Answer: f(8) = 6.25(1.1)^7 ; f(8) = 12.179
Step-by-step explanation: (I got it right on the test)
(1, 6.25), (2, 6.875), (3, 7.5625), (4, 8.31875)
r= 1.1
f(1) = 6.25 / starting number
1. Since it is multiplying each number by 1.1 it is using the Geometric Explicit Formula:
f(n)= f(1) x r ^n-1
f(8) = 6.25 x 1.1 ^(8-1)
f(8) = 6.25 x 1.1 ^7
f(8) = 6.25 x 1.9487171
f(8) = 12.179
The distance is 14 miles; the first jogger finishes in two hours, while the slower jogger is still 12 miles in. The slower jogger then reaches the end of 14 miles twenty minutes later, because 6mph also means 2 miles per twenty minutes.
