Best ResponseYou've already chosen the best response.0(h(t)=16t^2+vt+c where h is the approximate height in ft t is the time in motion in seconds v is the initial upward velocity in ft per second and c is the initial height in ft) A baseball player hits a pitched ball when it is 4ft above the ground the initial upward velocity is 80ft/s how long will it take for the ball to hit the ground???

Best ResponseYou've already chosen the best response.0Consider the given equation h(t)=16t^2+vt+c. We are looking to find t, where v=80ft/s and c=4ft. h(t) represents the height when it hits the ground, that's h(t)=0. So: \[0=16t^2+80t+4 \implies 4t^2+20t+1=0 \] Now solve the quadratic equation for t. Take only the positive value.

Best ResponseYou've already chosen the best response.0You just solve the equation for t. Are you allowed to use a calculator?

anonymous

Best ResponseYou've already chosen the best response.0\[t={b \pm \sqrt{b^24ac} \over 2a}={20\pm \sqrt{20^2+16} \over 8}\]

Best ResponseYou've already chosen the best response.0or you can just write the equation in your calculator and it will give you the answer directly.

Best ResponseYou've already chosen the best response.0a=4, b=20, c=1. Plug them in the equation.

Best ResponseYou've already chosen the best response.0ok u have 2 understand i got like 11 more problems to do and im not understanding where u getting these numbers 4rm when it comes 2 math i gotta be talked 2 like im slow so i can pick it up quick u have 2 explain how u got a b c from dat word problem the only numbers i got from the equation is 16 80 and 4 so please explain

anonymous

Best ResponseYou've already chosen the best response.0okay, then take a=16, b=80 and c=4. That will work exactly the same.

Best ResponseYou've already chosen the best response.0y u make it so difficult u like my teacher just tell me the simple answer lol so do i use dat equation 4 all these problems

anonymous

Best ResponseYou've already chosen the best response.0You told me you got the first equation. This is a quadratic equation, it can always be solved by the quadratic formula, which I wrote above. The question now is what a, b and c.

Best ResponseYou've already chosen the best response.0once i use the formula u gave me is there a step after dat 2 get the 5.1

anonymous

Best ResponseYou've already chosen the best response.0No, you have just to use your calculator correctly. Better to take it step by step, like start with the part under the square root.
