Use a parameterization to find the flux modifyingbelow integral from nothing to nothing integral from nothing to nothing with upper s bold upper f times n d sigma of bold upper f equals z squared bold i plus xj minus 2 z bold k in the outward direction (normal away from the x-axis) across the surface cut from the parabolic cylinder zequals 9 minus squared by the planes xequals0, equals1, and z equals 0.

the answer is z7+8/5

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

yes, i think so although i am not sure. this is a very strange question.
