Evaluate ˚ E

4xy dV , where E is the solid that lies above the paraboloid

z = 2x

2 + 2y

2 − 7 and below the plane z = 1.

An object is translated by (x + 4, y - 2). if one point in the image has the coordinates (5, -3), what would be the coordinates of its pre-image? (9, -5) (1, -5) (9, -1) (1, -1)
