Answer:
![y=-\frac{1}{100}(x-50)^2+25](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B100%7D%28x-50%29%5E2%2B25)
the height of the arch 10 feet from the center is 24 feet
Step-by-step explanation:
An arch is in the shape of a parabola. It has a span of 100 feet, the vertex lies at the center 50 and the maximum height of 25 ft.
Vertex at (50,25)
vertex form of the equation is
, (h,k) is the center
![y=a(x-50)^2+25](https://tex.z-dn.net/?f=y%3Da%28x-50%29%5E2%2B25)
the parabola starts at (0,0) that is (x,y)
![0=a(0-50)^2+25](https://tex.z-dn.net/?f=0%3Da%280-50%29%5E2%2B25)
subtract 25 from both sides
![-25=a(-50)^2](https://tex.z-dn.net/?f=-25%3Da%28-50%29%5E2)
![-25=a(2500)](https://tex.z-dn.net/?f=-25%3Da%282500%29)
divide both sides by 2500
![a=-\frac{1}{100}](https://tex.z-dn.net/?f=a%3D-%5Cfrac%7B1%7D%7B100%7D)
![y=-\frac{1}{100}(x-50)^2+25](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B100%7D%28x-50%29%5E2%2B25)
the height of the arch 10 feet from the center.
center is at 50, 10 feet from the center so x=40 and x=60
![y=-\frac{1}{100}(40-50)^2+25](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B100%7D%2840-50%29%5E2%2B25)
y=24
the height of the arch 10 feet from the center is 24 feet
