Evaluate ∫∫S F · dS, when F(x, y, z) = 4yi + 4xj + 4zk and S is the boundary of the solid region E enclosed by the paraboloid z = 36 - x2 - y2 and the plane z = 0. SOLUTION S consists of a parabolic top surface S1 and a circular bottom surface S2. Since S is a closed surface, we use the convention of positive (outward) orientation. This means that S1 is oriented upward and we can use Equation 10 with D being the projection of S1 on the xy-plane, namely, the disk x2 + y2 ≤ 1. So we have

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
