Forensics. The distance a car travels even after the brakes are applied can be described through a quadratic function. But there is also the reaction time, the split second before the brakes are applied. The total distance is known as the stopping distance and this segment analyzes the quadratic function. This is an equation that can be used by accident investigators.
Algebra Applications: Quadratic Functions is a free educational video by John Santiago.It helps students in grades 9,10,11,12 practice the following standards HSA.REI.B.4.b.
1. HSA.REI.B.4.b : Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b..
