Transformations 1) Triangle ABC has vertices A(6,2), B(3,4), and C (2,8). If the triangle is rotated 90 counterclockwise, what are the coordinates of the image A'B'C'? 2) Which transformation(s) preserve congruence? 3) Which transformation(s) produce similar gures that are not congruent? Quadratics 4) Solve the following quadratics: a. 2x2 - 3x - 5 = 0 b. 4x2 + 8x + 7 =4 c. 3x2 = 75 d. x2 -11x + 19 = -5 5) The length of a rectangular flower garden is 5 feet more than its width. If the area of the garden is 104 square feet, find the dimensions of the flower garden. 6) The height, h, in feet of an object above the ground is given by h=-16t2+64t+190, where t is the time in seconds and t 2 O. a) Find the time it takes the object to hit the ground. b) Find the maximum height of the object and the time that it will be at a maximum. 7) Write x2+8x=3 in vertex form.Direct & Inverse Variation 8) The time needed to paint a fence varies directly with the length of the fence. If it takes 5 hours to paint 200 feet of fence, how long will it take to paint 500 feet of fence? 9) The time to prepare a field for planting is inversely proportional to the number of people who are working. A large field can be prepared by 5 workers in 24 days. In order to finish the field sooner, the farmer plans to hire additional workers. How many workers are needed to finish the field in 15 days
