Determine which of these relations are transitive. The variables x, y, x', y represent integers A.x~y if and only if x +y is pos
itive. B. (x, y)~(x/.y/) if and only if x+yx+y C.x~y if and only if xy 2 0 D.x~y if and only if x + y is even. Ex~y if and only if xy is negative. Fx~y if and only if x-y is a multiple of 10.
Average acceleration: ( v - v o ) / Δ t v = 0 m/s, v o = 20 m/s, Δ t = 3.5 s a (average) = ( 0 m/s - 20 m/s )/3.5 s = - 20 m/s / 3.5 s = = - 5.7142857 m/s² ≈ - 5.71 m/s²
