height = at^2+bt+c. substitute any three values of height and t to find a,b,c. and then use those values to find out t for height = 30 meters

wait, this is best fitting. hmmm. I think you have to follow a different procedure for this.

If you havent, then the best thing would be to use the method I described. use t = 0 , 2 ,4
anonymous
  • anonymous
okay so its B
anonymous
  • anonymous
are you getting different values of a,b,c if you are choosing different heights and t?
anonymous

i really dont understand
