Task 1
Task 1
Write an equation to represent this story.
- Let w equal the water left in the tub
- Let t equal the time that has passed, in seconds
Try really hard to write the equation.
After you write your equation, click this link to check your answer.

Task 2
Task 2
Calculate how many seconds it will take to drain all the water out of the tub.
Task 3
Task 3
Click this assignment button to open up a Google Spreadsheet called “Draining the Tub”.
You’ll notice that I have not put any values in the table.
Decide what values you want for t (time, in seconds) and then calculate the values for w (water left in the tub, in gallons).
Task 4
Task 4
Create your graph. Think carefully about the scales on the axes.
Be sure to include
- Graph Title
- Label for the x-axis (the horizontal axis)
- Label for the y-axis (the vertical axis)
Optional Task 5
this is going to be very difficultOptional Task 5
You probably created a scatterplot because that is the kind of graph we have already made.
A line graph would better represent this data since the water drains out continuously.
On the “Data” tab, and "Chart Type" option
- change your graph from a scatterplot to a line graph.
- experiment with the check boxes to create the graph you want.
Turn in your work if you finish Task 4 (or Task 5).
