Answer:
D. y = (x - 3)²
Step-by-step explanation:
The parabola formula in vertex form is:
y = a(x - h)² + k
where the vertex is located at (h, k). Replacing with vertex (3, 0) we get:
y = a(x - 3)² + 0
y = a(x - 3)²
In all possible options the leading coefficient <em>a</em> is equal to one. Therefore:
y = (x - 3)²
(180-x) + 18 + 30 + x/2 = 180
=> 180 + 48 - x + x/2 = 180
=> -x/2 + 48 = 0
=> x/2 = 48
=> x = 48×2 = 96°
They got paid the same amount. If you divide 417.96 and 27, you get 15.48. And if you divide 495.36 and 32 you get 15.48.
I hope that helped you.
