Problem 6.14 Your grandfather is retiring at the end of next year. He would like to ensure that his heirs receive payments of $8,900 a year forever, starting when he retires. If he can earn 9.3 percent annually, how much does your grandfather need to invest to produce the desired cash flow? (Round answer to 2 decimal places e.g. 15.25.) Present value of investment
Please use 6.14 to show 6.15 6.14 Lemma. If n and m are relatively prime natural numbers, then ( “(a)). (º(a)) = "ca). dm dmn All the preceding lemmas allow you to finally prove your conjecture that the sum o(d) din will just equal the natural number that you started with. 6.15 Theorem. If n is a natural number, then {ød) =n. din
Please solve 6.14, problem 6.13 included for context
For the next two problems, there are N 10000 car drivers. Each gets into an accident with probability 15%. In case of an accident, the losses are distributed uniformly on 0,10. Assume independence. Problem 6.13. Find the probability that the total losses exceed 8000. Problem 6.14. Find the value at risk at the confidence level 95%.
Chapter 27, Problem 103 In the figure 1 = 6.14 V, 2 = 13.1 V, R1 = 226 Ω, and R2 = 103 Ω. What are the (a) magnitude and (b) direction of the current through resistance 1, the (c) magnitude and (d) direction of the current through resistance 2, and the (e) magnitude and (f) direction of the current through battery 2?

A spring with 58 N/m hangs vertically next to a ruler. The end of the spring is next to the 13-cm mark on the ruler. Part A If a 3.0-kg mass is now attached to the end of the spring, where will the end of the spring line up with the ruler marks? (In cm)
Problem 6.14 Humidity and Condensation Your answer is partially correct. Try again. Air at 70.0% relative humidity is cooled isobarically at 1 atm absolute from 85.0°C to 35.0°C. a.
