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:
Answer:
225/4
Step-by-step explanation:
When you are trying to find the number to be added to a binomial of the form :
in order to make it a perfect square trinomial, all you need to do is to use the square of half of the coefficient b. That is :
.
In your case this is:
105/4
because the ratio of the perimeter of the first to second is 4/3
Answer:
THe answer is 4 because is positive
