The area A of a sector of a circle is given by A= πr^2 S/ 360, where r is the radius of the circle and S is the angle measure (in degrees) of the sector. Solve the equation for S to find the angle measure given the radius and area of the circle. A) S = Aπr^2 / 360B) S = πr^2 / 360AC) S = 360A / πr^2D) S = 360πr^2 / A

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.
