21 points. ! a hot tub has 58 inches of water (w) when it's full. the tub drains at a rate of 7 inches per minute (m): w = 58 - 7m after you open the drain, how many minutes will it take for the hot tub to have 23 inches of water remaining? ? answer in # of minutes

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.
