1)
The distance between points A and B is;

,
and if you wanted to you could measure out the legs of that hypotenuse using the slope between A and B, but I'm going to show you the easier way;
Δx = 4
Δy = -20
So from the midpoint, add 4 to the x-value and subract 20 from the y-value.
{(5+4),(-8-20)}
(9,-28) is the endpoint.
2)
Do the same thing as I did above;

So

is the distance.
Sorry for the delay, life delayed me a ton ,:D
Answer:
41.6666667
Step-by-step explanation:
Velocity = distance/time
Velocity = 625/15
Velocity = 41.6666667
Answer:
Volume of Cylinder =

So :
Step-by-step explanation:

A square has all the sides being equal.
Since the top can fit 3 color tiles, then the side must fit the same number of tiles.
Therefore, 3 roles and 3 columns of tiles will be required.
The number of tiles required will calculated similar to area of a square. That is,
Number of tiles = 3*3 = 9 tiles.
