Sophia is starting a tutoring service to make some extra money. She plans to charge $8.50 per hour plus a base fee of $12. Write a function that could be used to represent her total charge for tutoring, y, as a function of the number of hours she tutors, x.

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)

An objects motion is described by the equation d= 4sin (pi t) what will the height of the object be at 1.75 seconds?

What percent of the circle below is shaded?
