Ok so has 524.96
must be at least 500
took out 32.50 out of 524.96
how much does she need to put in to get to 500 so
524.96-32.5=492.46
how much till 500
500-492.46=7.54
needs to deposit at least 7.54
inequality is
<u />524.96-32.50+x<u>></u>500
x=how much she needs to deposit
All 4 are right triangle congruence theorems.
Answer:

Step-by-step explanation:
The distance between the focus and the directrix is the vertical distance from the point to the line:
1 -(-3) = 4
The vertex is half that distance between the point and the line, so is at x=2 and ...
y = (-3 +1)/2 = -1
The vertical scale factor of the quadratic is 1/(4p) where p is the distance from vertex to focus. Here, that distance is 2, so the equation in vertex form is ...
y = (1/(4·2))(x -2)² -1
y = (1/8)(x -2)² -1
_____
<em>Check</em>
Any point on the parabola is equidistant from the focus and directrix. This is easily checked at the vertex, which is halfway between focus and directrix, and at the points having the same y-value as the focus. Those two points are (-2, 1) and (6, 1), both of which are 4 units from the focus and 4 units from the directrix.
Set up a proportion
42.50/5=x/8
5x=340
x=68
He would earn $68
On't want to be ripped off do you?/ That's why you want to have some interest. Just in a simple form this is a rush job right now.
