SP#6 Unit K Concept 10: Writing a repeating decimal as a rational number

We have been learning about finding terms in arithmetic, geometric, infinite, and finite sequences. In Unit K Concept 10, we learned about repeating decimals as rational numbers. I am showing you a more complex problem, since it has a whole number in the front. We will be using the geometric sequence formula. If you follow my steps you will find it pretty easy and understandable.

In the first step you will see my problem, which is 2.565656. Since the decimal is the 100th place, then "a sub 1" is 56/100. And the ratio is 1/100. The you will plug it in the Summation form. The Summation for will help you define the answers that you have found. Next is solving for the sum, using the geometric form. It will be simple division with fractions. That will get your sum.

SP#5 Unit J: Concept 6: Partial Fractions with Mixed Numbers

 

In this problem you will be learning about partial fractions with mixed numbers. The difference between the last to concept is having different step to take. You will have to multiply the reciprocal and having to get a certain type of denominator. Some step are the same but different order, the process is the same. In order to check your answer, plug in the calculator. 

SP #4 Unit J: Concept 5: Partial Fractions decomposition with Distinct Factors

This Unit we are learning about solving two and three system equations and understanding the linear and non linear functions. In concept five, its is about partial fractions in distinct factors. There is about seven step you will have o complete to get the answer. The partial fraction are fractions that need to be simplified and have the same denominator to be multiplied and get a matrices. After you get the matrices you will plug it in your graphing calculator, and see if you sot that step right.

SV Unit J: Concept 3-4: Martrices

This Unit we have been learning about 3 system variables called Matrices. They will have to be solve to find the exact points that go through the graph. This is a type of system that has three variables and three rows. It is solving the inconsistent and consistent systems. The system is about the row echelon form which is the answer to the problems.

The first to do, in every problem is to see if they can be factored. The two things you need to find is the triangle of zeroes and the stair case of ones. The steps are need to be followed or you will get much more than you think. Last is plugging in the numbers to the proper variables, and find each letter.

SV #4 Unit I: Concept 2: Grapghing Logerithmic

In this video I am working on a video about Unit I Concept 2. It is graphing logarithmic equations and defining the asymptote, x and y Intercept, domain, and range. This will indicate the differences of logarithmic and exponential graphs. This equation that I am teaching you, is a type of equation that can explain many things. Hopefully my way of teaching you, was not as bad as I think.

The first step is naming the variables with the prober letter. For example, "H" is switching the sign, and is plugged in at "h". Secondly is finding the asymptote, this number will always be the letter "k". If it was exponential equation, then the asymptote will be letter "h". Next, you will find the points of x and y intercept to plot on the graph. After finding the first points, then you will find the range and domain. In this case, the domain will always be (negative infinity, positive infinity). Lastly, you will find the key points by plugging in the equation to your calculator and trace the number you chose, that will give you the y-intercept.

SP#3 Unit I: Concept 1: Graphing Exponential Graphs

 

 

In this problem, I am showing you how to graph a exponential graph. This graph does not have a x-intercept because is becomes undefined when you solve. You cannot have a negative on the other side. You will have a y-intercept. You find the y-intercept by plugging in zero in the "x" value. The domain will always be (negative infinity, positive infinity). The range depends on the asymptote. You will plug in the equation and trace any numbers to get more point of the graph. This will make you get the line I have gotten. It is a really simple process, just have to know your rules. 

 



SV#3 Unit H: Concept 7 Finding Log using approximations

Feel free to watch my video by clicking here

This video was created to for my fellow partner, about a concept in Unit H. Unit H talk about logs and how to expand it and unexpanding. We are learning to how to create our own problem of concept 7. It is like a treasure hunt. You will be given clues and keys to find the answer, or code. This includes expanding, factoring, and knowing when to subtract and add. This problem is pretty simple, it explains how I got my answer and have the steps in order.

There are four steps in this problem. First of all, I am giving you keys that define a specific letter. Your answer should end up having four letters, one number, and repeated letter. Secondly, you will find the factors using the logs only. Thirdly, you have to write down the clues that are given. This should help you find the number. Lastly, is plugging in the correct log, and replacing it with the letter. The world you should have gotten is SOUL.

SV#2: Unit G Concepts 1-7 - Finding all parts and graphing a rational function

Please view my video by clicking here

 For the past days we have been learning about Graphing Asymptote. This week we are focusing on the four major asymptote which are Horizontal, vertical, holes, and slant. This indicate and expalin why we got the graph that is showing us in the graphing calculator.It is a way to find all the missing peices for the graphing equation. This is just the beginning of Graphing Asymptote.

Ms Kirch hastaught us songs to learn the method for each asymptote. Also made us create note cards, now we are explaining what we think we know. My equation is a slant asymptote, since the top degree is bigger than the bottom degree. I have shown you how to find the domain, x and y intercept, holes, and graphing it. Hopefully i explained it right, if not please fill free to correct me.

SV#1: Unit F Concept 10 - Finding all real and imaginary zeroes of a polynomial

In this video I am verbally explaining how I got my answer. This is a concept 10 question, it is about finding zeroes and the real factors of the question. There are three main steps that need to be done to get the answer that you need. The three steps are finding the PQ'S, finding the repeats of signs, and find the y value.

First of all, you will define all the PQ's  because those are your numbers that will be used in the synthetic division. After you find the PQ's you will multiply them. They could be whole numbers or fractions. Next, find the switches for f(x) and f(-x). That will tell you how many positive or negatives there are. Lastly is doing synthetic division. That will give you the answer, always factor if you can.

SP#2: Unit E Concept 7 - Graphing a polynomial and identifying all key parts

Graphing Polynomials is a way to find how the center of the graph will look like. My graph is not accurate because it does not include the extrema. This only shows you where and how many curves or bounces it has.

Finding the zeroes is finding the curves of the center of the graph. The degree represents how many zeroes you should have. Also you will have to find the end behavior. The is knowing the degree and leading coefficient. This will tell you if its up hill down hill or other type of graphs.

SP#1: Unit E Concept 1 - Graphing a quadratic and identifying all key parts

This image is on my Standard form equations. I am solving for many multiply answers to graph it. I get the parent function, vertex, y-intercept, axis, and two points. That way I can show it on a graphing grid.

The problem is about get a standard problem and solving it and graphing it to get the parent function equation. One of the things you need to focus on is solving it after you find all the important points. Foe example the vertex and y-intercept. Also how to graph it and graphing it correctly. You need to know ahead of it is a minimum or maximum.
