Not Specific Enough:
is it 4a(2-3a)-41(7a-72)-23a(64)6a-2?
6a. By the convolution theorem,

6b. Similarly,

7. Take the Laplace transform of both sides, noting that the integral is the convolution of
and
.


where
. Then
, and

We have the partial fraction decomposition,

Then we can easily compute the inverse transform to solve for f(t) :


40 - 4 = 36
average = 36/9 = 4
answer
average number of members who joined the math club is 4 per month
$430 because you divide 15,480 divided by 36 and get your answer
subtract 5 from both sides. -1.6r=-5 divide both sides by-1.6. r=-5/-1.6 simp;ify-5/1.6 to 3.125. r =3.125
