Question 373789
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A\ =\ Pe^{rt}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ e^{rt}\ =\ \frac{A}{P}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ e^{0.425t}\ =\ \frac{1500}{300}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ e^{0.425t}\ =\ 5]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \ln(e^{0.425t})\ =\ \ln(5)]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.425t\ln(e)\ =\ \ln(5)]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ t\ =\ \frac{\ln(5)}{0.425}]


All that is left is pushing calculator buttons.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
