APCALC-DEG1G5

Let $H(t)=\frac{a}{t^{40}}-b \cdot e^t$ where $a$ and $b$ are both fixed constants.

What is $H'(t)$?

A

$H'(t)=-\cfrac{40a}{t^{41}}-b \cdot t \cdot e^{t-1}$

B

$H'(t)=-\cfrac{40a}{t^{39}}-b \cdot e^t$

C

$H'(t)=-\cfrac{40a}{t^{39}}-b \cdot t \cdot e^{t-1}$

D

$H'(t)=-\cfrac{40a}{t^{41}}-b \cdot e^t$
