A region in the plane is bounded by y=1/√ x, the xaxis, the line x=m, & the line x=2m where m>0. A solid is formed by revolving the region around the x-axis. The volume of this solid

a) is independent of m

b) increases as m increases

c) decreases as m increases

d) none of the above

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
