A shower has a flow rate of 2.3 gallons per minute. If a person takes an average of 6 showers per week and the average length of a shower is 15 minutes, then how much water is used in a year? 10764 is the answer but part 2 says If the same person replaces the shower head with a low-flow shower head that has a flow rate of 1.5 gallons per minute, how much water will be saved in a year? Assume the length and frequency of showers does not change
answer is in gallons/yr​

the correct answer is d

hope this

step-by-step explanation:

the shape,the size and the distance

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
