A water collection tank has two compartments and the volume is measured in cubic centimeters. The
total volume of water collected in the tank is
modeled by the function V(x) = 16x9 + 12x + 56,
and the volume of water collected in the first
compartment is modeled by the function f(x) =
4.2x – 12.6x2 + 12.6x – 4.2, where x represents
–
the amount in cm the water level rises. If the level
in the second compartment rises by 2.5 cm, what
is the volume in cubic centimeters of water added?
