Here you go, sometimes, quizlet is there with just the right info. Ur welcome.
Ok first I call the slope gradient
The gradient is
rise / run
This means
The change in the y value over two points/
The change in the x value over two points
eg
(3,5) (6,7)
Let’s say I took those two points out of my graph
Then the gradient is
7-5 / 6-3
Rise/run
Which is
2/3
Now let’s the the same with yours
Choose two points on your graph and do the same

Answer: 1/4 or 0.25
Step-by-step explanation:
If the take the origin as the starting point of the ball, then the vertex would be (4,28) and the parabola would be facing downwards. Using the general form of the parabola which is (x-h)^2 = 4p(y-k) where h and k are taken from the coordinate of the vertex (h,k).
So, the equation would be, (x-4)^2)=4p(y-28). To determine 4p, we can substitute either of the two points: (0,0) or (0,8). The second coordinate is taken from the given that the ball covers a distance of 4 ft after it reaches a maximum height. The total distance traveled by the ball is twice that, which is 8 ft.
After substituting, 4p = -4/7. Plugging this into the equation and after expanding and simplifying, the equation of the ball's trajectory is:
y = (-4/7)x^2+14x
