Suppose w is a function of x and y, and that x and y are both functions of t. Suppose further that • the derivative of w versus x at t = 1 is 2; • the derivative of w versus y at t = 1 is 3; • the derivative of x versus t at t= 1 is 5; • the derivative of x versus t at t = 2 is 7; • the derivative of y versus t at t = 1 is 11; and • the derivative of y versus t at t = 3 is 13; where "derivative" means "partial derivative" wherever appropriate. What is the derivative of w versus t at t = 1? O o 05 O 43 O 53 O 184 330 There is not enough information,
