Suppose that an object is thrown upward with an initial velocity of 64 feet per second off the edge of a 960 -foot cliff. The height \(h(t)\) in feet of the object after \(t\) seconds is given by the function $$ h(t)=-16 t^{2}+64 t+960 $$ a. Find the height of the object at \(t=0\) seconds, \(t=3 \mathrm{sec}\) onds, \(t=6\) seconds, and \(t=9\) seconds. b. Explain why the height of the object increases and then decreases as time passes. c. Factor the polynomial \(-16 t^{2}+64 t+960\).
Factor each polynomial completely. See Examples 1 through 12. $$ x^{2}+6 x y+8 y^{2} $$
Factor each polynomial completely. See Examples 1 through 12. $$ 9 x^{2}+30 x+25 $$
Factor each polynomial completely. See Examples 1 through 12. $$ 2 x^{2}+16 x y+32 y^{2} $$
Factor. Assume that variables used as exponents represent positive integers. $$ x^{2 n}-25 $$
