Suppose in a Study of a Prarie Dog Town It $\mathrm { P } ( \mathrm { t } ) = 1000 + 500 \cos \left( \frac { 2 \pi \mathrm { t } } { 12 } \right)$

Short Answer

Suppose in a study of a prarie dog town it is discovered that the number of prarie dogs at any time t is given by $\mathrm { P } ( \mathrm { t } ) = 1000 + 500 \cos \left( \frac { 2 \pi \mathrm { t } } { 12 } \right)$ , where t is measured in months from July 1, 1990. What is the average number of prarie dogs living in the town from July 1, 1990 to July 1, 1992?
