The amount of A (in grams) of radioactive plutonium remaining in a 20 gram sample after t days is given by the formula A = 20(.5) t 140 At what rate is the plutonium decaying when t = 6 days? Answer in appropriate units. 17. A function f and its first and second derivatives are defined for all real numbers, and it is given that f(0) = 2, f’(0) = 3, and f”(0) = -1. a. Define a function g by g(x) = e kx f (x) where k is a constant. Find g’(0) and g”(0) in terms of k. Show your work. b. Define a function h by h(x) = cos(bx)f(x), where b is a constant. Find h’(x) and write an equation for the line tangent to the graph h at x= 0.
