2. Notes: Move “C” to the other side and create “space” for your new numbers. Create ( ) 2 for you perfect square Find 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. x 2 + 6x + ____ = 72 + ____ (x + ____) 2 = ____ y = (x + ____) 2 - ____ 6/2 = 3 3 9 81 3 81 x 2 – 5x + ____ = -6 + ____ (x + ____) 2 = ____ y = (x + ____) 2 - ____ 5/2 = 2.5 2.5 6.25.25 2.5.25

12. Notes: Use gravity formula - h = -16t 2 + vt + c, plug in variables, and solve for “V” 0 = -16(10) 2 + v(10) + 0 H=0 T=10 V=? C=0 0 = -1600 + 10v 1600 = 10v V=160 160 h = -16(t) 2 + v(t) + c

14. Notes: Draw a picture of what is happening. You know velocity (160), you must figure out how many second it took to get to the maximum height. Plug in and solve. T=0 T=10 T=? (Maximum height) 5 h = -16(5) 2 + 160(5) + 0 h = -400 + 800 H=400 400 h = -16(t) 2 + v(t) + c
