Set up a double integral for calculating the flux of the vector field f⃗ (x, y,z)=xi⃗ +yj⃗ through the open-ended circular cylinder of radius 8 and height 9 with its base on the xy-plane and centered about the positive z-axis, oriented away from the z-axis. if necessary, enter θ as theta.

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
