The average amateur golfer can hit a ball with an initial upward velocity of 28.3 meters per second. The height can be modeled by the equation h=-4.9t^2+28.3t, where h is the height of the ball, in meters, after t seconds. At what heights is the ball hit?

When is the ball at its maximum height

what is the maximum height if the ball

how long did it take to hit the ground

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
