In t years, the population of a certain city grows from 500,000 to a size P given by P(t) = 500,000 + 4000t². dP a) Find the growth rate, dt b) Find the population after 20 yr. c) Find the growth rate at t = 20. d) Explain the meaning of the answer to part (c). dP a)- b) The population after 20 yr is (Simplify your answer.) c) The growth rate at t = 20 is. (Simplify your answer.) d) What is the meaning of the answer to part (c)? O A. The growth rate tells the average growth from time t= 0 and t=20. OB. The growth rate tells the rate at which the population is growing at time t=20. OC. The growth rate tells the rate at which the population is growing at time t=20-1. O D. The growth rate tells the difference between the rate of growth at the beginning of t= 0 and t=20.
