+33616 snoopy1205:A car driving over a suspension bridge is supported by a cable hanging between the ends of the bridge. Since its shape is a parabolic, it can be modeled by a quadratic equation. The height above the road bed of a bridge's cable h in inches measured at distance d in yards from the first tower is given by h=d^2-36d+324.
If the driver of a car looks out at a height of 49 inches above the road bed, at the distance(s) from the tower will the driver's eyes be at the same height as the cable?
