a ball is dropped from a balcony. the height, h meters, of the balcony above the ground t seconds after it is released is modeled by the quadratic function h(t)=78.4-4.9t^2. how far is the ball above the ground after 4s?

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.
