Convert the equation to the standard form for a hyperbola by completing the square on x and y. x2 - y2 + 6x - 4y + 4 = 0? (x + 3)2 + (y + 2)2 = 1 (x + 3)2 - (y + 2)2 = 1 (y + 3)2- (x + 2)2 = 1 (y+3)^2/16 − (x+2)^2/36 = 1

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.
