Chapter 11.4, Problem 72E
APPLICATIONS
The Arch of a Bridge The opening of a railway bridge over a roadway is in the shape of a parabola. A surveyor measures the heights of the three points on the bridge, as shown in the figure. He wishes to find an equation of the form
to model the shape of the arch.
(a) Use the surveyed points to set up a system of linear equations for the unknown coefficients
(b) Solve the system using Cramer’s Rule.
