7/30/2020 Apex Learning - Project 37. The cross-section of the dome is a semicircle whose radius is 30 feet. Make a sketch showing the cross-section of the dome. (4 points) 30 ft 38. You want to sketch the cross-section of the dome on a coordinate grid. You're going to locate its center at (0, 0). Write an equation for a circle whose diameter is 60 feet and center is (0, 0). (4 points) 39. Rewrite your equation from question 38 to isolate j. (In other words, solve for )2.) Then solve for y by taking the principal square root of both sides. (4 points: 2 points for isolating ) and 2 points for the final equation) 40. Use the equation from question 39 to complete the table of values. When necessary, round y-values to the nearest tenth. Then graph the result to show a cross-section of the ticket office. (8 points: 4 points for the table and 4 points for the graph) https://course.apexlearning.com/public/cpop/4/9/2/3037156 16/187/30/2020 Apex Learning - Project 40 - 35- 30- 25 - X y 20 - 15 - -30 10 - -25 20 - 10 10 20 40 -20 -15 -10 -5 0 5 10 15 20 25 30 In the center of the dome, there will be a large cylindrical ticket kiosk that is 24 feet tall. The top of the kiosk just touches the dome. Assume that the entrance to the dome is at (30, 0). https://course.apexlearning.com/public/cpop/4/9/2/3037156 17/187/30/2020 Apex Learning - Project (0, 0) (30, 0) 41. Use your graph to find how far the edge of the kiosk is from the entrance, to the nearest foot. Explain how you found your answer. (Hint: Find the x-value of the point where y = 24 that is closest to the entrance.) (8 points) 42. When you take the square root of both sides of an equation, you use the symbol + to show that a square root can be positive or negative. Why were you able to leave out the negative possibility when solving for y in question 39? (2 points) pyright @ 2018 Apex Learning Inc.
