in this week of math I learned the equation y=mx+b, that is the y intercept form the y stands for the output number the m is the slope the x is the input number and the b is the y intercept. this equations tells you a lot about the slope of the line and how […]
This week we learned how to find the domain and range of a graph. The domain is the lowest to highest x values. And the range is the lowest and highest y values. To read the domain you go from right to left, for the range its down then up. for example: to find the […]
this week I learned how to factor polynomials. There is a pattern that you could use to help solve equations with factoring polynomials. You always want to add more brackets to the equation. for example, if you wanted to find out what a is, you would use this pattern. x^2 + ax + 20 anything […]
polynomial patterns there is a specific pattern for some simple polynomials that can make the equation easier and that can help you figure out the response easier. REMEMBER** this pattern only works for SIMPLE equations. for example, (x-3)(x+5) usually I would do the distributive property which would look something like this: x x x = […]
This week in math I learned more about Polynomials, I learned about the negative law, it flips the entire equation. for example: (2x+3)-(3x+4) You would use the negative law here 2x+3-3x-4 the positive 4 becomes negative -x-1 another example (6x^3 + 2x^2 – 5x + 2) – (2x^3 – 4x^2 + 6x – 7) […]
In this week I learned that the angles of depression and the angles of elevation are the same on a triangle. ex: to find the angle of depression, you must use Pythagoreans theory to find c. 15^2 + 15^2 = c^2 225+225= 450 the square root of 450 is about 21. we know that there […]
In this week I learned how to use scientific notation. I also learned how to put scientific notation into a calculator to help with my calculations. Scientific notation is used when you want to breakdown a very big number. The first number has to be under 10 and over 1. For example: 982 000 000 […]
For this week in math I learned how to find out the number of possible factors of a number. For example, if you want to find the numbers of factors in 12. step 1: break down the number using prime factorization. step 2: use the exponents rule Step 3: Add 1 to each exponent, *REMEBER […]
