An investor invests $500. The investment pays $100 at the end of year 2, $200 at the end of year 3 and $300 at the end of year 4.

Calculate the net present value (NPV) of the investment using interest preference rate of 5.7%.

----------------------------------------------

I got

v = 1/1.12

So would it just be NPV = -500 + 100(v)^2 + 200v^3 + 300v^4?

(a) Prove the following claim: in every simple graph G on at least two vertices, we can always find two distinct vertices v,w such that deg(v) = deg(w).

(b) Prove the following claim: if G is a simple connected graph in which the degree of every vertex is even, then we can delete any edge from G and it will still be connected.

4. For the Japanese wind lens turbine, the effect of the shroud is to reduce the downstream pressure, e.g., in the rotor wake, say by ?P. Show by modifying the Betz limit, how power production can actually be greater than the Betz limit. Your power production should be a function of a = v4/V. Assume v4 and S4 are known. Get it as close as you can. In the process, recognize that the wind speed at the rotor plane and even in the wake region are greater than the measured wind speed in free stream. Consider the stream tube below. Follow the same methodology used to derive the Betz limit.

(i). Relate all mass flows at each section to the downstream mass flow rate at section 4.

(ii). Apply conservation of mass to relate section areas to S4.

(iii). Apply conservation of linear momentum applied to and Bernouli’s equation to calculate the drag force, D, across the rotor plan.

(iv). Equate these expressions for Drag.

(v). Use conservation of energy to estimate power production as a function of a = v¬4 / V.

Please answer the following questions about the pictured circuit.

A circuit with two batteries, and two loops (three loops if you count the outer loop). The central section has resistor of 5-ohms. The left loop has a 10-V battery with its positive terminal facing up and 5-ohm resistor. The right loop has a 15_V battery with its positive terminal facing down and the third 5-ohm resistor. The current through the 15.0-V battery is I15 = 8 3 A = 2.667 A. What is the current (magnitude and direction) through the 10.0-V battery? (Please enter your numerical answer in decimal form; WebAssign will not accept a fraction.) I10 =__________ A, up/down

through the 10.0-V battery What is the current (magnitude and direction) through the central 5.00-Ω resistor in the circuit (the 5.00-Ω resistor that runs vertically)? (Please enter your numerical answer in decimal form; WebAssign will not accept a fraction.)

Question: Business Law (Topic Consideration)

1.) In the landmark case, Hamer v. Sidway, what were the promises exchanged between the uncle and the nephew? Did the nephew live up to his promise? If so, why didn’t he receive anything from the uncle? What did the nephew give up in exchange for his uncle’s promise? According to the court, why was this sufficient? If this case were to occur today, would the outcome be the same? Why or why not?

2. Read the “You Be The Judge” section of the chapter (Kim v. Son). If you were the judge, how would you rule? Why? Explain.

3. In the Landmark Case, Alaska Packers’ Assoc. v. Domenico, why didn’t the court enforce the APA’s agreement to pay the workers double the original contract amount? What was the legal reason?

4. Briefly explain, what is an accord and satisfaction? In Henches v. Taylor, did Taylor’s check create an accord and satisfaction? Why or why not? What should Henches have done in this case if he didn’t want to create an accord and satisfaction?
