A unicycle wheel has a diameter of 20 inches. How many inches will the unicycle travel in 8 revolutions? Use π = 3.14 and round
cluponka [151]

Answer:

502.40 inches

Step-by-step explanation:

First we need to find the circumference of the wheel, which is given by pi times the diameter:

C = (3.14)(20) = 62.8 inches

That's how far the unicycle will travel in 1 revolution, so from there just multiply by 8

D = (62.8)(8) = 502.40 inches

What are the discontinuities of the function f(x) = x^2+2x-8/12x+24?
Advocard [28]
Factor the numerator and denominator of the function to find holes, vertical asymptotes, and horizontal asymptotes.
Numerator: (x - 2)(x + 4)
Denominator: 12(x + 2)
This would mean there is infinite discontinuity at x = -2 (the vertical asymptote).
