If the grist mill completes the rotation in 8 seconds. Then the final position of the bucket after 6 seconds is (0, 9).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

A water grist mill has a radius of 9ft and takes 8 seconds to make a complete rotation. a bucket starts at position (9,0).

Then the coordinates of the bucket's location after 6 seconds will be

The angle of rotation after 6 seconds will be

\rightarrow \dfrac{6}{8} \times 360\\\\\rightarrow 270^o

Then we have

x = 9 cos 270°

x = 0

and y will be

y = 9 sin 270°

y = -9

But the angle is in a clockwise direction, then

y = 9

More about the coordinate geometry link is given below.

Answer:

(0, −9.0)

Step-by-step explanation:

6 seconds is 68 of a complete rotation.

Calculate the angle of rotation.

68(360∘)=270∘

The rule for this particular rotation is: (x,y)→(y,−x).

This rotation changes all x distances into y distances, and all y distances into x distances of the opposite sign.

The figure shows three points on a Cartesian plane. Point A is at nine, zero. Point B lies on the negative direction of y axis. Point O is at the origin. Angle A O B measures 270 degrees. Segment O B has a length of 9 units. The angle is highlighted in red.

Apply this rule to the point (9,0).

(9,0)→(0,−9).

Therefore, the coordinates of the bucket's location after 6 seconds are (0,−9.0).
