Chang added some chlorine to the water in a pool. The chlorine evaporate in 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 10 weeks n |f(n)
1 | 24
2 | 12
3 | 6
4 | 3

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

^ = To the power of

•f(n)=48(0.5)^n-1
•f(n)=24(0.5)^n
•f(n)=24(0.5)^n-1
•f(n)=48(0.5)^n+1

This is high school algebra by the way

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
