Suppose a circle has a radius of 4.5 inches. If you double the radius of the circle, does the area of the circle double as well? What happens to the circle’s circumference? Explain and justify your reasoning.

Math Notation: x^2 means x raised to the second power or x squared. Explain how to translate the graph of y = -x^2 to produce the graph y = -x^2 + 3. What would the graph look like?

Find the vertex and axis of symmetry of y = -2x^2 + 4x + 1. Show all of your work and justify your reasoning. Note: The ^ symbol means to the power.

The drag force F (in pounds) of water on a swimmer can be modeled by F = 1.35s^2 where s is the swimmer’s speed ( in miles per hour). At what speed is the force minimized? **Note** ^ means "to the power of."

For a person of height h (in inches), a healthy weight W (in pounds) is one that satisfies this system of inequalities: W is greater than or equal to (19h^2)/703 and W is less than or equal to (25h^2)/703 Graph the system for 0 is less than or equal to h...
