A homeowners' association monitored the number of households in a neighborhood using their sprinkler systems during certain hours. The graph below shows the information recorded for two days. The function describing this graph is a transformation of the parent cosine function, y = cos x.
Which value best describes the period of the transformed function? A. 24 hours B. 12 hours C. 18 hours D. 16 hours

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

b). 4320 have a nice day

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
