The volume v of a right circular cylinder of radius r and heigh h is v = pi r^2 h 1. how is dv/dt related to dr/dt if h is constant and r varies with time? 2. how is dv/dt related to dh/dt if r is constant and h varies with time? 3. how is dv/dt related to dh/dt and dr/dt if both h and r vary with time?

What is the quotient of -3/8and-1/3?

Malia is observing the velocity of a cyclist at different times. after two hours, the velocity of the cyclist is 15 km/h. after five hours, the velocity of the cyclist is 12 km/h. part a: write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. show your work and define the variables used. (5 points) part b: how can you graph the equations obtained in part a for the first 12 hours? (5 points) if you can try and make this as little confusing as you can

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?
