Yesenia Though about this year

This year math help me get a tastes of what to look froward for next year and college years. No i don't want to send my letter to the company. I think that for next year you should start Blogger early. So that the kids can get the hang of it.

The overall task to today was to grap the new SA fuction and finding the miniumun. I use a graping calculator to determine the minimun surface area.

It was necessy because it help us and the reader understand how to change the hight without change the voulme

Lesson 5 Exit Slip

The first function in the table is y1=4x^3 and the second function is y2=7x^3. They're both quadratic functions.The first column contains the values for the independent variable x. The domain of these values ranges from -25 to 25, making the scale 5.The x-values were then substituted into the function y1. I notice as the x-values increase the y-values decrease. The same applies for the function y2, as the x-values increase the y-values decrease. (0,0) is the vertex and it is also the minimum.

Lesson 9 Exit Slip

This new surface area function will be use in the PABT in ways that it will help me get the height of my can and to be able to simplify any function faster. The ultimate goal of findind this new fuction was when we need it to take this and apply it to my own obat in order to subtitue my hight into SA formula for my can.
I can visually take this funtion and show the relationship between the area and the surface area by changing the height and subsituting it into the SA formula

Lesson 8 Exit Slip

Yes it is necessary to combine two formulas in order to simplify your formulas through a step by step process.
what I would have to do is combine the surface area formula along with the volume of a circle.

Important of today LESSON

From today lesson I thought that the important was learning that even if you change the height of the can you can still get the same voulme you start with. Also if you change the radius you can still get the same volume you start with. As long as you use the volume formal.
I use google document sheet and spreadsheet as well as a calculation. It help my keep my work togeter the document and the spreadsheet. The calculation help me multipul faster. This is also how using these mathematical tool help me make my life easier will doning this job.

My Can Volume and SA Cale

Today my group and i helped each other by helping eacher measuring the radius and the height of our chocie Can. I was able to accomplish, finishing both of my tables in class. I didn't learned any skills but i did practive a skill that i haven't proctive in a long time. I don't know how i well use these skills outside of school, but i do know that i will use it throughtout bu PBAT. A question that i have about what i have accomplish well be why is it that my measurments only changed from 8.2 to 8.1 when it came to finding the diameter and from 3.2 to 3.1 when i found the height ?

The curvature of y2, compared to y1, is neither narrower or wider, but it is reflected on x-axis.

Compared to y1, y2's graph is shifted vertically. We see this in the graph by noting that the minimum point of y1 (0,0) is also the maximum point of y2.


There is no horizontal shift because the line have the same pattern horizontally. The minimums line up at x=0.

Compare and Contrast two Fuctions

Things that were the same when it came to the categories in both graphing and functions was that both of them has a 0 highest degree term and 0 constant term.
Something that was the diffrent was that one equation was negative and the other one was postive. Both equation are the same but the one that had a postive highest degree term face up and the one with the negtive highest degree term face down.
In my table i want up to 22 meaning that the first 12 number with the postive highest degree were postive untill it got to 13 that it was zero then from 14 to 22 it was negative. The one that had a negative highest degree term start off neagtive after it hit 13 it was zero then from 14 to 22 it was postive.

Question - What was one major idea that you learned today?

Answer - How to use a spreadsheet.

Question - What is one major problem you has had today and how would you, by yourself, handle it the next time?

Answer- I didn't have problem i got it right away.

For Wan and my team

Hey guy, I well not make it to school today March 18,2010 but I hope that my team can be done with their parts of the paper by today. I will also be done with mine today. We can keep each other up date through our gmail if any thing. One more thing i left my notbook in school so i will need to finish the table in school tom. But everything eles I hope to be done by today. Thanks

progress update

When x is 7 I added 10 to get the height. Then to get the girth I multiple 2 by width plus 2 by height. After I found the girth, I moved on to the length which I subtract the total – girth. Then I found the volume by multiplying length by height by weigh. Y= (165-(4x + 20) – (x+10) – x. 2. We found the maximum point then we graph x= height and the y= volume. 3. I don’t get what you are asking me in question number.

When x is x you need to add 10 to get the width The height stady the same as the x. Then to find the girth you need to multiple 2((x+10) + x) = Girth. To find the length you use either 130 or 165 i am going to us 130 so then 130 meaning the total i'll subtract it from 2((x+10)+ x) which
i sublifia it to 4x+20. Then i'll will find the volume by doing (total - (4x+ 20) by(x+10) by (x) and that should give you your volume.

When we graph we use the x for the height and the y for the volume. The way we organizes the date was by names FedEx and UPS. Then in the graph we organized it by color and fuction.

My Group and I achievement

I feel that my group and I have achieved as a team today. We completed all four tables. But we have not establish the maximum volume, it doesn’t mean that we haven’t found it just mean that we have not located it on the graph as of this moment but am share that my group and I well find it on Thursday. The designs my group and I choice were the square prism and the rectangular prism.

Questions? Comments! and Concerns ~_~

How are we going to start this project?
What is it going to teach us?
Are we going to use this more offten?

Commuity box maker

I'm new to Blog and i don't know what to do my teacher made be create this blog so that i can get febacks from people that know about math. This project has to do with how many wight and the size that is provied by the two biggest international priority which are FedEx and UPS to be able to send these packaging.
