PAHELP PO PLEASE...KAHIT NOT SIGURADO SAGOT
Suppose the lowest point of a Ferris wheel is 1.5 meters off the ground, and its radius is 15 m. It makes one complete revolution every 30 seconds. Starting at the lowest point, find a cosine function that gives the height above the ground of a riding child in terms of the time t in seconds.

Answer:
a-value radius 15m(D=30)
b- the period 30s
b=0.2094
c- there is none in the cosine pattern
d-the centre of the wheel is 1.5 m above the ground ,so that will be the midline
the cosine pattern is upside down so you need to put a negative in front
h(t)=-15cos0.2094 t+1.5
