Answer:
The volume will be One-eighth times the volume.
Step-by-step explanation:
Well the formula for the volume of pyramid is,
,
We can make the base length and width 6 units and the height 6 units too.
= 72
6 * 1/2 = 3
3*3*3
=18
18 / 3 = 6
So now we make a fraction 6/72,
3/36
1/12
1 ÷ 12 = .08333333
<em>Thus,</em>
<em>the volume of the new pyramid is 1/8 times the volume.</em>

Answer:
58. 2 real roots; see attached for a graph
59. -6, 3
Step-by-step explanation:
58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.
__
59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.
