China's population in 1980 was 983 million; in 1990, it was 1,154 million. (a) Develop the mathematical model that represents China's population. (Write your model in terms of t, where t is the number of years after 1980. Let p represent China's population in millions. Round the coefficient of t to seven decimal places.)   p(t) = ?   (b) The following model represents Africa's population in millions, where t is the number of years after 1990.   p(t) = 643e0.0210939t   Use this and the model in part (a) to predict when Africa's population will exceed China's. (Round your answer to the nearest year.)   Africa's population will have exceeded China's in the year _?__.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
