Step-by-step explanation:
p(y)=2+y+2y²-y³
p(0)=2+(0)+2(0)²-(0)³=2+0+0-0=2
p(1)=2+(1)+2(1)²-1³=2+1+2-1=4
p(2)=2+2+2(2)²-2³=4+8-8=4

<span>Let x=amount of time it takes both pipes draining together to empty the pool
First pipe empties at the rate of 540,000/150=3600 liters/min
Second pipe empties at the rate of 540,000/225=2400 liters/min
Together, both pipes empties at the rate of 3600+2400=6000 liters/min, so our equation to solve is:
6000*x=540000 </span>
