Question 5 Let the surface H in R' parametriza Tries f : R2 - R', remaining: 3 f (u, v) = (u+ 02, u, v) Marked out of Find the area of the part S of H which lies between the xy-plane, the xz-plane and the planes given by y = 4 and z = 4. 20.00 Flag A(S) question Check Question 6 Let S be the surface in R that lies on Tries remaining: 3 C = ((x, y, Z) ER3 | 22 = 81(x2+ 12) ) Marked out of and between the planes given by z = 1 and z = 9. Then the area of S is 15.00 Flag A(S) = question Check Question 7 Consider the vector field Tries F(x, y, z) = (-6x, -5z, 9y). remaining: 3 Marked out of 10.00 Evaluate the line integral F . dr, where C is the intersection curve of the paraboloid f(x, y) = 9 - x2 - y and the cylinder Flag x2 + yz = 4 oriented counterclockwise when viewed from the positive z- axis. question Answer SF . dr = Check
