A water tank has the shape of a right circular cone with a height of 10 feet and a radius of 4 feet.
a) Write the height 'h' of the water in the tank as a function of the radius 'ľ of the water. [i.e., find h (r)
b) Suppose water is pouring into the tank so that the radius 'r' of the water is given by r= t, where 't'
is in minutes. If the volume 'V' of the water in the tank is given by V = r r² h, find a simplified
%3D
formula for V (t) .
12. a). Use polynomial long division to divide P (x) = 2x³ + 3x – 2x³ – 7x + 4
by (–x² +1). Write your answer using either of the two forms shown in class.
b) Is (x + 1) a factor of P (æ) ? Show/explain your reasoning.
