The surface

can be parameterized by

where

and

. Then the surface integral can be computed with

Answer:
B. 
Step-by-step explanation:
To find the inverse of a function/equation:
- Replace f(x) with y: y=5x+4
- Switch x and y: x=5y+4
- Solve for y: x-4=5y ->

- Write in standard inverse notation:

I hope this helps!!

Differentiating both sides of

with respect to
yields

At the point (3, 4) (so
and
), the tangent line has slope

Then the tangent line to (3, 4) has equation

Answer:
Step-by-step explanation:
100% divided by 4 is 25%
25 books were 1/4 of the books total.
the other 3/4 would be 75%
they og ordered 100 books
There are 66.666666 etc..... so if you round you get
67%
