ferris wheel is drawn on a coordinate plane so that the first car is located at the point (30,0). what are the coordinates of the first car after a rotation of 270° about the origin?

1. option A is correct i.e., .

2. option B is correct.

3. the coordinates of the car after a rotation of is (0,-30).

Step-by-step explanation:

1. The angle of rotation is .

To calculate the angle of rotation we can use a protractor and measure the angle between two corresponding angles, using point C as a center.

2. Given: ΔPRS with coordinates P(-3,2), R(2,5) and S(0,0) is rotated through an angle of 270°, the new image will be as follows;

The formula for rotation through 270° is: (x,y) → (y,-x)

hence our image will be at point:

P(-3,2)→P'(2,3)

R(2,5)→R'(5,-2)

S(0,0)→S'(0,0)

from the above, the approximate image will be option B.

3. Given: Ferris wheel is drawn on a coordinate plane at the point P(30,0). The coordinates of the car after a rotation of is (0,-30).

Because the formula for rotation through 270° is: (x,y) → (y,-x).

So, point P(30,0)→P'(0,-30).

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
