Plz (02.03 mc) which sequence of transformations will change figure pqrs to figure p′q′r′s′? (5 points) select one: a. counterclockwise rotation about the origin by 90 degrees followed by reflection about the x-axis b. counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis c. counterclockwise rotation about the origin by 180 degrees followed by reflection about the x-axis d. counterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axis

Would love some on this! include step by step have a good day!

Suppose you are analyzing the relationship between time and distance given in a table, and there are 4 values for each quantity. you divide distance 2 minus distance 1 by time 2 minus time 1.you then divide distance 4 minus distance 3 by time 4 minus time 3 and get a different answer. what can you say about the relationship?
