9 would be a coefficient since it is a number in-front of a variable
Where p is the distance the focus is above the vertex, the equation of a parabola with vertex (h, k) can be written as
... y = 1/(4p)·(x -h)² +k
The vertex is halfway between the focus and directrix. The focus of your parabola is on the y-axis at y=6, and the directrix of your parabola is at y=-6, so the vertex of your parabola is on the y-axis at y=0. That is, the vertex is
... (h, k) = (0, 0).
The distance p from the focus at y=6 to the vertex at y=0 is 6 units, so
... p = 6.
Filling these values into the equation gives
... y = 1/(4·6)·(x -0)² +0
... y = (1/24)x²
The answer is common ratio
Answer:
the answer is: 22
Step-by-step explanation:
F + 2b = 92
3b + 4f = 212
———————————
You didn’t say you need them solved, but just in case:
f = 92 -2b
3b + 4(92-2b) = 212
3b + 368 -8b = 212
-5b = -156
b = 31.20
f + 2(31.20) = 92
f + 62.4 = 92
f = 29.60
3(31.2) + 4(29.6) = 93.6 + 118.4 = 212
