Solve the problem.A certain suspension cable with supports on the same level is closely approximated as being parabolic in shape. If the supports are 190 ft apart and the sag at the center is 30 ft, what is the equation of the line along which the tension acts (tangentially) at the right support? (Choose the origin of the coordinate system at the lowest point of the cable.)
