Chan wants to make sure his girlfriend catches the T-shirt, so they need to figure out which bleacher row she should sit in. Chan launches from center court. The Tshirt’s travel path, according to the manufacturer’s manual, is represented by the equation y = −0.05x2 + 2.5x, where y represents the vertical height in feet in terms of the horizontal distance traveled, x, in feet.  \nThe bleachers begin 32 feet from center court and each bleacher row has a height of 1.5 feet and a width of 2 feet as shown in the diagram. Use a line to represent the bleachers which touches the front edge of each row of seat and touches the floor 30 feet from center court as shown in the diagram. The diagram is not necessarily drawn to scale.  \nFlying T-Shirts  \n2 ft  \n1.5 ft  \n Center Court  \n30  \nBleachers  \n1. If the center court is represented by the origin on a coordinate plane, what is the equation for the line that touches the front edge of each of the bleachers?  \n2. What row should Chan tell his girlfriend to sit in to get the T-shirt? Explain how you determined your answer.  \n3. An equivalent form ofthe T-shirt’s travel path y = −0 .05x2 + 2 .5x is y = −0 .05(x − 25)2 + 31 .25 . What form of the equation is the new form? Confirm they are equivalent.  \n4. What do you notice about the coefficient in the equation y = −0 .05(x − 25)2 + 31 .25 and key points about the T-shirts path?  \n5. How do you think the equation y = −0 .05(x − 25)2 + 31 .25 would change if the T-shirt reached a maximum height of 40 feet? Justify your reasoning.  \n\n| Flying T-Shirts Rubric |  |  |\n| --- | --- | --- |\n| The core elements of performance required by this task are:\u003Cbr>• Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically.\u003Cbr>Based on these, credit for specific aspects of performance should be assigned as follows. | points | section\u003Cbr>points |\n| 1.
