The populations of two countries are given for January 1, 2000, and for January 1, 2010. a. Write a function of the form P t = P 0 e k t to model each population P t (in millions) t years after January 1, 2000. b. Use the models from part (a) to approximate the population on January 1, 2020 for each country. Round to the nearest hundred thousand. c. Israel had fewer people than Switzerland in the year 2000, yet from the result of part (b), Israel would have more people in the year 2020? Why? d. Use the models from part (a) to predict the year during which each population would reach 10 million if this trend continues.
