find the height of the arch at distances of 10, 30 and 50 feet from the center.
Substitute the x values in the equation to find the y values

10 feet from the center would be x=50 and x=70; this will check our equation
they should be equal
x | y
-------
50|24.3
70|24.3

30 feet from the center: x=30, x=90
30|18.75
90|18.75

50 ft from center: x=10, x=110
10|7.64
110|7.64
