The equation k = mv2 represents the energy an object has based on its motion. the kinetic energy, k, is based on the mass of the object, m, and the velocity of the object, v. lashandra is given k and v for 10 different objects. in order to make solving more efficient, she solves the equation for m : m = . after attempting to determine the mass of a few objects, lashandra realizes there must be something wrong with her formula. what is lashandra’s error?

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.
