Natalya Lisovskaya set the women's shot put world record of 22.63 meters. Her throw can be modeled by h = -4.9t2 + 13.7t + 1.6, where t is time in seconds and h is the height in meters. About how long was the shot in the air?I need this by tomorrow please if you could do the steps too so i can understand?!

Answer :

h = -4.9 t^2 + 13.7t + 1.6

h = 22. 63 meters

h = -4.9 t^2 + 13.7t + 1.6

22.63 = - 4.9 t^2 + 13.7t + 1.6

Solving by quadratic equation,

The equation above gives a solution with an imaginary number, please recheck the equation for h and use the quadratic equation to solve for the time , t .
