Chapter 8, Problem 31CRE

(a)

To determine

To calculate: A model of the form $P\left(t\right)=P_0{e}^{kt}$ to represent the pollution $P\left(t\right)$ for a time t years since $2000$; where the population of a city was $320,000$ in the year $2000$ and by $2012$, the population reached $360,800$.

(b)

To determine

To calculate: The population in the year $2015$ if trend continues where the population of a city was $320,000$ in the year $2000$ and by $2012$, the population reached $360,800$.

(c)

To determine

To calculate: The amount of time for the population to reach $400,000$ if trend continues where the population of a city was $320,000$ in the year $2000$ and by $2012$, the population reached $360,800$.
