480000
Step-by-step explanation:
Answer:
9-63x
Step-by-step explanation:
9(1-7x)
9-63x
Y=1/16x^2
multiplying both sides by 16 we get:
16y=x^2
The general form of a parabola is:
(x-h)^2=4p(y-k)
thus
4p=16
p=4
The parabola opens upwrd:
Focus: (h,k-p)
(0,0-4)
=(0,-4)
Directrix: y=-4
One solution, the answer is x = 0.
