Answer:
30
Step-by-step explanation:
30
Okay the scale for this equation is each inch equals 30 miles. SO to get how many miles 4.5 inches equals to, we have to multiply 30 by 4.5, and the answer we get is 135.
I hope this helps!
4/5=24/30 and 4/6=20/30
So three easy fractions between these are 21/30=7/10, 22/30=11/15 and 23/30.
The prism of the surface area is 11200
We want to find a scalar function

such that

.
So we need to have

Integrating both sides with respect to

gives

Differentiating with respect to

gives



So we find that

By the fundamental theorem of calculus, we then know the line integral depends only on the values of

at the endpoints of the path. Therefore
