Under certain conditions, the number of diseased cells N(t) at time t increases at a rate N'(t) = A e k, where A is the rate of increase at time 0 (in cells per day) and k is a constant. a. Suppose A = 40, and at 4 days, the cells are growing at a rate of 120 per day. Find a formula for the number of cells after t days, given that 200 cells are present at t = 0. b. Use your answer from part a to find the number of cells present after 9 days. ...... a. Find a formula for the number of cells, N(t), after t days.
