aksik [14]

50 L X 3 = 150 L (water value for horses)
4 L X 15 = 60 L (water value for sheep)
200 mL X 12 = 2,400 mL or 2.4 L (water value for chickens)
Add them all together.
150 + 60 + 2.4 = 212.4 L of water is used daily

Answer:

P(x) = -1/2(x -3)²(x +3)

Step-by-step explanation:

When q is a root of the polynomial, (x-q) is a factor. This polynomial will be ...

P(x) = a(x -3)²(x +3)

For x=0, the y-intercept will be ...

P(0) = 27a = -13.5

Then the value of a is ...

a = -13.5/27 = -1/2

The formula for P(x) is ...

P(x) = -1/2(x -3)²(x +3) . . . . . . factored form

P(x) = -0.5x³ +1.5x² +4.5x -13.5 . . . . standard form
