Week 9 – Math 10 – exponent laws

Kiana on

exponent laws

  • like terms— exponent stays the same but you add the coeffecient
  • multiplying bases— multilply bases, add exponents
  • dividing basas— subtract exponent, divide coefficient.
  • zero exponent— equals to one
  • negative exponent— to make a negative exponenet a possitive exponent find the reciprocal.
  • exponents with brackets— mulitiply exponents, power coeffitionts and constants

Mon but dans le cours de FRAL10.

Kiana on

My goal for this course is to get better at discussions in class and for marks. To obtain this goal I will practice the conversation in my head and search up more words that I don’t know so that I wont be confused when I do the discussion. I will practice participating more in class discussions so that I have more practice for the ones that are marked. It is important that I do this so that I can practice having real conversations in French.

Week 5 – Math 10 – Finding a missing side of a triangle

Finding a missing side of a triangle

  • To find the missing side of a triangle you need to have the length on one side and an angle.
  • you name all the sides and find out if you need to use sin, cos or tang.
  • to make the equation you take the angle and put is after your sign then put equals sign for the variable and the length of the side.
  • depending on if the length is on the top of the fraction or not you will multiply or divide the length by the sign of the angle.
  • once you do this you will have your missing side.

Week 4 – Math 10 – Naming sides of a triangle

Kiana on

Naming sides of a triangle:

  • In a triangle there are three types of sides: Hypotenuse, opposite and adjacent. Naming these sides can help you find different ratios and can help with the equations of those ratios so its very important to identify these sides every time.
  • an example of how to find the hypotenuse is you find the square in the corner and whatever side is opposite to that square is the hypotenuse.
  • Right Triangle: Definition, Properties, Types, Formulas
  • An example of how to find the opposite side is that the opposite side is always opposite to the degree sign.
  • Whatever side is left is always the adjacent side.

Week 3 – Math 10 – Scientific notation

Kiana on

scientific notation

  • scientific notation is used represent a very long number in a shortened way. For example 19 000 000 would become 1.9 x 10 to the power of 7
  • To convert a large number into scientific notation you count how many times you would have to move the decimal over until you reach the last number. With the number you just came up with you will times the decimal version of the large number with 10 to the power of the fist number you came up with. I find this method a very useful method for me.

an example of a way to do this with positives is shown in this image:

another example but with negatives:

Week 2 – Math 10 – GCF

Kiana on

The GCF

This week in math I learned how to find the Greatest common factor of two different numbers. I learned two different ways that i could find the GCF:

  1. Use a factor tree.

To find the GCF using the factor tree you take the first number and you write how you multiply to get the number. If the numbers you chose are prime numbers then you circle that number. If the number is not a prime number you repeat the process until you get all prime numbers. With each set of prime numbers you would cross out all matching numbers and place them somewhere else on your page. multiply these prime numbers together and you have your GCF

Ex:

2. division table

To find the GCF using a division table you must take the number and divide it by a prime number going from least to greatest. Repeat this process until you are left with a 1. With each set of prime numbers you would cross out all matching numbers and place them somewhere else on your page. multiply these prime numbers together and you have your GCF.
