40 or 45 degrees I say dis cuz if u find da overall area then u can find the degrees
each term is negative and 1/4 of previous term so the nth term is the n-1 term times -1/4 so f(n)= -1/4 f(n-1)
The answer is 4/5
its very simple
1 at runner can run 6mph you n 3 minutes
2nd runner can 6mph in 2*3=6
1st runner can run 9 mph in 9*3=27
2nd runner can run 9mph in 9*6=54
