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

Problem 6.13 Part A Draw the shear diagram for the beam. Assume that Mo 200 lb.ft, and L 20 ft. Begin by placing the lines of discontinuity. Place the appropriate function between the lines of discontinuity, ensuring the endpoints have the correct values Note Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it will appear...

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
