The answer above is NOT correct. (4 points) A cable hangs between two poles of equal height and 26 feet apart. Set up a coordinate system where the poles are placed at x - -13 and r = 13, where r is measured in feet. The height (in feet) of the cable at position r is h(r) =18 cosh(x/18), where cosh(x) = (er + e ) /2 is the hyperbolic cosine, which is an important function in physics and engineering The cable is 28.88 feet long
