Answer:
Step-by-step explanation:
Derive the equation of the parabola with a focus at (6, 2) and a directrix of y = 1. A f(x) = −1/2 (x − 6)2 + 3/2. B f(x) = 1/2 (x − 6)2 + 3/2. C f(x) = −1/2 (x + 3/2)2 + 6.
Answer:
24
Step-by-step explanation:
So, first subtract 105-28=77
Now simplify the ratio given. 105:90=21:18=7:6
So she has 77:90 right now. You want it to be 77:66 to fit the ratio.
