Would the zeroes have meaning in the problem situation? Use a complete sentencein your answer.Sample Answer: No, the solutionnegative time. 1 8doesn’t make sense, because you can’t have20. What is the height of the balloon 0.5 second after launch? Show all your work and use acomplete sentence in your answer.y = –16(0.5) 2 + 20(0.5) + 2.75y = –4 + 10 + 2.75y = 8.75The height of the balloon 0.5 second after launch is 8.75 feet.21. What is the discriminant? How does it help you determine the number of solutions to aquadratic equation? Use complete sentences in your answer.© 2008 Carnegie Learning, Inc.The discriminant is the expression b 2 – 4ac. If it is positive, then there are two solutions.If it is zero, then there is one solution. If it is negative, then there are no solutions.242 Chapter 3 ■ Assessments Georgia Mathematics 1
