The important concept of todays lesson was identifying the relationship between length and height, and finding the height of our cans by using the givens for the volume of our cylinders.
We used a calculator as our mathematical tool to help us divide decimals. Our aproximations are more accurate when we use a calculator because the pi is more exact.

Comparing the two functions on the board.

The graph shows two functions. Both functions make a curve and make a mirror reflection. In comparison to y1, y2 is more narrow, and is located at the bottom of the graph. There is also a vertical shift between both functions. Function y2 starts at [-10, -600} and ends at {8, -390}. Function y1 starts at {-10,400} and ends at {8,300}.

TODAY WE COMPARED TWO FUNCTIONS BY SETTING A TABLE THAT SHOWS THE DEGREES OF EACH FUNCTION, AND EACH OF THE FUNCTIONS. THE TABLE WAS COMPLETED BY CHECKING IF THE DEGREES MATCHED ANY OF EXPONENTS BETWEEN YOUR TERMS

My D/E Slip

1} I learned how to create a Spreadsheet on Google docs. I learned how to make a graph and edit them.
2}The only problem I had today was clicking on the smaller box on the bottom right of each cell, correctly in order to create the consistent pattern of the table.

My progress so far!

I generalized by following the same rules and using variables to make things 5 times as much and 3 times as much. I can use any number to make the box bigger or smaller this way. When it was time to graph I took a look at my tables to figure out my minimum and maximum values. I then planned a scale and checked it on a calculator by graphing the function and checking the graphs appearence. I adjusted the window settings by changing the X and Y scales.
When organizing my data into different tables we simply had a different table for each of our functions. Each table had the X and Y values.
Our results showed that the function (130-4x)(x)(x) has the maximum valume out the four funtions that we graphed. The maximum value was 20342 cubic inches. This box was 1 time as big.

my classwork and homework

i wont be able to complete the online assignment because i have not completed classwork and cannot find the sheet with the table and all that good stuff.

Picture Reminder

we were all supposed o upload an appropiate picture, but apparently we have forgotten to.
