We are getting very close to the end of 2nd quarter. Christmas break is coming upon us quickly and then we don't have much time left after the break.
PLEASE GET YOUR GRADE UP BEFORE THE BREAK!! Come see me and I will help you.
This is what we are doing this week...
Geometry:Dec 6th/7th Day 12We took notes and discovered how to find the sum of all the interior angles of any number sided polygon. The formula is (n-2)180. We used that formula to find the number of sides given the interior angle sum and also to find the measure of one of the angles of a regular polygon. Then we discovered that the sum of all the exterior angles is always 360 degrees no matter how many sides the polygon has.
HOMEWORK: Pg 407 #13-30, 35-43 (skip 42)
Dec 8th/9th Day 13We will practice finding the perimeter of any polygon. The perimeter is just the sum of all the sides (every side added together). In class we will work on a perimeter worksheet.
HOMEWORK: Pg 48 #7-8, 11, 19-24, 29-34
Dec 10th/13th Day 14This will be our final day of new material for our Quadrilateral/Polygon Unit. We will learn the formula for the amount of lines of symmetry of a regular polygon which is n=l (meaning the number of sides equals the number of lines of symmetry). We will also learn the formula for finding the number of diagonals in any polygon. This formula is n(n-3)/2 where n equals the number of sides.
HOMEWORK: Quad/Poly Test Review
Algebra II:Dec 6th/7th Day 12Today we finished the notes of section 7-3 in the textbook on adding/subtracting radical expressions. At the end of class we took a mini-test on sections 7-1 to 7-3 to make sure we are understanding everything so far.
HOMEWORK: (for A Day) Pg 382 #3-36 (m3, skip 24)
Dec 8th/9th Day 13We will learn how to solve problems with rational exponents, meaning the exponent or power is a fraction. This is section 7-4 in the textbook.
HOMEWORK: Pg 388 #2-60(evens), 65,-71 (odds)
Dec 10th/13th Day 14We will learn our final sections before our Chapter 7 Test...section 7-5 and 7-8. Section 7-5 deals with solving problems with equations under the radicals not just one term. Section 7-8 teaches how to graph radical functions.
HOMEWORK: Pg 394 #1-39 (odds, skip 31,33)
Keep working hard and let's make it a GREAT WEEK!!!
