Question 1020997
Hello, I am having trouble with a Word problem/quadratic equation. "A company manufactures high-powered fountains that can be used to create water shows set to light and music.  The company makes 3 models, each can launch a vertical stream of water to a different height, as indicated in the table below        .             ________________________Model A    Model B      Model C
Height(ft)-----------      -77---------100---------240
time to fall(s)----       --2.194----    ?     ----  ?
Initial velocity (ft/s)----70.2---------?-----------123.9 
-------
h(t) = -16t^2 + Vot + Ho
------------
Using Model A DATA:
77 = -16(2.194)^2 + 70.2(2.194) + 0
------
Using Model B DATA:
100 = -16t^2 + Vo(t)
------
Using Model C DATA:
240 = -16t^2 + 123.9t
Solve for "t"::
t = 4 seconds
