EXAMS NEXT WEEK! Help with Review! Giving Points!
The height of a javelin in feet is modeled by h(t)=16t^2+79t+5, where t is the time in seconds after the javelin is thrown. Determine the maximum height of the javelin. After how many seconds does the javelin reach its maximum height? How many seconds does it take for the javelin to hit the ground?
1. Determine the maximum height of the javelin.
2. After how many seconds does the javelin reach its maximum height?
3. How many seconds does it take for the javelin to hit the ground?

Best ResponseYou've already chosen the best response.0ok to find the x value in which you have your maximum y value use the equation b/2a in which we pull the terms from the form of ax^2+bx+c

Best ResponseYou've already chosen the best response.0considering your x value is actually time i think at your maximum height would be the x value in which you found your maximum height. I seriously doubt they want us to use kinematics equations.
