PLEASE ANSWER THE FOLLOWING!

The height of the pole of the wind turbine at Exhibition Place in Toronto is 94 m. It has 3 blades each measuring 24 m in length. The blades turn at a frequency of 20 revolutions per minute (hint: how long for one revolution?).

1)Determine a sinusoidal (sine or cosine) function which will model the height of one of the blades which starts at the lowest point above the ground. (Please state the period, equation of axis, the max value, the min value, the phase shift and the amplitude)

2)Graph your equation using desmos and input it here. Limit your graph to 4 cycles. I.e restrict domain and make sure your screenshot is clear and easy to see

3)Determine the domain and range of the function (of the 4 cycles)

4)Using your graph, determine all times in the first cycle when the tip of one blade is 100 m above the ground.
