2-2 If writing process is bothering you,

it's ok to write only correct answer in each question.

1.0. Set up the double integraioff[1r,y} over the shaded region. O ffi-rayidxdy @ ffummmwmdy O filmzwldxdy O [:fmwmdx lnmrrlct Incorrect. If we try to bound 1; between functions of I, we see that part of the region is bounded above by the circle, while the other part is bounded above by a horizontal line. This means we would have to break our integral into two. Therefore, we bound 1' between functions of 3; instead. The circle of radius 4 is described by the equation 32 + y?' = 16. Note that we are on the le'it halfofthe circle. where I is negative. 9. Evaluate the integral of f (x, y) = xy over D, where D is the triangle in the xy-plane with vertices (0, 0), (0, 3) and (3, 0). 0 0 X Incorrect Incorrect. D is a right triangle. Its hypotenuse is the line passing through (0, 3) and (3, 0), which can be written as y = 3 - x orx = 3 - y. Either order of integration can be used. In this solution, we will integrate first with respect to y. Therefore D = {(x, y) | 0
