Question 1009156: The Shape of the galaxy arch in st.Louis Missouri resembles a parabola with the equation h=-0.00635x^2+4.0005x-0.07875 where h is the height in feet and x is the distance from one base in feet
What is the distance from one base of the arch to the other?

The distance between the bases is the distance between the roots of the parabolic equation...
Solving
h=-0.00635x^2+4.0005x-0.07875 = 0 gives us
x = 630 and x = .02
the distance is about 630 feet...
