Midge added some chlorine to the water in a pool. The chlorine evaporated at a fixed rate every week. The table below shows the amount of chlorine f(n), in ounces, that was left in the pool after n weeks:

n f(n)
1 16
2 8
3 4
4 2


Which function best shows the relationship between n and f(n)?

f(n) = 16(0.5)n−1
f(n) = 32(0.5)n−1
f(n) = 16(0.5)n
f(n) = 32(0.5)n+1

Answer 28

Rate at which the total trash increases every day

Answer 29

f(n) = 16(0.5)n

Answer 30

what grade ru in

Answer 31
