**Population Growth** The population *P* (in millions) of Brazil from 1990 through 2013 can be modeled by

*t* represents the year, with *t =* 0 corresponding to 1990. *(Source: U.S. Census Bureau)*

(a) Evaluate *P* for *t =* 0, 4, 8, 12, 16, 20, and 23. Explain these values.

(b) Find *dP/dt* and explain its meaning in this situation.

(c) Evaluate *dP/dt* for the same values as in part (a). Explain your results.

**(a)**
