How wide is the archway at ground level?
Answer to Problem 69E
Explanation of Solution
Given information:
A parabolic archway (see figure) is
Calculation:
ConsiderA parabolic archway is
The midpoint of archway as the origin has vertex point
Now to find width of archway at ground level finds parabola equation,
The standard equation of parabola with downward open have vertex at the point
Put the coordinates of vertex
Now substitute
Therefore the equation of parabola is,
Now the point
Hence, the width of archway at ground level
