At the end of each year, $6500 is invested in an IRA earning 3% interest compounded annually. Answer parts (A) and (B) below.(A) How much will be in the account at the end of 40 years? Use the following annuity formula, where P = periodic payment, i= rate per period, n = number of payments (periods), andF = FV = future value.(1 + i)" – 1F(P,i,n) = PiThere will be $ in the account at the end of 40 years.(Simplify your answer. Do not round until the final answer. Then round to two decimal places as needed.)(B) Use graphical approximation methods to determine the rate of interest that would produce $910,000 in the account at the end of 40 years.An interest rate of approximately % will produce $910,000 in the account at the end of 40 years.(Type an integer or decimal rounded to the nearest tenth as needed.) Let x = f(p,g) be the demand function for tennis rackets and y = g(p,g) be the demand function for tennis balls, where p is the price for 1 unit oftennis rackets and g is the price for 1 unit of tennis balls. The demand functions for the two products are given such that the demand for eitherdepends on the price for both. If a decrease in demand for one product results in an increase in demand for another product, the two products aresaid to be competitive, or substitute, products. If a decrease in demand for one product results in a decrease in demand for another product,Test for Competitive andComplementary ProductsProducts APartial Derivativesand Bthe two products are complementary products. Partial derivatives can be used to test whether two products are competitive, complementary, orfq(p.q) > 0 andgp(p.q) > 0fo(p.q) <0 and9p(P.q) < 0fg(p.q) 20 and g, (p.q)<0 Neitherfo(p.q) s0 and g, (p,q) 2 0 NeitherCompetitive(substitute)neither. Use the test given in the table to the right to determine the relationship between tennis rackets and tennis balls.x = f(p.q) = 600 – 0.005p2 - 0.002g?y = g(p.q) = 900 – 0.006p² – 0.004q²Complementary.....Which of the following describes the relationship between tennis rackets and tennis balls?O A.
