A carousel rotates at the rate of 0.15 rev/s with an 80-kg man standing at a point 2.0 m from the axis of rotation.

(a) What is the new angular speed when the man walks to a point 0.7 m from the center? Assume that the carousel is a solid 25-kg cylinder of radius 2.0 m. Answer is in rad/s

(b) Calculate the change in kinetic energy due to this movement. Answer is in Joules

hi
i gotta draw a graph by a given equation so i fint the roots for the x values and i can do that with equations like y=(x-3)(x+5) cos then my values are just x=3 and x = -5 but then i cam across 2 questions i couldnt do
one is y= 12/x
and the other is
y= 3^x

please could someone explain how to put this into a graph
thnx xxx

Hey Thanks alot to the people who answered my last question it was a big help! I also was wondering about another thing with inequalities. The directions say, "Solve the inequality. Write a sentence that describes the solution" The questions says 6+2x>20 or 8+x<0. I don't have it answered but if someone could explain to me how to do this it would be a big help! Thanks!!
