The Number of Reports of a Certain Virus Has Increased $$\mathrm { r } ( \mathrm { t } ) = 142 \mathrm { e } ^ { 0.004 \mathrm { t } }$$

Multiple Choice

The number of reports of a certain virus has increased exponentially since year 0. The number of cases can be approximated using the function $$\mathrm { r } ( \mathrm { t } ) = 142 \mathrm { e } ^ { 0.004 \mathrm { t } }$$ , where t is the number of years since year 0. Estimate the
Number of cases in year 40.

A) 125 cases
B) 167 cases
