Use stokes' theorem to evaluate s curl f · ds. f(x, y, z) = zeyi + x cos(y)j + xz sin(y)k, s is the hemisphere x2 + y2 + z2 = 4, y ≥ 0, oriented in the direction of the positive y-axis.

Which rational number could be graphed between -4 and -5

The function f(x)= -(x+5)(x+1) is down. what is the range of the function?
