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.
