3. Use the quadratic formula to solve the following problem: Mr. V has just autographed a math textbook for the Biebs (aka Justin Bieber). Still in shock over who he has just met, Justin Bieber drops the book. A falcon flying overhead decides he would like to make some money by selling the book on Amazon. If the falcon is 100 feet in the air and dives at a speed of 220 feet per second, how much time does Justin Bieber have to react before the falcon takes the book?

4. I can’t believe that just happened. It was Mr. V! OMG! Autographed Textbook 220 ft/sec Answer: 0.44 sec

8. Use the discriminant to determine how many x-intercepts/solutions/zeros the following quadratic equations have. one solution no solution two solutions

9. Use the discriminant to determine how many x-intercepts/solutions/zeros the following quadratic equations have. Support your answer up by graphing! two solutions

10. Use the discriminant to determine how many x-intercepts/solutions/zeros the following quadratic equations have. Support your answer up by graphing! no solution

11. Use the discriminant to determine how many x-intercepts/solutions/zeros the following quadratic equations have. Support your answer up by graphing! one solution

12. Use the discriminant to match the equations with their potential graphs! A.B. C. ACB

13. Complete the three problems below. Exit slips will be collected and random slips will be drawn. If your paper is drawn and you are correct, you must explain your work for the class. Prize: extra credit on tomorrow’s quiz! Tell if the equation has two solutions, one solution, or no solution. 3) Is it possible for the equation below to have a graph like the one shown. EXPLAIN! 1)2) One solutionNo solution No, because the discriminant of the equation is positive, so the graph should have two x-intercepts.
