doesnt the equation stat of with y = 20 sin

anonymous · Answer

start

anonymous · Answer

what do you think the amplitude is?

anonymous · Answer

20? im not sure

anonymous · Answer

thats why i posted the question

anonymous · Answer

ok.. i agree it's 20... so your equation will at least look like this:
$\large f(t)=20sin(Bx+C)+D $
now we gotta find B, C, and D...

anonymous · Answer

can you tell me what the period is?  ie, how long until the ferris wheel makes a complete revolution?

anonymous · Answer

25?

anonymous · Answer

no.. a period is the length of 1 cycle of the graph....
try measuring from highest peak to highest peak....

anonymous · Answer

i dont know what your taking about

anonymous · Answer

sorry i meant to write out the function as:  $\large f(x)=20sin(Bx+C)+D $

anonymous · Answer

if you take a look at the graph, it looks like the distance from peak to peak (or you can also measure from lowest point to lowest point) is 4..  you agree?

why did u close the problem?

i figured it out
