# Week 10 – Math 10

This week in math 10 we learned about Function notation. Function notation is used to replace the mapping notation.

Examples of function notation:

1. g(x) = 6 – x^2

g(4) = 6 – 16

g(4) = -10

2. g(x) = 6 – x^2

g(-6) = 6 – 36

g(-6) = -30

# Week 8 – Math 10

This week in math 10 we learned about X and Y intercepts

When determining the X intercept(s) you must turn the Y into a zero and when determining the Y intercept(s) you must turn the X into a zero. Here are 2 examples of both.

X-intercept(s)

1. y = 2x – 8

0 = 2x – 8

8/2 = 2x/2

X = 4

2.  3y + 2x – 12 = 0

2x – 12 = 0

2x/2 = 12/2

X = 6

Y-intercept(s)

1. 2y + 3x – 12 = 0

2y – 12 = 0

2y/2 = 12/2

Y = 6

2.   2y = x^2 – 60

2y/2 = -60/2

Y = -30

# Week 6 – Math 10

This week for math 10 we learned how to factor trinomials. So I will be teaching you how to do this with 3 examples.

Ex 1.             x^2 + 10x + 16

Answer        (x + 8)(x + 2)

I got this answer by starting with the constant which is 16. You must know what 2 numbers work 16 and 10x for this example 8 and 2 works because 8 + 2 adds to 10 which is 10x and 8 times 2 is 16.

Ex 2.                  x^2 – 2x – 15

Answer.            (x – 5)(x + 3)

Ex 3.                 x^2 – 2x -24

Answer.           (x – 6)(x + 4)

# week 5 – math 10

This week in math 10 we are learning more about polynomials and I will be showing u how to use patterns to find the answer faster than distributing.

example:

(x + 4)(x + 7)

so in this example you have to distribute but in this case there is an easier way.

First you must multiply the x by the other x and you get x^2. second you add 4 plus 7 and you get 11x. So now you have x^2 + 11x. lastly you will multiply 4 times 7 and you will get 28.

Answer: x^2 + 11x + 28

# Smart Goal Reflection

1. My goal for the past 2 weeks was to get a six pack because it would look cool and help with sports.
2. Unfortunalety I did not achieve this goal because It was hard to find time and doing this goal is hard to achieve in the 2 week range.
3. The most challenging part of achieving my goal was finding time to do it.
4. Next time I will do better to find time to achieve my goal.
5. I plan on continuing my goal when I have the time because it will help me with sports which I love to do.

# Week 4 – Math 10

In this week of math 10 I will be showing you how to solve for a triangle. This will include finding the sides of the triangle and the angles.

In the picture show down bellow you are given 2 sides: side A-38 and side B-29. You know have to figure out what other sides and angles you need to solve this triangle. in this case side C, angle A and angle B are left. In this example bellow I have shown all the information needed in solving a triangle. It wont let me rotate the picture.
