12 x 100 - 12 x 5
distributive property
Answer:
<u>Work Done = 27.66 Joules</u>
Step-by-step explanation:
The work done is:

Where
F is the fore
d is the distance moved
is the angle
The force is "4"
The distance is the distance from (1,7) to (8,10)
The distance is the square root of change in y coordinates, squared and sum of change in x coordinates, squared. Hence, distance is:

The angle is gotten by the formula:

So, now:

Work Done = 
<u>Work Done = 27.66 Joules</u>
First, you divide the fraction, and then you multiply it by 100.
So you get:



So, 5/16 is 31.25%
