Answer:
Archimedes was the first to derive this formula.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The answer to an absolute value must be positive
here are examples of simple ones
ex1:|-5|=5
ex2:|-3|=3
<span>ex3:</span>|3|=3
Step 
<u>Find the slope of the given line</u>
Let

slope mAB is equal to

Step 
<u>Find the slope of the line that is perpendicular to the given line</u>
Let
CD ------> the line that is perpendicular to the given line
we know that
If two lines are perpendicular, then the product of their slopes is equal to 
so

Step 
<u>Find the equation of the line with mCD and the point (3,0)</u>
we know that
the equation of the line in the form point-slope is equal to

Multiply by
both sides


therefore
the answer is
the equation of the line that is perpendicular to the given line is the equation
