Answer:
As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.
The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.
Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).

Answer:
The point that the graph does not pass through is (3,1)
Step-by-step explanation:
we have
(0, 5), (2, 2), (3, 1), and (4, -1)
Draw the points, and join them to plot the linear equation and determine which point does not belong to the line.
using a graphing tool
see the attached figure
therefore
The point that the graph does not pass through is (3,1)
x = A cos ω t
where,
A is the amplitude
ω is the angular frequency
Since the shape is a circle, therefore the amplitude is
simply equal to 2π or 6.28 rad while the angular frequency is 5 rad/s, therefore:
x = 2π cos 5 t
