Answer: 0.512
Step-by-step explanation:
256/32=8
8*(0.4)^3=
8*0.064=0.512
y=0.512
The correct answer is b), or x² = -12y.
Explanation:
This equation may be written in standard form as

The coefficient in front of x² is negative so the curve is downward.
The vertex has coordinates (0,0).
The vertex is equidistant from the directrix and the focus, so the focus is (0, -3).
