The Ferris Wheel first appeared at the 1893 Chicago Exposition. Its axle was 45 feet long. Spokes radiated from it that supported 36 wooden cars, which could hold 60 people each. The diameter of the wheel itself was 250 feet. Suppose the axle was located at the origin. Given that the starting point is at the loading platform, find the location of the car at the 270 counterclockwise rotation position.a.(0, -125)c.(0, 125)b.(125, 0)d.(-125, 0)

Graph Quadrilateral ABCD whose vertex matrix is shown below. Then graph the dilation of Quadrilateral ABCD with a scale factor of 3 on the same coordinate grid.Quadrilateral ABCD with vertex matrix a.c.b. d.

Use matrices to determine the coordinates of the vertices of the reflected figure. Then graph the pre-image and the image on the same coordinate grid. with vertices reflected over the x-axis.a.c.b.d.

The wind was blowing quite strongly when Jenny was baby-sitting. She was outside with the children, and they were throwing their large plastic ball up into the air. The wind blew the ball so that it landed approximately 3 feet east and 4 feet north of where it was thrown into the air.If represents the original location of the ball, write a matrix that represents the location of the translated ball.a.c.b.d.

The coordinates of the vertices for square CDEF translated 3 units right and 4 units up if the vertices are C(-3, 1), D(1, 5), E(5, 1), and F(1, -3) areC’(0, 5), D’(4, 6), E’(8, 6), and F’(4, -1)
