Is anyone able to help with this? Let {I, r, r2, r3, m1, m2, m3, m4} be the symmetries of a square, where: I is the trivial symmetry, r is a clockwise rotation by 1/4-turn, and mi is the reflection in the line mi
Let x and y be variables that represent symmetries of the square.
State True or False, if false give an examples that demonstrates that it is false.

x ◦ y = y ◦ x for all x and y:

(x ◦ y)^2 = x^2 ◦ y^2 for all x and y:

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a mean of $235 and a standard deviation of $20. according to the standard deviation rule, how much did almost all (99.7%) of the students spend on textbooks in a semester?

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2
