Congrats on making it to integrals!
Basically you need to integral your function because integral rate in respect to time = total amount.
Also your bounts are (2001-1990,2006-1990)=(11,16)
Thus we take integral like:
int(11,16)(928.5e^(0.0249x))=
(11,16)928/0.0249e^(0.0249(x))-928/0.0249e^(0.0249(x))
(You can check this by taking its derivative and seeing if you get the original function)
928/0.0249e^(0.0249(16))-928/0.0249e^(0.0249(11))=6498.1
The answer is actually 3 and 4.

lies between the two consecutive numbers 3 and 4.
I hope this helped! :))
Where are the variables for the equation?
I'm assuming you mean to list the terms of the expression. Those are mn, -2n, and +8. There are 3 terms there.
Answer:
387
Step-by-step explanation:
6(4)³ + 3(1)²
6(64) + 3(1)
384 + 3
= 387
