Hi, I am having trouble answering these questions and I was hoping you could help. I am sorry the pictures are upside down. These questions have all the information included there is no missing or incomplete information :)

1. Determine the roots of each quadratic equation using a method of your choice. Show your work. Submit a screen capture of your graph if you use a graphing application, such as a spreadsheet or applet. a. v2 - 2v-24= 0(2) Answer: b. 11-6x = 0.8x2 (2) Answer: 2. Use your preferred strategy to factor the following expressions. 4a2 -4a -80 (3) Answer: b. 3' 4 x2 + 2x - 18 (3) Answer: C. x4 - 7x2+12 (3) Answer:7. A canopy tour company designs zip line rides through forest and jungle environments. One particular zip line takes the passenger through a waterfall, the maximum height of which is 167 ft! The dimensions of both the zip line and the waterfall are shown in the image. Height (ft) 167 ft zip line water fall 130 ft 75 ft 100 ft Horizontal Distance (ft) a. Model this scenario with a system of equations. (4) Answer: b. Solve the system to find the horizontal distance and height at which point the zip line meets the waterfall. Report the answer to the nearest hundredth of a foot. (2)
