Answer:
- C. V = 15 x 4.2
- D. V = 7.5 x 2 x 4.2
Step-by-step explanation:
The volume is the product of the three dimensions, so can be figured as ...
7.5 × 2 × 4.2 . . . . choice D
Carrying out the first multiplication, this will be equivalent to ...
15 × 4.2 . . . . . . . . choice C

You can't do that. There is no answer
Hi, thank you for posting your question here at Brainly.
The general equation of a horizontal ellipse is
(x-h)2/a2 + (y-k)2/b2 = 1, at center (h,k) while a = semi-major axis, b = semi-minor axis. These are related through the distance of the focus from the center,c. a2 = b2 + c2.
If you draw the points on a coordinate plane, the center of the ellipse is at (0,0), so h and k equals 0. Then, the minor axis (2b) spans from 8 to -8 of the y-axis. This is equal to 16 units. Hence,
2b = 16
b = 8
b^2 = 64
The distance between the two foci is 2c. Thus,
2c = 12
c = 6
c^2 = 36
Then, a2 = 64 + 36 = 100. Substituting to the general equation:
x^2/100 + y^2/64 = 1
