Answer:
-27/8
Step-by-step explanation:
Dividing fractions is the same as multipling the first fraction by the reciprocal of the second fraction (the numerator and denomiator are flipped).
= -3/4 x 9/2
= -27/8
You can simplify this if you want so it's not a mixed fraction
= -3 3/8
The answer is 10.4 (1 d.p)
I'm going to rewrite f(t) to make it a little easier to use the power rule:

Now just take the derivative using the power rule:

Since they ask for f'(a), we need to replace the t's with a's:
