The diameter d in inches of a rope required to lift a weight of w tons is given by the function d = 10w π . how much weight can a rope that measures a radius of 2 inches lift (truncate the decimal to the hundredths)?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
