54. In 2011?, the population of I'i-Iexico13 was growing at 1.12% a year. Assuming that this grou-'th rate continues into the future and that t is in years since 201?, the Mexican population, P, in millions, is given by P = 125(1.0112)*. a. Predict the average population of Mexico between 201? and 2050. 13. Find the average of the population in 2017 and the predicted population in 2050. c. Explain, in terms of the concavity of the graph of P, why your ansu-'er to part (b) is larger or smaller than your answer to part (a).
