Factoring Quadratics
Factoring and having x intercepts helps us find places on the graph where something hit two points or the two points where something took off. -

Quadratic Formulas
Quadratic Formulas find the x intercepts or the "zeros" and it calculates the x intercepts to find where the projectile hit the ground.
If ax^2+bx+c =0 then Xi intercepts at x = -b (Square Root) b^2-4(a)(c) divided by 2(a). -
Projectile Formulas
Horizontal:
x= (forward velocity)*t
Vertical:
y= -490t^2+ (upward velocity)*t + (starting height) For chemistry we shot the rocket at a 30 degree angle and the vertical formula equaled 1.16 and the horizontal equaled 1067. -
Angles of Launch
The projectile stays in the air 1.16 seconds and traveled 1067 cm.
