A rider gets on a Ferris wheel at the lowest point of rotation and completes one full revolution in 3 minutes. The Ferris wheel has a diameter of 24 m and a centre that is 13 m above the ground. The height of a rider above the ground, y, in metres, can be modelled by the sinusoidal function y a sin(bt 1.57) + d where t is the elapsed time in minutes. Which of the following functions best models the height of the rider during the rotation of the Ferris wheel? Select one: O a. y = 12 sin(1.05t - 1.57) + 13 O b. y = 12 sin(2.09t - 1.57) + 13 Oc y= 24 sin(1.05t - 1.57) + 13 O d. y = 24 sin(2.09t- 1.57)+ 13

Question
A rider gets on a Ferris wheel at the lowest point of rotation and completes one full revolution in 3 minutes. The Ferris wheel has a diameter
of 24 m and a centre that is 13 m above the ground.
The height of a rider above the ground, y, in metres, can be modelled by the sinusoidal function
y = a sin(bt 1.57) + d
where t is the elapsed time in minutes.
Which of the following functions best models the height of the rider during the rotation of the Ferris wheel?
Select one:
O a. y = 12 sin(1.05t 1.57) + 13
O b. y = 12 sin(2.09t - 1.57)
Oc y= 24 sin(1.05t - 1.57) + 13
O d. y = 24 sin(2.09t 1.57) + 13
