Solve the problem.dy/dt = ky + f(t) is a population model where y is the population at time t and f(t) is some function to describe the net effect on the population. Assume k = 0.02 and when t = 0. Solve the differential equation of y when f(t) = -18t.
A. y = -900t + 45,000 - 35,000e-0.02t B. y = 900t + 45,000 - 35,000e0.02t C. y = -900t - 45,000 - 35,000e0.02t D. y = 900t + 45,000 - 35,000e-0.02t
