Question: `qQuery Introduction to General Themes; Examples (no summary needed) What were some of the things in this introduction that you found interesting or surprising?

*********************************************

Your solution:

I liked the fact that the introduction seemed to bring math to a more personal level by giving examples on how to utilize it in every day life.

Question: `qQuery Introductory Flow Experiment (no summary needed) Is the depth changing at a regular rate, at a faster and faster rate, or at a slower and slower rate? Support your conclusion.

*********************************************

Your solution:

The depth when the water is poured in is faster in which the rate it flows out. Once all the water is poured in, I believe it pours out quickly and then starts to slow down as the pressure gets less and less.

Confidence Assessment: 2

Given Solution:

** If you time the water at equal time intervals you should find that the depth changes by less and less with each new interval.

If you timed the depth at equal intervals of depth you should find that each interval takes longer than the one before it.

Either way you would conclude that water flows from the hole at a decreasing rate.

The reason is that as the water depth decreases the pressure forcing the water out of the hole decreases. **

Question: `qWhat does the graph of depth vs. clock time look like? Is it increasing or decreasing? Does the rate of increase or decrease speed up or slow down? Does your graph intercept the y axis? Does it intercept the x axis? How would you describe its overall shape?

*********************************************

Your solution:

It has four different lines that could represent the water flow. I would personally say the red line describes it best because it gradually goes higher and then starts to slope down which represents the fact that water was being poured into the container (line getting higher) and then water flowing out the hole with no water being poured back in (line starting to slope downward). It will intercept the x axis eventually as time goes on, depending on how big the hole is and how much time it takes to drain it. I don’t think it will ever intercept the y axis or if it’s even possible.

Confidence Assessment: 2.5

Given Solution:

** The graph will start on the positive y axis and will decrease at a decreasing rate.

The shape of the graph is the left-hand side of a parabola that opens upward. The right-hand half of the parabola does not correspond to the flow. The lef-hand half of the parabola, which corresponds to the flow, gets less and less steep with increasing clock time, matching the fact that that the rate of decrease is slowing.

At the instant the containers empties, the water will be at the level of the hole. If depth is measured relative to the hole, then at the instant depth will reach zero. The corresponding graph point will lie on the t axis and will correspond to the vertex of the parabola. **
