Marnie drove 150 miles in 2 hours. The distance Marnie drives, , is a function of the time Marni e spends driving, . Assume Marnie was driving at a constant rate. 1. The equation that represents her distance driving as a function of the amount of time is:

2. After 4 hours, Marnie was driving for
miles.

3. After 9 hours, Marnie drove
miles.

4. If we were to plot the points from exercises 2 and 3, we would find out that the function is a
function.

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.

What is the value of x in the this question ?
