Find the displacement

55.

Step-by-step-explanation:

In a velocity/time graph like this the total displacement is the area of the body.

This is the area of (from left to right) of triangle OBF + area of the 2 rectangles + area of triangle CDE

Here this is 1/2 * 2 * 5 + 5 *4 + 5 * 4 + 1/2 * 5 * 4

= 5 + 20 +  20 + 10

= 55.

55

Step-by-step explanation:

The displacement is the area under the line

The are comprises of

So the area is:

the answer will be b x² +x-1

step-by-step explanation:

"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.
