Aball is thrown from an initial height of 7 feet with an initial upward velocity of 33 ft/s. the ball’s height h (in feet) after t seconds is given by the following. h=7+33t-16t^2. find all values of t for which the ball’s height is 23 feet.

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.
