When finding the slope it’s like finding a tangent side of right triangle because the line segment (Slope) is the steepness of the line and the two sides are equal to the rise and the run.
This week we learned about slopes and graphs, and when interpreting the graph it is hard to understand what the graph is reading. Specifically knowing if the graph is showing a positive(+), negative(-), a zero slope, or a undefined slope.
POSITIVE slope
The slope starts at the left and increases to the right
NEGATIVE slope
The slope starts at the left and decreases to the right
ZERO slope
The slope has to go in a perfectly horizontal line into the quadrant horizontal to the other.
UNDEFINED slope
The slope has to go in a perfectly vertical into the quadrant directly below or above.
Preheat oven to 350 degrees F (175 degrees C). Grease and flour an 8-inch square pan.
In a large saucepan, melt 1/2 cup butter. Remove from heat, and stir in sugar, eggs, and 1 teaspoon vanilla. Beat in 1/3 cup cocoa, 1/2 cup flour, salt, and baking powder. Spread batter into prepared pan.
Bake in preheated oven for 25 to 30 minutes. Do not overcook.
To Make Frosting: Combine 45 mls tablespoons softened butter, 45 mls tablespoons cocoa, honey, 5 mls teaspoon vanilla extract, and 250 cup apple sauce
Looking at this lab at first, I thought it was going to be a complete disaster, however, my group members and I fought through it and managed to bake up a nice batch of brownies. Each member contributed equally and put maximum effort. In the end the brownies tasted delicious and it was a great experience.
Recently I was looking back over my blog posts for Math 10, and I realized that I never did a blog posts for the different numbers groups. I was surprised about the fact that I didn’t do a blog for the number groups because it is the simplest topic but can get very confusing
CHART OF ALL THE NUMBER GROUPS;
– Natural Numbers {N} ; all positive, whole numbers, but not including zero, no negative numbers
– Whole Numbers {W} ; all positive, whole numbers, including zero, no negative numbers
– Integers {I} ; positive and negative, whole numbers, including zero,
– Rational {Q} ; can be written as a fraction ex; 5/1 = 5
– Irrational {Q} ; CANNOT be written as a fraction ex; 17/4
Last week in math we looked at functions. We learned that they are a very special relationship. For example; “a function is like a marriage because you have one spouse and only one, and a friendship is like a relation because you can have more than one friend.” Like how an input has one output.
FUNCTIONS;
In the first example on the table of values there is an example of a function, due to the input having one individual output if the 2 for example had a partner of 2 and 5 than that would make the expression a relation. In the second example the 1 (input) had an output of 4 & 5 which made the expression a relation. In the last example graphs are shown on how relations and functions are graphed. The function has a perfectly diagonal line which is not necessary, but 2 points that are equal to each cannot be perfectly vertical.
The introduction week to the Relations & Functions unit was reviewing concepts from grade 9. For example linear equations, working with a table of values, and inputs and outputs. But this week intercepts were introduced.
SOLVING AN EQUATION;
What ever intercept you are trying to solve that will mean that the other variable will be zero
ex; x – intercept = 0
then you work through the steps with the expression (BFSD) in your mind
Brackets
Fractions
Sorting (Zero pairs)
Divide
Once you remove the brackets and Fractions you are on sorting will means having numbers on each side.
