Solve the problem.
-The decay of $984 \mathrm { mg }$ of an isotope is given by $\mathrm { A } ( \mathrm { t } ) = 984 \mathrm { e } ^ { - 0.014 \mathrm { t } }$, where $\mathrm { t }$ is time in years. Find the amount left after 12 years.
A) 416
B) 970
C) 820
D) 832

Question

Quizplus · Accepted Answer

To find the amount left after 12 years, substitute $t = 12$ into the given formula: $A(12) = 984e^{-0.014 \times 12}$. Calculating this gives approximately 832 mg.
