Question 1141419
i believe your answer will be 37.3 meters.


this is a geometric series type question.


the formula is Sn = a * (1 - r ^ n) / (1 - r)


a is the starting number which is 15.


with 10 bounces, the formula becomes S10 = 15 * (1 - .6 ^ 10) / (1 - .6)


solve for S10 to get S10 = 37.27325184.


that rounded to 37.3.


i believe that's going to be your selection.
