  1. Multiply and Divide Radical Expressions Notes Day 2 Book sections 7.2 and 7.3

  2. Practice Radical Operations 1. 2. 3.

  3. Practice Radical Operations 4. 5. .

  4. Simplify and rationalize all denominatorsAssume all variables are positive 6. 7.

  5. More rationalizing the denominator Hint: Multiply by a form of one which will eliminate the radical in the denominator! 8. 9. 10.

  6. 11. Find the radius of a cone that has a volume of 11 cubic inches and a height equal to its radius.

  7. 12. An object moves at a speed of feet/sec. How long will it take for the object to travel 15 feet? Now multiply by conjugate form of 1 to rationalize the denominator

  8. 13. Jim has 1 piece of wood that is 1” x ½” x 240”. He plans to cut the 240” into three pieces in the ratio of 3:4:5 to make a right triangle. How long is the hypotenuse? 3x 4x 5x Dimensions are 60, 80 and 100 but… The hypotenuse is 100” Now sub 20 in for each x

  9. 14. A rectangular prism has dimensions 5 x 12 x 10 . What is the length of the segment that connects the front left bottom corner to the back upper? 10 5 12
