Identify the image of ∆XYZ for a composition of a 300° rotation and a 60° rotation, both about point Y. HEl 10 mins left

A positive 90° rotation around the y -axis (left) after one around the z -axis (middle) gives a 120° rotation around the main diagonal (right). In the top left corner are the rotation matrices, in the bottom right corner are the corresponding permutations of the cube with the origin in its center.

Step-by-step explanation:

x>9

Interval!

(9,infinty)

Step-by-step explanation:

2x>18

divide by 2

x>9

This means that the interval is

(9,infinty) because after 9 x exists, whereas from (-infinity, 9) x does not exist
