The height over time of a person riding a Ferris wheel can be modelled using a sinusoidal function for a person riding a Ferris wheel with the following characteristics: 0 The person reaches a maximum of 15 m. I The person reaches a minimum of 'I m. 0 It takes 70 s for the Ferris wheel to turn once. 0 At time 0, the person is at height 1 m. Determine the equation of the sine-function that can be used to model these data. Express in the format f(x) = a sin(b(x-c)) + d [2 marks] Graph the function and attach a copy of your graph to this question [1 mark] Describe how you determined the value of the a,b,c and d variables in the function.
