Answer:
x<−3+√1012 or x>−3−√1012
Step-by-step explanation:
4d = 1/3
d = 1/3/4
d = 1/12
Thus, c is the correct choice.
Answer:
4/9
Step-by-step explanation:
using cross canceling you see
(4(5)(6)(7)(8))/(5(6)(7)(8)(9))
everything cancels except for the 4 on top and the 9 on the bottom so
4/9
Answer:
Step-by-step explanation:
The vertex is halfway between focus and directrix, at (0,0).
The equation has the form y = ax².
Focal length p = distance between focus and vertex = 1
p = 1/|4a|
1 = 1/|4a|
|a| = ¼
The focus lies below the vertex, so the parabola opens downwards and a<0.
y = -¼x²
