@tomo you don't need logs. cheetos. say that function = the max height and solve for how many bounces. use this http://simple.wikipedia.org/wiki/Logarithm

Answer 9

good observation @RONNCC. I was trying to take a derivative of the function.

Answer 10

\[0.5=3(0.7)^{n}\]

Answer 11

then do we divide by 3? Im confused how we solve for n

Answer 12

take the natural log of both sides.

.5 = 3*(.7)^n

.5/3 = .7^n

ln(.5/3) = ln(.7^n)

// property of logarithms is that you can pull an exponent out of the logarithm
ln(.5/3) = n*ln(.7)

(ln(.5/3))//ln(7) = n

there you have n

Answer 13

what is IN also the final answer is 1.03 but i still do not understand how to get it,we divide by 3 we get \[0.16=0.7^n \]

Answer 14

what is a logarithim

Answer 15

please help i am confused how to find n

Answer 16

ln is the natural logarithm. If you have not covered logarithms yet, you might want to check out that khan academy webpage I referenced above. He explains these concepts very well. I was able to use some of the properties of logarithms to reach the end result. He explains how to use those properties.
