Inquiry
8. A radio transmission tower sways in a strong wind so that the top moves back and forth
as much as 56 cm with a period of 6.0 s. This motion can be modeled using a sine
function. (7 marks)
a) Sketch a graph of the sideways displacement of the tower, d, from its normal position as a
function of time, t, for 12.0 s. 
b) Graph it the function (hint: you need to find amplitude, period, h shift, axis of the curve if
they apply to your graph) 
9. The height of a rider on a Ferris wheel, in metres, can be modelled by the function
h(x) = 9 sin(x − 90)+ 10 ,where x is the rotation angle, in
degrees, that you’re on the ride. (5)
a. What is your maximum height on the Ferris wheel?
b. What is your minimum height on the Ferris wheel?
c. How far off the ground is the centre of the Ferris wheel?
d. What is the radius of the Ferris wheel?
