(a) Use the fact that the population was 250 million in 1990 (t =0) to formulate a logistic model for the US population. (Assume thecarrying capacity is 4500 million. Assume P is the population inmillions, k is the relative growth rate, and t is the time in yearssince 1990.)
P(t) = ?
(b) Determine the value of k in your model by using the fact thatthe population in 2000 was 275 million. (Round your answer to eightdecimal places.)
k =
(c) Use your model to predict the US population in the years 2100and 2200. (Round your answers to the nearest person.)
year 2100 P = ? million
year 2200 P = ? million
