Suppose parametric equations for the line segment between (4, 1) and (6, -5) have the form: If the parametric curve starts at (4, 1) when t = 0 and ends at (6, -5) at t = 1, then find a, b, c, and d. d = Note: You can earn partial credit on this problem. What is the volume of the solid obtained by rotating the region bounded by y = z , z = 0 and y = 4 about the line y = 4? 1. The integral expressing the volume rising the shell method is: O A. None of these B. 27 (4 - y) Vy dy c. 27 (4 - y) Vy dy D. 27 yvy dy E. 27 yvy dy 2. The integral expressing the volume using the washer method is: OA. T Jo (4- z2)2dx OB. T Jo (42 - (z2)2) dx OC. None of these OD. T. So (4 - x2)2dx OE. TT J2(42 - (x2)2) dx Stop shari
