Janessa hits a golf ball. the height of the golf ball can be modeled by the function h(t)=-4.9t^2+12t, where t is given in seconds approximately how many seconds is the ball in the air? 1points hint: the question is asking how long the ball is in the air. this time ends when the ball hits the ground. so, set the equation equal to zero to represent the height when the ball hits the ground. set the given equation equal to 0. factor out a gcf. (t) divide each term by t to find the remaining polynomial inside the parentheses. set each polynomial equal to zero. solve to find time, t. which answer makes sense? a 0 seconds b ‒2.45 seconds c 4.9 seconds d 2.45 seconds
