+125 Jackson gets on a ferris wheel at its lowest point which is 10 feet above the ground
He notices that he is 50 feet above the ground at his highest point
it takes jackson 40 seconds to make one revolution
-what is the period of the function
-what is the amplitude of the function
-what is the midline of the function?
-lastly what is the equation that models the sinusoidal function?
+129852 The period = 40 seconds
The ampllitude is (50 - 10 ) / 2 = 40/2 = 20
The midline = (50 + 10) / 2 = (60/2) = 30
We have the following form
y = A sin (B t) + C
A = the amplitude = 20
B = 2pi / period = [ 2pi / 40 ] = pi/20
C = the midline value = 30
So....the function is
y = 20sin [ pi * t / 20 ] + 30
