Match the steps to find the equation of the parabola with focus (-1, -8.75) and directrix y = - 9.25. 1. Find the distance from the focus to the point on the parabola. 2. 3 Choose a point on the parabola. 3. Use (x, y). 1 Square both sides and simplify. 4. Set the distance from focus to the point equal to the distance from directrix to the point. 5. Write the equation of the parabola. 6. Find the distance from the point on the parabola to the directrix.

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.
