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?

how much boiling water (L) must you add to a luke warm tub (25 degrees Celsius, 1000L) to bring the temperature up to 40 degrees Celsius. I believe that the equation goes something like this: Mass1*Specific Heat Capacity of water*initial temperature= (Mass1+Mass2)(Specific Heat Capacity of water)(Final temperature)
