The populations P (in millions) of Zambia from 1950 through 2013 can be modeled by P 2.490276t, where t is the time in years, with t-0 corresponding to 1950. t (a) Find the populations (in million people) in 1950, 1970, 1990, 2000, 2010, and 2012. (Round your answers to two decimal places.) 1950 1970 1990 2000 2010 2012 million people million people million people million people million people million people (b) Explain why the change in population from 1950 to 1970 is not the same as the change in population from 1990 to 2000 The population is increasing exponentially· , not linea rly ã (c) Use the model to estimate the population (in million people) in 2025. (Round your answer to two decimal places.) million people
