  A ball is thrown from an initial height of
  
  meter with an initial upward velocity of
  . The ball's height
  (in meters) after
  seconds is given by the following
  
  h=1 plus  25 t subtract 5t exponent 2
  
  Find all values of
  for which the ball's height is
  meters.

  yes it helped very much could you also help me with this ?
  
  A model rocket is launched with an initial upward velocity of
  
  202/fts
  
  . The rocket's height
  
  h
  
  (in feet) after
  
  t
  
  seconds is given by the following.
  
  h=202t-16t2
  
  Find all values of
  
  t
  
  for which the rocket's height is
  
  82
  
  feet.

  Put 82 in for h
  
  82 = 202t - 16 t^2
  
  subtract 82 and put it in the right form:
  
  16t^2 - 202t + 82 = 0
  
  To make the math easier, we can divide everything by 2
  
  8t^2 - 101t + 41 = 0;  that gives us a=8, b=(-101), and c = 41 for the quadratic formula.

  that confuses me a bit
  
  Apr 30th, 2015
  
  Okay,
  
  Which part was confusing?
  
  Apr 30th, 2015
  
  How do you get the decimal
  
  Apr 30th, 2015
  
  Plug the numbers (a, b, and c) into the quadratic formula and solve.

  okay so i got 12.205 and 0.4199 could you help me round it to the nearest hundreths and check if its right first please
  
  Apr 30th, 2015
  
  you there ?
  
  Apr 30th, 2015
  
  Yes, I'm here.  Let me check...
  
  Apr 30th, 2015
  
  I got 13.02 and -0.39  (however, the negative value will not work in this case.)
  
  Apr 30th, 2015
  
  could you help me set it up to get the right number for the square root cause i got -751 with positive 38 but with -38 i got 769 i confuse my signs when im supposed solve the 4*ac part
  
  A ball is thrown from a height of
  
  38
  
  meters with an initial downward velocity of
  
  3/ms
  
  . The ball's height
  
  h
  
  (in meters) after
  
  t
  
  seconds is given by the following.
  
  h=38−3t-5t2
  
  How long after the ball is thrown does it hit the ground?Round your answer(s) to the nearest hundredth.

  I'm sorry, I am in the middle of something right now. I cannot help with any additional problems at this time.
