1. Which of these sequences of transformations would not return a figure to its original position?
A. Reflect a figure across line q, and then reflect the image across line q again.
B.
Rotate a figure 270º counterclockwise about point C, and then rotate the
image 90° clockwise about the same point.
C. Translate a figure 4 units up, and then translate the image 4 units down.
D. Translate a figure 2 units to the right, then 5 units to the left, and then 3 units to the right.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
