For each of the following vector fields F, decide whether it is conservative or not by computing the appropriate first order partial derivatives. Type in a potentialfunction f (that is, ∇f = F) with f(0,0)=0. If it is not conservative, type N.
A. F(x, y)=(−16x+2y)i+(2x+10y) j f(x, y)=
B. F(x, y)=−8yi−7xj f(x, y)=
C. F(x, y)=(−8sin y)i+(4y−8xcosy)j f(x, y)=

(A)

(B)

But we assume is a function of alone, so there is not potential function here.

(C)

For (A) and (C), we have , which makes for both.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
