Let f be a function of two variables that has continuous partial derivatives and consider the points
A(1, 1),
B(7, 1),
C(1, 13),
D(9, 16).
The directional derivative of f at A in the direction of the vector
AB is 9 and the directional derivative at A in the direction of
AC is 2. Find the directional derivative of f at A in the direction of the vector
AD. (Round your answer to two decimal places.)
