<h3>Answer:
</h3>
========================================================
Explanation:
The instructions don't mention it, but I'm assuming that the height of 4 feet is the max height the of the ball.
If so, then this is the vertex of the parabola.
The ball is on the ground when x = 0 and x = 10. The x coordinate of the vertex is the midpoint of those two roots. So it's at x = 5.
Overall, the vertex is (h,k) = (5,4)
The equation
y = a(x-h)^2 + k
becomes
y = a(x-5)^2 + 4
Next, we plug in the root (x,y) = (10,0) since the ball hits the ground when x = 10. Let's solve for 'a'
y = a(x-5)^2 + 4
0 = a(10-5)^2 + 4
0 = 25a + 4
25a = -4
a = -4/25
We could have used (x,y) = (0,0) and we'd end up with the same 'a' value.
Therefore, the height function is
Answer:
A:28/500
Step-by-step explanation:
Answer: e = (p-q)/3
Step-by-step explanation:
p = q + 3e
Subtract q from both sides.
p - q = q + 3e - q
p - q = 3e
Divide both side by 3 which is the coefficient of e.
3e/3 = (p - q)/3
e = (p-q)/3
Answer:
Here's wh as t I found
(X-1)²+(y+4)²=4
Step-by-step explanation:
(x-h)²+(y-k)²=r² with the center being at the point (h,k)
and radius being r.
(x-1)²+(y-(-4))²=2²
(x-1)²+(y+4)²=4
