The machine repair model may often be used to approximate the behavior of a computer’s CPU (central processing unit). Suppose that 20 terminals (assumed to always be busy) feed the CPU. After the CPU responds to a user, he or she takes an average of 80 seconds before sending another request to the CPU (this is called the think time). The CPU takes an average of 2 seconds to respond to any request.

On the average, how long will a user have to wait before the CPU acts on his or her request? How will your answer change if there are 30 terminals? 40 terminals?

Of course, you must make appropriate assumptions about exponentiality to answer this question

You have been hired as an expert witness in a court case involving an automobile accident. The accident involved car A of mass 1430 kg which crashed into stationary car B of mass 1160 kg .The driver of car A applied his brakes 15 m before he skidded and crashed into car B. After the collision, car A slid 18 m while car B slid 30 m.The coefficient of kinetic friction between the locked wheels and the road was measured to be 0.60. Show that the driver of car A was exceeding the 55-mi/h (90 km/h) speed limit before applying the brakes. Find this speed

You are a financial analyst at a major business valuation firm. You are analyzing how a change in beta will impact the present value of corporation that is considering an investment project. The project requires an initial investment of $100 million and will generate a perpetuity of after tax cash of $15 million every year forever. The project’s beta is 2. Assume that risk free rate is 6% and the return on the market is 8%. Please answer the following questions.

What is the net present value of the project ?

What is the highest possible discount rate for the project before its NPV becomes negative ?

What is the highest possible beta estimate for the project before its NPV becomes negative ?

A cylinder with a volume of 10 liters contains 1.32 kg of carbon dioxide at a pressure of 75 atm. The carbon dioxide has a molecular weight of 0.044 kg / mol and its molecule has 2 free rotations.

a) Calculate the gas temperature in the cylinder. If the temperature is increased by 50 degrees, how much will the pressure increase? Do not take into account the thermal expansion of the cylinder

b) Calculate the number of molecules in the cylinder and the internal energy of the carbon dioxide before heating

c) Calculate the internal energy of the gas after heating and the amount of heat given to the gas.

(d) Determine the mass of the carbon dioxide molecule and its average rate before heating

A manufacturer of fabricated metal products has acquired a new plasma table for $37,000. It is projected that the acquisition of this equipment will increase revenue by $10,000 per year. Operating costs for the machine will average $2,600 per year. The machine will be depreciated using the MACRS method, with a recovery period of 7 years. The company uses an after-tax MARR rate of 10% and has an effective tax rate of 30%.

2. Now, suppose that the duration of the project is six years and that an estimate of the value of the equipment cannot be obtained from the marketplace.

2.2. Find the before-tax PW, IRR and discounted payback period (before-tax MARR = 10%). Can the acquisition be economically justified? Why or why not?

Stanton inc is considering the purchase of a new machine that'll reduce before tax cash operations cost by 5000 annually and increase sales by 10000 annually. It will use marcs method to deprecate machine and will sell machine at the end of 5th yr for 15000 before tax. Marginal rate 21% and uses 10% cost of capital . Machine has marcs class life of 5 yrs. Dep rates 20% 32% 19.2% 11.52% 11.52% and 5.76 for years 1-6. Machine cost 600000. What is after tax cash flow of new machine t=4 (cf4)? T=5 (cf5) and npv of new machine?
