a) what is the diameter

b) where is the rider at x=0? explain the significance

c)how high off the ground is the rider at the top of the wheel?

d) at what times will the rider be at the bottom of the ferris wheel?

e) how long does it take for the ferris wheel to go through one rotation

a) 134 meters

b) i graphed this and found the y value for when x=0 and it was not at the bottom of the graph what does this mean? if time/x is zero shouldn't they rider be at the bottom?

c)137 meters

d)15.7436 (from graphing) is there a way to solve this without graphing?

e)30 min

can you check my answers can help me with b) and d)
