Step-by-step explanation:
Y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2
Answer:
4 in
Step-by-step explanation:
The volume for a triangular pyramid is:
1/3AH = V
Let's first find the area of the base:
Area = 1/2bh = 1/2(12)(8)=48
Now we plug the area of the base and the volume back into the formula:
V = 1/3AH
64 = 1/3(48)(H)
64 = 16H
H = 4 in
