Hi! I found the vertex for this problem, but how would I find the rest of the equation?
1 answer:
If you're working with focus and directrix, you know the equation of the quadratic is
.. y = 1/(4p)*(x -h)^2 +k
where p is the distance from focus to vertex or half the distance from focus to directrix. P is positive when the focus is above the directrix, as here. Of course, (h, k) is the vertex.
Selection (4) is appropriate.

Step-by-step explanation:
We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.
We begin solving by cross multiplying numerator to denominator of each fraction.
