(-2,8), (4,0)In the diagram, OM is the radius of the larger circle and also the diameter of the smaller circle. Chord EM of the larger circle cuts the smaller circle at N. If EM = (2x² - 2) units and ON = 2x units, express, giving reasons, the length of the radius of the larger circle in terms of x.
- Find the perimeter of the rectangle with vertices R (−4, 1), E (−1, 4), C (5, −2), and Y (2, −5). Round the answer to the nearest hundredth (2 decimal places).(8.4, q.18) PLEASE SHOW WORK STEP BY STEP AND CIRCLE ANSWERYvonne wants to use a dissection argument to justify the formula for the area of a circle. She dissects the circle into congruent sectors and reassembles the sectors as a parallelogram–like figure. The diagram below shows the arrangement for a circle dissected into 8 sectors. Yvonne knows that as the number of sectors of the circle increases, the reassembled figure becomes closer and closer to an actual parallelogram so that it can be used to determine the area of the circle. Determine the value of each characteristic of the parallelogram in the table below. Select the best value for each characteristic

She walks a distance of 10.35 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. She then walks 2 more meters past the mirror, so that when she turns around and looks down at the mirror, she can see the top of the flagpole clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.45 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.Find the coordinates of the point on the unit circle measured 3.5 units counterclockwisealong the circumference of the circle from (1, 0). Round your answer to four decimalplaces.
