Consider circle h with a 3 centimeter radius. if the length of minor arc rs is
5/2π, what is the measure of ∠rst? assume that chords rs and ts are congruent.

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.
