The population of Canada P t (in millions) since January 1, 1900, can be approximated by P t = 55.1 1 + 9.6 e − 0.02515 t where t is the number of years since January 1, 1900. a. Evaluate P 0 and interpret its meaning in the context of this problem. b. Use the function to approximate the Canadian population on January 1, 2015. Round to the nearest tenth of a million? c. Use the function to approximate the Canadian population on January 1, 2040. d. From the model, during which year would the Canadian population reach 45 million? e. What value will the term 9.6 e 0.02515 t approach as t → ∞ ? f. Determine the limiting value of P t .
