The questions are already answered I just want someone to look through it and double check thanks. (there are 3 questions).

The curve C is the triangle with vertices at (3, 0, 0), (0, 3, 0) and (0, 0, 3), oriented counterclockwise as viewed from above. If F(x, y, z) = (8x + 1), 4y + 2', 7z + 17) then: (Suggestion: Use the Curl Theorem.) and The velocity field of a fluid is given by: v(x, y, z) = (x z, 1 - Aryz, x2? ) The surface S is the part of the cone 4x2 + 923 = (y - 6)' where 0
