11. A crocodile open his jaws at a 30 degree angle. He closes his jaws, then opens them again
at a 36 degree angle. In which case is the distance between the tip of his upper jaw and the
tip of his lower jaw greater? Explain.

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
