Red aerial mini-flares are used by some boaters in an emergency. The flight of one brand of flare, when fired at an angle of 70° to the horizontal is modelled by the function h = -9t^2 + 72t + 2, where h is the height, in metres and t is the time, in seconds, since the flare was fired. Write an equation in the standard form. What is the maximum height of the flare?
