 8 years, and a cost of capital of 12%. What is the project's payback period? Round your answer to two decimal places.

c. A project has an initial cost of $55,000, expected net cash inflows of $11,000 per year for 9 years, and a cost of capital of 8%. What is the project's PI? (Hint: Begin by constructing a time line.) Do not round intermediate calculations. Round your answer to two decimal places.

d. A project has an initial cost of $55,000, expected net cash inflows of $11,000 per year for 8 years, and a cost of capital of 8%. What is the project's NPV? (Hint: Begin by constructing a time line.) Do not round intermediate calculations. Round your answer to the nearest cent.

Consider two bonds, one issued in euros in Germany, and one issued in dollars in the US.

Assume that both government securities are one-year bonds – paying the face value of the bond

one year from now. The exchange rate, E, stands at 0.75 euros per dollar.

The face values and prices on the two bonds are given by:

US:
Face Value: $10,000 Price: $9,615.38

Germany:
Face Value: $10,000 euros : 9,433.96 euros

a.Compute the nominal interest rate on the bonds.

b. Compute the expected exchange rate next year consistent with uncovered interest parity.

c. If you expect the dollar to depreciate relative to the euro, which bond should you buy?

d. Assume that you are a US investor and you exchange dollars for euros and purchase the

German bond today. One year from now, it turns out that the exchange rate, E, is actually

0.72 (.72 euros buys one dollar). What is your realized rate of return in dollars compared to

the realized rate of return you would have made had you held the US bond?

Write two different integrals (one with respect to x, and one with respect to y) that express the surface area obtained by revolving the curve y = 2√ x between the points (0,0) and (1,2) about the x-axis. Calculate the easier integral.
