Solve the equation using factoring or the quadratic formula, whichever is appropriate. make sure to simplify your answers.

0.01y2−0.02y−0.04=0

Step-by-step explanation:

Eliminate the fractions first.  Multiply all terms by 100, obtaining:

y^2 - 2y  + 4 = 0.  The quadratic equation is the faster method here.  The discriminant, b^2 - 4ac, is 4 -4(1)(4), or 4(-15).  Because this result is negative, the equation has two complex roots:

      -(-2) ± √(4)(-15)

x =

                 2

or

      2 ± 2i√15

x =

             2

d.) yes, because the volume of the cone is greater than the volume of the sphere
