Multiple Choice

Using Green's Theorem, compute the counterclockwise circulation of F around the closed curve C.
- $\mathrm { F } = ( \mathrm { x } + 2 \mathrm { y } ) \mathbf { i } + ( 9 \mathrm { x } - 6 \mathrm { y } ) \mathbf { j } ; \mathrm { C }$ is the region bounded above by $\mathrm { y } = - 5 \mathrm { x } ^ { 2 } + 28$ and below by $\mathrm { y } = 2 \mathrm { x } ^ { 2 }$ in the first quadrant
