The length of the rope for this case is given by the length of the circumference.
We have then:
C = 2 * pi * R
Where,
R: Earth radio.
We have then:
C = 2 * pi * (6371)
C = 12742 * pi
Answer:
the length of this rope is:
C = 12742 * pi
• Given the table of values, you can identify these points:

If you plot them on a Coordinate Plane, you get:
As you can observe, it is a Linear Function.
• The equation of a line in Slope-Intercept Form is:

Where "m" is the slope of the line and "b" is the y-intercept.
In this case, you can identify in the graph that:

Therefore, you can substitute that value and the coordinates of one of the points on the line, into this equation:

And then solve for "m", in order to find the slope of the line.
Using this point:

You get:

Therefore, the equation for the data in Slope-Intercept Form is:

Hence, the answer is:
• It represents a Linear Function.
,
• Equation:
Let S = spoon
Let K = knife
1 knife is thee times the cost of a spoon, so it would be 3S
Now you have 9S + 12K = 82.80
We can replace the K with 3S:
9S +12(3S) = 82.80
Simplify the left side:
9S + 36S = 82.80
Add:
45S = 82.80
Divide both sides by 45"
S = 82.80 / 45
S = 1.84
One spoon cost $1.84
We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:
Knife = 1.84 x 3 = $5.52
It would be -(-31) because a negative and negative is a positive
