Chapter 11.4, Problem 44E

(a)

To determine

To calculate: The value of $f\left(15\right)$ and interpret, if $f\left(t\right)=1.51e^{0.347t}$ gives the number of bicycle lanes in the Unites States where $t=9$ corresponds to the year $2009$.

(b)

To determine

To calculate: The value of $f\text{'}\left(15\right)$ if $f\left(t\right)=1.51e^{0.347t}$ gives the number of bicycle lanes in the Unites States where $t=9$ corresponds to the year $2009$.
