A guy wire is a cable used to restrain objects from moving. They are used to support towers or poles.

A guy wire is attached to a cell tower. The 50-foot long guy wire is attached to a tower such that the angle formed by the ground and the wire measures 35°. The guy wire is replaced by a guy wire 120 feet long. The point at which the new guy wire attaches to the tower is the same as it was with the original wire.

What is the approximate measure of the angle formed by this new guy wire and the ground?

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
