I WILL GIVE YOU A MEDAL AND BECOME A FAN IF YOU ANSWER MY QUESTION.

A ball is thrown into the air with an upward velocity of 32 feet per second. Its height, h, in feet after t seconds is given the function h(t)=-16t^2+6. How long does it take the ball to reach its maximum height? What is the ball's maximum height? Round to the nearest tenth, if necessary.

a)reaches a maximum height of 22 feet after 1.00 seconds.
b) reaches a maximum height of 22 feet after 2.00 seconds.
c)reaches a maximum height of 44 feet after 2.17 seconds.
d)reaches a maximum height of 11 feet after 2.17 seconds.

I know you're anxious to finish this homework, or whatever it is, but please understand that you may not just ask for someone else to do your work and to provide you with an answer.  Please see what the OpenStudy Code of Conduct has to say about that.

I have seen this problem (homework problem) before.  I'm assuming that you're in Algebra 1, like the previous student is.

If that's true, then you may have to determine the correct answer by trial and error.

Look at a:  "a)reaches a maximum height of 22 feet after 1.00 seconds."  t=1 sec; h(1)=22 feet.  Substitute those values into the given formula for h.  Is the equation then true or false?

Continue doing this until you find the correct answer.

Okay, thank you.

You'll need to look at all four answer choices.  The chances are great that only one of them is correct.  It's up to you to determine which one is correct, by substituting the t and h values given in each one.

none of those answers are correct.

@richyw:  Please let @nichole_rawr_ do that for herself.  We are not to give out answers; we are here to help the questioner determine his or her own answer.

richyw · Answer

@mathmale. I understand that. but if none of the solutions are correct then how are they supposed to get the answer?

mathmale · Answer

Ask @nicole to do a screen shot of the original problem statement and upload it.  When none of the answers seems to be correct, it's often because the problem was not copied and shared properly.
