General equation of parabola: y-k = a(x-h)^2
Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2
All we have to do now is to find the value of the coefficient a.
(1,2) is on the curve. Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.
The equation of this parabola is y = 2x^2.
The answer will be 9 1/12 because if you add them up you get 11/12. So the mixed number would be 9 1/12
All you have to do is solve for x. See the following steps below.
Step 1. Subtract

from both sides

Step 2. Simplify

to

Answer:
C
Step-by-step explanation:
It is C because the 2 is attached to the variable Y
A = pi r^2
A = 5^2 pi
A = 25 Pi
so semi-circle = 25 pi / 2
answer is a) 25 pi / 2 m^2
