Simplify each expression. Assume all variables represent positive numbers. $$ \frac{3}{\sqrt[3]{9}} $$
All of the equations we have solved so far have had rational-number coefficients. However, the quadratic formula can be used to solve quadratic equations with irrational or even imaginary coefficients. Solve each equation. $$ \sqrt{2} x^{2}+x-\sqrt{2}=0 $$
Use a graphing calculator to solve each equation. If an answer is not exact, round to the nearest hundredth. See Using Your Calculator: Solving Quadratic Equations Graphically. $$ 2 x^{2}-5 x-3=0 $$
Water Usage. The height (in feet) of the water level in a reservoir over a 1 -year period is modeled by the function \(H(t)=3.3(t-9)^{2}+14\) where \(t=1\) represents January, \(t=2\) represents February, and so on. How low did the water level get that year, and when did it reach the low mark?
a. \(x^{2}-42 x+441=0\) b. \(x^{2}+42 x+441=0\)
