The library is at point (1,1). the gym is at point (1,-4). the chemistry lab is at point (-3,6). the restrooms are at point (-3,1). the teacher's lounge is at point (4,6). the principal's office is at point (-5,-4). the auditorium is at point (4,-2). and the physics lab is at point (-1,-2). which of these pairs of places lie 4 units from one another?

Library and restrooms are only the places which lie 4 units from each another.

Step-by-step explanation:

Given that the library is at point (1,1). The gym is at point (1,-4). The chemistry lab is at point (-3,6). The restrooms are at point (-3,1). The teacher's lounge is at point (4,6). The principal's office is at point (-5,-4). The auditorium is at point (4,-2). And the physics lab is at point (-1,-2).

These points are labelled on the graph as shown in attachment.

Now, the points which are nearer we can calculate the distance by distance formula which is written as

Now, distance between the points (-3, 1) and (1,1)

⇒ s=4 units

Now, the distance between the points (-1,-2) and (-5, -4)

⇒ s=

Now, the distance between the points (4,-2) and (1, -4)

⇒  s=

Now, the distance between the points (-3,1) and (-1,-2)

⇒  s=

Similarly, by calculating only 1 pair lie 4 unit from one place to another.

Library and restrooms are only the places which lie 4 units from each another.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
