Answer:
$72500
Step-by-step explanation:
$72500
Since the focus is at (0, 2) and directrix is y = -2
point where both of these have the same x-value will be at (0, 2) for the focus and (0, -2) for the directrix.
The vertex will also have the same x-value so it will be (0, y).
y-value is half-way between the y-value of the focus, and the y-value of the directrix at x = 0.
Directrix y-value is -2 at x = 0 and for the focus it's 2 at x = 0.
Halfway between y = -2 and y = 2 is y = 0.
So the vertex of the parabola occurs at (0, 0).
So that's x^2 = 4ay = 4(2)y = 8y.
y = 1/8*x^2

Answer:
The graph is shown in the picture attached.
Step-by-step explanation:
<u>Defining:</u>
- x represents the number of minutes
- y represents the number of points scored
<u>Matt scored:</u>
- 12 points (y) in 20 minutes (x) is shown in the graph as the point (20, 12)
- 16 points (y) in 28 minutes (x) is shown in the graph as the point (28, 16)
- 15 points (y) in 24 minutes (x) is shown in the graph as the point (24, 15)
- 18 points (y) in 25 minutes (x) is shown in the graph as the point (25, 18)
10+48 = 58 / 2 = 29.

Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
