Suppose you want to approximate Z b a Z d c f(x, y)dydx by rectangles sampled from either upper-left, upper-right, lower-left, or lower-right corners. If you are told that fx(x, y) < 0 at all points (x, y), what does that tell you about which approximations are larger than which

Someone answer asap for ! michele pushes a box d meters across a floor. she uses a force f, in newtons, to push the box. she pushes the box for t seconds. the formula p = fd/t calculates the power, p, in watts, that it takes for michele to complete the task. solve the formula for d.
