Solving Quadratic Equations Graphically Given the function f(x) = x²-10x+14 find x when f(x)=-2 using your graphing calculator. Then follow the steps below to show the solutions graph on the computer. [Hint: Use the following window on your graphing calculator: Xmin = -5, Xmax = 13, Ymin=-16, Ymax = 5] 1. Write the solutions as a list of ordered pairs below. Round the values of z to two decimal places. [Hint: If two solutions exist, enter them as (21, Y1), (2, 2). If only one solution exists, enter (21,391). If no solutions exist, enter DNE] 2. Use the Line Tool to draw the Horizontal Line y = -2. 3. Use the Polynomial Tool to draw f(x) = x²-10x+14. [Hint: You will need to find the vertex and one other point] 4. Use the Point Tool to identify the solutions. Write the Points of Intersections as a list of Ordered Pairs Draw the resulting graph and plot the points of intersection

Example A flywheel used for storing energy consists of a uniform disk of mass 1.5 \times 10^5 kg and radius 2.2 m that rotates at 3000 rev/min about its center of mass. Find its kinetic energy. 1. The kinetic energy of rotation is: $K_{rot} = \frac{1}{2}I\omega^2$ 2. Calculate the moment of inertia of the disk: $I = \frac{1}{2}mR^2 = \frac{1}{2}(1.5 \times 10^5 kg)(2.2 m)^2$ $\qquad = 3.63 \times 10^5 kg \cdot m^2$ 3. Convert $\omega$ to rad/s: $\omega = \frac{3000 \text{ rev}}{60 \text{ s}} \times \frac{2\pi \text{ rad}}{1 \text{ rev}} = 314 \text{ rad/s}$ 4. Substitute these values to find the kinetic energy: $K_{rot} = \frac{1}{2}I\omega^2 = \frac{1}{2}(3.63 \times 10^5 kg \cdot m^2)(314 \text{ rad/s})^2$ $\qquad = 1.79 \times 10^10 J$
