1 Quadrilateral W'X'YZ'is a reflection of quadrilateral WXYZ across the x-axis. Quadrilateral W"X"Y"Z"is a 180° rotation of quadrilateral WXYZ counterclockwise about the origin. We Y 21 -8 -6 -2 -2 Y" 8- X" X' Which of the following statements is true? A Orientation of the vertices is preserved for quadrilateral W'X'YZ'; therefore, only reflections across the x-axis preserve orientation of the vertices. B Orientation of the vertices is preserved for quadrilateral WX"Y"Z"; therefore, only 180° rotations counterclockwise about the 6. 8. 4.

Can someone please help me with these?

(part 1 of 4) Suppose you start at the origin in 3-space, move along the x-axis a distance of 2 units in the positive direction, and then move down- ward a distance of 3 units. What are the coordinates of your position? 1. (2,0, -3) 2. (2, -3,0) 3. (2,0,3) 4. (0, 2, -3) 5. (0, -3,2) (part 2 of 4) Which one of the points P(6, 9, -3), Q(8, -2, -8), R(-5, 8, 1) in 3-space is closest to the xz-plane? 1. R(-5, 8, 1) 2. P(6, 9, -3) 3. Q(8, -2, -8) (part 3 of 4) A rectangular box is constructed in 3-space with one corner at the origin and other ver- tices at (1,0,0), (0,3,0), (0,0,2). Find the length of the diagonal of the box. 1. length 14 2. length 3. length 4. length 5. length 6. length = = = = √22 √14 √19 19 22 (part 4 of 4) What are the coordinates of the projection of the point Q(-4, 5, 3) onto the zx-plane? 1.
