The proportion P of doctors aware of a new treatment after t months may be modeled by the differential equation dP/dt = k(0.9-P) where k is a constant.
(a) Write the first-order linear differential equation in standard form. (b) Solve for P(t ) given that P(0) = 0 (c) Suppose that for P(6) = 0.5 . Use this to determine k. (d) Find P(18). (e) Find t so that P(t ) = 0.85 . In other words, how many months will it take for 85% of doctors to become aware of this treatment?
