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

f(n) = 16(0.5)ⁿ⁻¹

Step-by-step explanation:

Find f(1) for each option.

a) f(1) = 16(0.5)¹⁻¹ = 16

b) f(1) = 32(0.5)¹⁻¹ = 32

c) f(1) = 16(0.5)¹ = 8

d) f(1) = 32(0.5)¹⁺¹ = 8

Only the first option matches the table.

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
