\[f(x) =125 \left( \frac{2}{5}\right)^x \] or am I too blue-eyed about this problem ?

lol...everybody got it except me..:D
ghazi
  • ghazi
every time it bounces 2/5 of it's original height..but first bounce is counted when it went 125 inches
anonymous
  • anonymous
125 *(2/5)^4
ghazi
  • ghazi
and after that you need to count for four more

@saifoo.khan Do u have the answer key
saifoo.khan
  • saifoo.khan
why are we inserting 4? Why not 3?
saifoo.khan
  • saifoo.khan
@Yahoo! , nope.
saifoo.khan
  • saifoo.khan
Because the first bounce has already happened. We are left with 3 of them now?
anonymous
  • anonymous
hmm, you have a point there @saifoo.khan
saifoo.khan
  • saifoo.khan
So @mukushla we correct? :D
ghazi
  • ghazi
because question asked for four bounces after the ball dropped
saifoo.khan
  • saifoo.khan
"After the first bounce " it reaches the height of 125 @ghazi
anonymous
  • anonymous
Yup.....@mukushla was correct
anonymous
  • anonymous
Yes I guess my interpretation of that text is flawed it is x=3, which are four bounces, for x=0 initial bounce at a height of 125
saifoo.khan
  • saifoo.khan
Yep!

So medals for Muk?
ghazi
  • ghazi
agreed...!!

Funny formula in general, according to it the ball can do more than one hundred bounces :D Clearly a real world phenomenon!

  • saifoo.khan
Hehe. Thanks all.
ghazi
  • ghazi
not only hundred ...it can go infinite theoretically
