Simplify the radical expressions in Exercises \(67-74\) if possible. $$\sqrt[3]{150}$$
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. In one short sentence, five words or less, explain what $$\frac{\frac{1}{x}+\frac{1}{x^{2}}+\frac{1}{x^{3}}}{\frac{1}{x^{4}}+\frac{1}{x^{5}}+\frac{1}{x^{6}}}$$ does to each number \(x\).
Factor each perfect square trinomial. $$4 x^{2}+4 x+1$$
A football was kicked vertically upward from a height of 4 feet with an initial speed of 60 feet per second. The formula $$h=4+60 t-16 t^{2}$$ describes the ball's height above the ground, \(h,\) in feet, \(t\) seconds after it was kicked. Use this formula to solve Exercises \(19-20 .\) What was the ball鈥檚 height 2 seconds after it was kicked?
What is a perfect square trinomial and how is it factored?
