The figure below shows a rope that circles the Earth. The radius of the Earth is 637163716371 kilometers.
Assuming the rope makes a perfect circle, what is the length of this rope?

the real question is why is this guys last name heavyfoot

step-by-step explanation:

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
