Aswimming pool is initially shocked with chlorine to bring the chlorine concentration to 6 ppm (parts per million). chlorine dissipates in reaction to bacteria and sun at a rate of about 15% per day. above a chlorine concentration of 2 ppm, swimmers experience burning eyes, and below a concentration of 1 ppm, bacteria and algea start to proliferate in the pool environment.

a. construct an exponential decay function that describes the chlorine concentration (in parts per million) over time.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

the correct answers i think are b. and d.

give me brainliest if it is correct!
