Answer:
y = -2(x - 4)^2 + 4.
Step-by-step explanation:
Vertex form:
y = a(x - 4)^2 + 4 (because the vertex is at (4, 4)).
To find the value of a we substitute the point (2, -4):
-4 = a(2-4)^2 + 4
4a = -8
a = -2.
Move the a five across and bup 2 and across 3
0.47619047619 and just round so it'll be 0.48
Answer:
y = -0.005x² + 50
Step-by-step explanation:
The diameter is 200 feet, so the parabola has roots at (-100, 0) and (100, 0). The maximum height is 50, so the vertex of the parabola is at (0, 50).
Using vertex form of a parabola:
y = a (x − h)² + k
y = a (x − 0)² + 50
y = ax² + 50
Plugging in either root:
0 = a (100)² + 50
a = -0.005
y = -0.005x² + 50
