4.  Solve

1430 = 0.55t^2 + 550

1430 - 550 =880 = 0.55t^2

880/0.55 = 1600 = t^2

t= \pm \sqrt{1600} = \pm 40

On the positive answer makes sense.

Answer: Month 40

5. The throw ends when the height is zero (I guess we're ignoring rolling).

0 = -0.02x^2 + x + 6

x = \dfrac{-1 \pm \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)}

Only the negative sign for the plus/minus will give a sensible, positive answer:

x = \dfrac{-1 - \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)} = 55.4138

Answer: 55.4 feet
