A ferris wheel is 50 meters in diameter and boarded from a platform that is 1 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full
revolution in 4 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the
wheel begins to turn. Write an equation for h = f(t).
f(t) =

Solve the system by the elimination method. 2x + y - 4 = 0 2x - y - 4 = 0 when you eliminate y, what is the resulting equation? a. x = 0 b.4x = -8 c.4x = 8

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?
