Water usage at a car wash is modeled by the equation W(x) = 4x3 + 6x2 - 11x + 7, where W is the amount of water in cubic feet and x is the number of hours the
wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The
mount of decrease in water used is modeled by D(x) = x + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours
ite a function, C(x), to model the water used by the car wash on a shorter day.
C(x) = 4x3 + 4x2 - 11x + 8
C(x) = 3x2 + 4x2 - 11x - 8
C(x) = 3x3 + 4x2 - 11x + 8
C(x) = 4x3 + 4x2 - 11x - 8

pls refer ro the top for answer

answer: it is 8

step-by-step explanation:

you know why its 8

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
