Suppose a piece of dust finds itself on a cd. if the spin rate of the cd is 470 rpm, and the piece of dust is 4.2 cm from the center, what is the total distance (in m) traveled by the dust in 4 minutes? (ignore accelerations due to getting the cd rotating.) m

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: y=4000x+14000
