Notes: Move “C” to the other side and create “space” for your new numbers.Create ( )2 for you perfect squareFind the number to be added to both sides and fill in your spaces.Make your equation look like y = ( )2 + c. This will create “Vertex Form” which will be used in MT6 for graphing.

Notes: Use gravity formula - h = -16t2 + vt + c, plug in variables, and solve for “V”

0 = -16(10)2 + v(10) + 0

H=0T=10V=?C=0

0 = -1600 + 10v

1600 = 10v

V=160

160h = -16(t)2 + v(t) + c
