Answer
Explanation:
Step1: Calculate the number of years from 1979 to 2013
The number of years (t = 2013 - 1979=34)
Step2: Substitute (t = 34) into the growth function (V(t)=205e^{0.145t})
[ \begin{align*} V(34)&=205e^{0.145\times34}\ &=205e^{4.93}\ \end{align*} ] We know that (e^{4.93}\approx138.87) (using a calculator for the exponential function)
Step3: Calculate the value of (V(34))
[ \begin{align*} V(34)&=205\times138.87\ &=205\times(138 + 0.87)\ &=205\times138+205\times0.87\ &=28290+178.35\ &=28468.35 \end{align*} ]
Answer:
(28468)
