Question 1 The radius of the Ferris Wheel is 34 feet, the center height is 43
feet, and it takes 20 seconds to make a complete circle.
y=__+__ sin(__t)

but which class are u may know that first

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
