4/18 Applied Geometry - Arc Length & Sector Area

Today we continue with circles. The video above shows how to find arc length in a circle.



The video above gives an example of finding sector area. Students will take some notes over some additional example problems in class and then work on two worksheets for practice.

4/17 Algebra 1 - Solving Polynomials in Factored Form

Today we started to move towards solving quadratic equations by factoring. We looked at polynomials in factored form and gave their solutions. It is a fairly simple concept. For example, the solutions to (x-3)(x+4) = 0 are x=3 and x=-4. You simply switch the signs. For (2x-6)(4x+8)=0, the solutions are x=3 and x=-2. You switch the signs of the numbers and divide by the coefficients on the x's. We are basically doing the algebra in our heads. For more examples, view the PowerPoint Presentations here.

Homework:
done & graded in class: page 600, #'s 20-42 even & 46-48 all

4/17 Algebra 2 - Combinations

Today we will continue with our study of counting principles to lay the foundation for calculating probability. In the previous lesson, we worked with permutations, orderings of a number of objects. Today we will focus on combinations, choosing a set of objects where order is not important. To see some examples of both, click here. To see some more problems involving permutations and combinations and their solutions click here.

Homework:
