If a stone is tossed from the top of a 270 meter building, the height of the stone as a function of time is given by h(t) = -9.8t2 – 10t + 270, where t is in seconds, and height is in meters. After how many seconds will the stone hit the ground? Round to the nearest hundredth’s place; include units in your answer.
2.
Rewrite with positive exponents. Assume that even roots are of nonnegative quantities and that all denominators are nonzero.

Given the quadratic function f(x) = 25x2 – 100x + 100, find a value of x such that f(x) = 25.
4.
Use polynomial long division to divide
3x3 + 8x2 – 13x – 4
by
x2 + 4x + 1
