Answer: total length 5780
Step-by-step explanation:
1st wire. 340m
2nd wire. 1360m
3rd wire. 4080
56=2(pi)(r)
r=8.9127
pi(8.9127)^2=249.56cm^2
≈245cm^2 (3s.f.)
Since the line is parallel, the same coefficients can be used for x and y. The constant on the right needs to change so that the given point will satisfy the equation.
... 5x - 4y = 5(-8) -4(2) = -40 -8 = -48
Your equation is
... 5x -4y = -48
Let's try this.
First, we have the absolute value of -4(-2)-8, or the absolute value of 8-8, so 0.
Let's forget about that, now. It's 0, it adds no value. Let's not worry about it.
For the next, we see the absolute value of -1-(-2)^2
Or:
-1-4, or -5.
Next is 2(-2)^2, or 2(4) = 8.
Therefore, we have -5+8 =3.
If you see any errors, let me know.
Otherwise, I hope this helps!
