The height in feet, h, of a base jumper Is jumping off a cliff is given by the equation h = 3t^2 - 700t + 2000,
where t is the time is seconds. How long will it take the jumper to reach the ground?

233 seconds

Step-by-step explanation:

When h = 0 the jumper ends his/her jump. Therefore let h = 0 so that we can solve for t; forming a quadratic equation

0 = 3t^2 - 700t + 200

I am going to solve  using the quadratic formula, but there are other approaches--

Now the solutions are around 233 and 0.3 seconds. Given these two solutions I would find the first one more predictable.

6mm^3 or .6cm^3

factor trees are nice.
