An object moves along the -axis. the graph shows its position as a function of time . find the average velocity of the object from points b to c

Average velocity = distance / time

=(0-25) / (6-3)

= -8.3 answer

 The correct option is (A) -8.3 m/s.

Step-by-step explanation:  Given that an object moves along the -axis and the graph shows its position as a function of time.

We are to find the average velocity of the object from points B to C.

From the graph, we see that

the co-ordinates of the point B are (3, 25) and that of C are (6, 0).

That, is (x, t) = (3, 25)  and  (6, 0).

Therefore, the average velocity of the object from points B to C is given by

Thus, the required average velocity of the object from points B to C is -8.3 m/s.

Option (A) is CORRECT.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
