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′ = 0.4p(1-(p/10^10)) how many years until the population reaches 90% of the maximum? [hint: use the general solution given in the text] number of years = -(ln(1/9))/0.4 how many years is it since the population was 109? number of years =
