Culture Growth Suppose that we start at time to = 0 with a sample of 1 ,000 cells. One day later we see that the population has doubled, and some time later we notice that the population has stabilized at 1 00,000. Assume a logistic growth model. (a) What is the population after 5 days? (b) How long does it take the population to reach 50,000 cells?
