We're looking for the two values being subtracted here. One of these values is easy to find:
<span>g(1) = ∫f(t)dt = 0</span><span>
since taking the integral over an interval of length 0 is 0.
The other value we find by taking a Left Riemann Sum, which means that we divide the interval [1,15] into the intervals listed above and find the area of rectangles over those regions:
</span><span>Each integral breaks down like so:
(3-1)*f(1)=4
(6-3)*f(3)=9
(10-6)*f(6)=16
(15-10)*f(10)=10.
So, the sum of all these integrals is 39, which means g(15)=39.
Then, g(15)-g(1)=39-0=39.

I hope my answer has come to your help. God bless and have a nice day ahead!
It should take approximately 27 days using the water at an average of. 450 gallons per day
Answer:
12f+49g
Step-by-step explanation:

A
5/4 is 12.5
12.5/2 is 6.25
6.25*4 is 25
Okie, so you have 2 polynomials separated by a plus sign. If there were a number in front of the polynomial, you would need to factor, as well as if there was a negative sign. But there is just an addition sign so you just add as you would normally.
5x + 9 + 3x - 2 = 8x +7
I hope this helps :-)
