Write the formula using the "language" of variation. f = mv2/r, where f is the centripetal force of an object of mass m moving along a circle of radius r at velocity v
What will be an ideal response?
The centripetal force of an object varies directly as its mass and the square of its velocity and inversely as the radius of the circle it moves along.

Solve the problem.Economists use what is called a Leffer curve to predict the government revenue for tax rates from 0% to 100%. Economists agree that the end points of the curve generate 0 revenue, but disagree on the tax rate that produces the maximum revenue. Suppose an economist produces this rational function
