Question 1086406: an arch in the form of an inverted parabola and has a span of 12 feet at the base and a height of 12 feet. determine the vertical clearance of the parabola 4 feet from the vertical centerline Answer by ikleyn(52803) (Show Source):
The equation of this parabola is
p(x) =
(6 units to the left from the vertical centerline to one root and 6 units to the right to the other root;
and the vertex is at 12 ft up).
Now, the question asks about p(4), and you can easy calculate it:
p(4) = = = = ft.
Answer. Verical clearance of the parabola 4 feet from the vertical centerline is ft.
