Exit Slip

It is necessary for us to combine the two formulas because the height formula is necessary so the surface area formula could be fully generalized. If I had to do this to my can I would have to find the height formula first and the fully generalize the surface area next by replacing the height with the formula.

The overall task of the PBAT is to make the can have the same volume but with using less material. We have to change the radius and the height also changes when the radius gets higher. The surface area also decreases when the radius changes but the volume stays the same.

Exit Slip

We changed the radius for our own cans and then we found the height. The matematical tools we used today was a calculator. This was helpful because with the calculator we were not going top make a mistake that easily. It also made my work easier because I didnt have to think for my answer.

I helped Alex find his diameter and radius. I also helped him calculate his surface area. I was able to acomplish finishing my volume calculations and my surface area calculations. I was also able to find my diameter, height , and radius. I have no questions and I really dont know how I would use this outside of school.

Exit Slip 11.1

both columns of the tables decrease then increase

In the Graph y2 is more narrower than y1 and y1 is more wider. There is a vertical shift because there is a large gap between them. There is no horizontal shift.

We had to add another column and then were it says C1 we write the equation we want to use. In C2 we write equation again. The equation I used was y=-3x^2. After that I just drag the line so the answers to the equation would appear. Then I had to compare the two functions and They were similar because just the answers were the same thing but just one of them were negative. One had a curve going up and the other curve went going down.

I learned that writing the equations give you the answers faster then wen we do it on paper.The major problem I had was figuring out how to write the equation so it could give me my answers.

progress update 2

i generalize the table by putting x for x and when x is x so is the height for width i had to put +2 because my design was w=h+2 and then to find the girth was 4x+4 and for length i had to subtract the girth from the total and gave me 126-4x. For the volume i got (126-4x)(x+2)(x) and i got that by putting the legnth, width and height together. For my y axis i decided to go up by 600s and i got that by looking at the points in the graph and looking at the highest point and i did it up to 22800. for my x axis i went from -8 to 30 skipping by 2s. Then i got my maximum points by using the calculator and it gave me the maximum value for the fed ex express graph. when i compared the graphs for the maximum values there was something in common which was if the width is closer to the height than the volume is greater but if the width is further than the height than the volume decreases. Ifound this by putting all my information in one table and comparing the height the width and the volumes.

progress

the group progress is good i finish graphing the points for fed ex express. Ifound the points by putting the volume equation into the calculator which gave me the points. The volume equation I got by generilizing everything. For the graph i had to first look at the points in the calculator to figure out how much would my (y) axis would go up by. the figure out the same thing for the (x) axis. I ended up going by twos in the (x) axis and going by 600. I also found the maximum volume for all of the graphs and now all i have to do is put all my calculations together.

homework

my progress is good because i finish doing all 4 of the calculations for fed ex express and ups all im doing is finishing graphing the numbers for the fed ex express.

Community Box Maker Project

1.Why do we have to present the project to a panel?
2.Why do we have to make a group report?

The project looks hard and i am not interested in the project it looks like it is going to be hard.
