The standard equation of parabola:
(y-k)²=4p(x-h), with:
a) vertex = (h,k)
b) focus = (h+p, k)
c) directrix = (x=h-p)
Since this parabola has a vertex at (0,0) that means h=k=0
Hence the equation becomes: y²=4px, let's calculate p:
focus is given (-9,0) Remember h+p = -9 & since h=0, then p= -9
===> y²= - 36x
Answer:
Add 3 to X to get Y
Step-by-step explanation:
1 + 3 = 4
2 + 3 = 5
Answer:
$7.81
Step-by-step explanation:
89¢ + 95¢ + $1.79 + $1.29 + $2.89
So numerically to add it the equation is...
0.89 + 0.95 + 1.79 + 2.89 + 1.29 = $7.81
