Answer:
Step-by-step explanation:
Step 1
Find the slope of the line EF
we have
The slope of the line EF is equal to
Step 2
Find the slope of the line perpendicular to the line EF
we know that
If two lines are perpendicular, then the product of its slopes is equal to minus one
so
-----> slope of the line EF
Find the value of m2
substitute
therefore
the equation could be an equation for a line that is perpendicular to line EF
12/w or 12 divided by w
I can do this give me a min
50j
workdone = force x distance
workdone = 20x2.5
n=-6
2(n+5)=-2
distribute
2(n+5)
2xn 2x5
2n+10
2n+10=-2
subtract 10 from both sides
10-10=0
-2-10=-12
2n=-12
divide each side by 2
2n/2=n
-12/2=-6
