Solve each system by the method of your choice. $$\left\\{\begin{array}{l} x^{2}+4 y^{2}=20 \\ x+2 y=6 \end{array}\right.$$
Solve and graph the solution set on a number line: $$\frac{x-2}{x-1} \geq 1$$ (Section \(2.7,\) Example 4 )
Determine whether each statement makes sense or does not make sense, and explain your reasoning. You told me that you flew against the wind from Miami to Seattle in 7 hours and, at the same time, your friend flew with the wind from Seattle to Miami in only 5.6 hours. You have not given me enough information to determine the average velocity of the wind.
Verify your solutions to any five exercises from Exercises \(1-42\) by using a graphing utility to graph the two equations in the system in the same viewing rectangle. Then use the intersection feature to verify the solutions.
An object moves in simple harmonic motion described by \(d=6 \cos \frac{3 \pi}{2} t,\) where \(t\) is measured in seconds and \(d\) in inches. Find: a. the maximum displacement b. the frequency c. the time required for one cycle.
