Based on the U.S. Census population projections for 2016 to 2060, the projected Asian population (in millions) can be modeled by the exponential function A(t) = 14.8311.01592t, where t = 0 corresponds to 2000 and 16 ≤ t ≤ 60.
(a) Use A to estimate the average rate of change in the Asian population from 2020 to 2025.
(b) Estimate the instantaneous rate of change in the Asian population in 2020.
