Answer:
405 cubic meters (I think...)
Step-by-step explanation:
9 x 9 = 81
81 x 5 = 405
D. 405
First, you find the area of the swimming pool without the water. That is 9 x 9 = 81. Then you multiply the area (without water) by 5 to find the area with the water.
Vertex: (-1/2, -25/4)
Focus: (-1/2, -6)
Axis of Symmetry: x=-1/2
Directrix: y=-13/2
x = -2, -1, -1/2, 1, 2
y = -4, -6, -25/4, -4, 0
