Hints: - What is the value of h (0]? I Is this the maximum value of h (t), the minimum value of h [t], or a value between the two? - The function Sin (t) has a value between its maximum and minimum at t = 0 , so can h (t) be a straight sine function? - The function cos (t) has its maximum at t = D, so can h (t) be a straight cosine function? c. If the Ferris wheel continues to turn, how high off the ground is a person aer 20 minutes? 21 6-1 Discussion: Trigonometric Models Back to Topic 6-1 Discussion: Trigonometric Models Mike Booth posted Apr 6, 2023 11:07 AM to Group 1 % Subscribed A Ferris wheel is 20 meters in diameter and completes 1 full rotation in 8 minutes. revolves ..> diameter 1 meter ground A. Amplitude : A = 10 We were given the diameter of the ferris wheel which was 20. So to figure out the radius would be ? Which would be 10. Midline :H = 11 We are able to find this by taking the radius and adding 1 for the disnce from the ground to the loading | Period: P = 8 How long it woudl take to make a full roation around. B. Y = ACos(Bx - C) + D Using the information already provided, I constructed this equation. Y = -10COs(it) + 11 C. Given that one Rotation is 8 minutes. and the person was on the ride for 20 We can simply divide 20 by 8 which would give us 2.5 or 2 and 1 half rotaions. This would mean that the person would be at the furthest point at 20 meters plus 1 foot for the distance = 21 & pico.jpg (51.73 KB) Reply to Thread
