Gven that there are 12 quarts of wastewater in one barrel, and given that the recycling facility picks up 120 full barrels on each trip, this means that the recycling facility picks up 12 x 120 = 1,440 quarts of wastewater.
Given that wastewater is <span>filling barrels at the rate of 11 quarts per hour, then the number of hours taken to fill 1,440 quarts of wastewater is given by

hours.
To find the number of days between each pick-up, recall that there are 24 hours in one day, therefore, the number of days between each pick-up is given by

Therefore, there are 6 days between each pick-up

Answer:
a) a^6+6a^4b+15a^2b^2+20b^3+15(b^4/a^2)+6(b^5/a^4)+(b/a)^6
b) 20
c) a^6+6a^4+15a^2+20+15/a^2+6/a^4+1/a^6
Step-by-step explanation:
(a+b/a)^6=a^6+6a^5(b/a)+15a^4(b/a)^2+20a^3(b/a)^3+15a^2(b/a)^4+6a(b/a)^5+(b/a)^6
a^6+6a^4b+15a^2b^2+20b^3+15(b^4/a^2)+6(b^5/a^4)+(b/a)^6
b) the coefficient of b^3=20
c) if b=1, the expression is
a^6+6a^4+15a^2+20+15/a^2+6/a^4+1/a^6
The vertical line test is used to see if a drawn line on a graph is truly a function or not. A function is defined as for every input (x value) there is ONE output (y value). So if you're able to draw any vertical line through a point and get one y value for every x value, then the graph drawn is a true function. If you drawn a vertical line and you get two y values for one x value, then the graph is not a true function
