t nt Use the compound interest formulas. A : P [t + H] and A : Pen, to solve the following problem, Find the accumulated value of an investment of 320,000 for 7 years at an interest rate off} 5% if the money is a. compounded semiannually; b. compounded monthly; c. compounded continuously a. What is the accumulated value: itthe money is compounded semiannually? 3 (Round your answer to the nearest cent) b. What is the accumulated value, itthe money is compounded monthly? 5 (Round your answer to the nearest cent) c. What is the accumulated value, if the money is compounded continuously? 5 (Round your answer to the nearest cent) 90 1+2705'0122" answer means in practical terms. models the percentage. x) of people x years old with a certain disease. Use this function and a calculator with an 3" key to evaluate f(84) and describe what this The function f(x) : f(84) m % (Round to one decimal place) In practical terms' this means the following. About \"/0 of eyeariolds have the disease. \fFind f(g(x)) and g(f(x)) and determine whether the pair of functions f and g are inverses of each other. X-7 f(x) = 7x +7 and g(x) = 7 a. f(g(x)) (Simplify your answer.) b. g(f(x) ) : (Simplify your answer.) C. O f and g are inverses of each other. O f and g are not inverses of each other
