On Geogebra make a circle of any radius and change its color to red so it will stand you as your circle of inversion. Make a triangle that is completely outside of your circle of inversion that does not touch the circle of inversion and then find the inversion of the triangle over the red circle. You can use the Geogebra tools for any of the constructions we already know how to do (such as perpendicular lines or midpoints) instead...

Multiple choice questions: Circle the correct answer 9) Suppose Host A sends four TCP segments back to back to Host B over a TCP connection. The sequence numbers in the four segments are 70, 90, 110, and 130, respectively. Suppose that the second segment is lost but all the other segments arrive at B. In the acknowledgement that Host B sends to Host A after the fourth segment arrives at B, the acknowledgement number is (a) 70; (b) 90; (c)...

Suppose four teams, numbered one through four, play a single-elimination tournament, consisting of three games. Two teams play each game and one of them wins; ties do not occur. The tournament bracket is as follows: teams one and another team play each other in the first game and the remaining two teams play each other in the second game; the winner of the first game plays the winner of the second game in the third game. Define a set ΩΩ...
