Question

PLEASE HELP… PLEASE ANSWER CORRECTLY

The problem states that the initial coordinates of Henry’s family is at the coordinates (-4, 4). Each 15 minutes the restaurant will rotate 90° every 15 minutes. If we follow the Cartesian plane and the center of the restaurant being at (0, 0) we know that the table will be situated at the (4, 4) coordinates of the restaurant after the first rotation. After the 30 minute mark, the restaurant rotates one more time and moves the table of Henry’s family at the (4, -4) coordinates of the restaurant as the center of the restaurant will never move.

    Answer:

    30 minutes later, they would be located at (4,- 4)

    To see this……note that they would have rotated (2 x 90) degrees = 180 degrees in 30 minutes

    And (-4, 4) is located on the line  y = -x

    And since a line is a straight angle measuring 180 degrees, then (4, -4) is also on this line, rotated 180 degrees from (-4, 4)
