Radicals (Square Roots) Rules of Radicals Radicals must be completely simplified No Fractions under a radical sign No Radicals in the denominator (Rationalize the denominator)

Properties of Square Roots Product Property Quotient Property

Practice Problems:

Solving Quadratic Equations

Falling Object Equation h= height, t=time, ho=initial height

Practice Problems: The tallest building in the US is in Chicago, Illinois. It is 1450 feet tall. How long would it take a penny to drop from the top of this building How fast would the penny be traveling when it hits the ground if the speed is given by s=32t, where t is the number of seconds since the penny was dropped.

Practice Problems: How long will it take an object dropped from a 550-foot tall tower to land on the roof of a 233 foot building?
