The height of the arch 50ft from the center is 97ft
Step-by-step explanation:
A bridge over a gorge is supported by an arch in the shape of a semi-ellipse
The length of the bridge is 400 ft. and the maximum height is 100 ft
so, a=200ft
b=100ft
(a)
we can draw picture
(b)
now, we can use equation of ellipse formula
now, we can plug
a=200
b=100
we can plug x=50 and find y
