Warm Up 1) Factor: 25x2 – 81 2) Solve by Factoring: 2x2 - 126 = 4x 3) An object is dropped from a height of 1700 ft above the ground. The function gives the object’s height h in feet during free fall at t seconds. When will the object be 1000 ft above the ground?

Homework Answers. Compare your graphs with your neighbor. Ms Homework Answers **Compare your graphs with your neighbor. Ms. Overton will call out necessary information. a. 40 feet b.49 feet c. 3.5 sec a. 7 sec b. 484 feet 4 sec a. y=-16x2 + 1821 b. 57 feet

Recall… Find the quadratic model to the nearest 2 decimal places and then answer the question that follows.

Last one… Find the quadratic model to the nearest 2 decimal places and then answer the question that follows.

Put everything away except for your calculator and a pencil. QUIZ TIME!  Put everything away except for your calculator and a pencil. Remember the HUSKY HONOR CODE that you signed!!

2 3 1 Let’s ignore the questions on your paper and focus on these… Which egg has the highest maximum? How did you figure this out? Which egg goes the farthest distance? How did you figure this out? 3) Based on our answer for number 1, can we write an question for that graph???

Putting them all together… 1) The baseball team has decided to have a throwing contest. Below is the data for 3 different players. Joe Michael Henry y = -16x2 + 50x + 5 Time (x) Height (y) .5 37.5 1 63 2 90 3 85 0 1 2 3 Time (seconds) a) Whose ball was in the air the longest? b) Who threw their ball the highest? c) If you were to determine the winner of the contest, who would you choose and why?

Horizontal Distance (x) 2) Three surveyors are having a discussion about bridges in New York City. The first surveyor collected data from the Verrazano Bridge, he measured the height of the cable as he drove from one end to the other. The second surveyor took a picture of the cable for the Brooklyn Bridge. The last surveyor came up with an equation to model the cable height of the Tappan Zee bridge. Verrazano Bridge Brooklyn Bridge Horizontal Distance (x) Height of Cable (y) 160 100 114.4 200 77.6 300 49.6 400 30.4 500 20 Tappan Zee Bridge y = .00025x2 - .2x + 100

Questions for Bridge Problem 1) Using the information, determine the length of each bridge to decide which one is longest and shortest. 2) Which bridge’s cable gets the closest to the road? How do you know this? 3) Analyze the data to determine which bridge a trucker should use if their truck’s height is 15 ft. How did you come to this conclusion? Which bridge should he avoid and why?
