The population of a certain planet is believed to be growing according to the logistic equation. The maximum population the planet can hold is 1010. In year zero the population is 50\% of this maximum, and the rate of increase of the population is 109 per year. What is the logistic equation satisfied by the population, p. [Hint: previous question] p? =

How many years until the population reaches 90% of the maximum? [Hint: use the general solution given in the text] number of years = .How many years is it since the population was 109? number of years =
