Question
The figure shows a telephone wire hanging between two poles at x = -35 and x = 35. The wire hangs in the shape of a catenary described by the equation given. y = c + a cosh() -35 35 x If the length of the wire between the two poles is 71 ft and the lowest point of the wire must be 20 ft above the ground, how high up (in ft) on each pole should the wire be attached? (Round your answer to two decimal places.)
