a flare is fired from the deck of a sinking ship. Its trajectory can be modelled by the function h(t) = -4.9t^2 + 92t where h is the height of the flare in meters and t is the time in seconds. A seagull is flying 100m above the sinking ship. How long will the flare be above the bird if it continues to fly at the same height?

A skydiver jumps out of a plane. The height of a skydiver can be modelled by the quadratic function () = -4.912 + + + 4900, where t is the time in seconds and h, is the height above the ground in metres. After he releases his parachute, his height above the ground can be modelled by the function h (1) -- 51+ 4100. How long after jumping did he release his parachute? (3 marks)

The height, h, in metres, above the ground of a rider on a Ferris wheel can be modelled by the equation: h= 10 sin ((pi/15 t) - 7.5) + 12 where t is the time, in seconds
The height, h, in metres, above the ground of a rider on a Ferris wheel can be modelled by the equation:h= 10 sin ((pi/15 t) - 7.5) + 12 where t is the time, in seconds.At t=0, the rider is at the lowest point. Determine the first two times that the rider is 20 m above the ground, to the nearest hundredth of a second.
