We reviewed Chapter 9 concepts. We practiced finding square and cube roots, the Pythagorean Theorem to find the missing side of a right triangle, and approximating square roots. Then we practiced using the Pythagorean Theorem to find the distance between any two points in a coordinate plane.

Andrew began exercises from his Algebra I, Prentice Hall textbook, does X satisfy the equation?

For various reasons, Mrs. Megan did not feel Ben gave his best effort yesterday on his diagnostic testing. Therefore, Ben was asked to retake a section of this test again. Awesome effort today Ben!!

Assignment: Complete the assigned problems for homework.

Andrew completed exercises from his Algebra I, Prentice Hall textbook, write a variable expression.

Ben began a diagnostic test administered by Mrs. Megan.

Approximate rational numbers to the nearest 10th – We use the Pythagorean Theorem to find the missing diagonal in a square and rectangle. Then we found the decimal approximations of Square roots that are not rational. Next we reviewed that a rational number is a number that can be written as the ratio of two integers. An irrational number cannot be written as the ratio of two integers. So the square root of any whole number that’s not a perfect square is irrational and the cube root of any integer that’s not a perfect cube is irrational.

9-5 Completing the Square – We learned to complete the square by adding the square of half of the coefficient of the x to each side of the equation. Then we solved quadratic trinomials by completing the Square to completing the Square to write a quadratic equation in Vertex form.
