Quick QUESTION!
A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:
f(n) = 9(0.7)^n
What does the number 0.3 represent?

Best ResponseYou've already chosen the best response.0@jim_thompson5910 This is a quick question. Is the answer A?

Best ResponseYou've already chosen the best response.1I don't see 0.3 in f(n) = 9(0.7)^n

Best ResponseYou've already chosen the best response.0Yeah me neither. But could it be A though? Since this is decreasing, it would be by 30%

Best ResponseYou've already chosen the best response.1when n = 0, what is f(n)

Best ResponseYou've already chosen the best response.1and when n = 1, f(n) = ??

Best ResponseYou've already chosen the best response.1so what change happened from 9 to 6.3

Best ResponseYou've already chosen the best response.1you took 70% of 9, yes

Best ResponseYou've already chosen the best response.1that means each next height is 70% of the previous height

Best ResponseYou've already chosen the best response.1which is why I'm thinking they meant to say 0.7 instead of 0.3

Best ResponseYou've already chosen the best response.0Oh ok! Thank you! It was probably a typo

Best ResponseYou've already chosen the best response.1yeah if it said "the ball loses 30% of its height each bounce", then it would work

Best ResponseYou've already chosen the best response.1since 100%  30% = 70%
