A ball is thrown upward with an initial speed of 14.7 m/s. The height, h, in meters that the ball reaches t seconds after being thrown is given by the equation h = 14.7t - 4.9t2. When will the ball be 9.8 meters high (Two answers)
A ball is thrown upward with an initial speed of 14.7 m/s. The height, h, in meters that the ball reaches t seconds after being thrown is given by the equation h = 14.7t - 4.9t2. For how long will the ball be in the air? (How long until h = 0)
If a = 0 or b = 0, then ab = 0
If ab = 1, then a = 1 or b = 1.
ab = 0 if and only if a = 0 or b = 0
If x(x - 3) = 0, then x = 0 or 3
