I+have+a+question+on......

This page is for those questions on whatever that we have between classes. Here is one I got today:

I'm just a little confused as to what is supposed to be done on this worksheet. Are we supposed to solve the problems using the different strategies, or are we supposed to give definitions of the strategies?

I'm assuming we are talking about the worksheet attached to the article. If so, the top part is information regarding the common types of R & P tasks. The bottom half is where you can fill in examples and explanations for the 4 strategies once you read the article. Thanks for clarifying.

Also I was trying to work out what would be a good deductive justification to that problem we were working with as practice for the quiz and I was wondering if you could look at it.

For the work I displayed: 12mm is the given constant rate 20min

12mm = .6mm so .6mm/min = unit rate 20min 1min

.6mm x 50min = .6mm x 50 = 30mm 1min

Then my written explanation would be: The candle is burning at a constant rate of millimeters burned over time. Once you find how many millimeters the candle burns per minute, the unit rate, you can find how many millimeters the candle burns for any amount of minutes. I'll let you guys respond to this question. Offer constructive comments not just "Looks good to me". Indicate explicitly why it looks good or what is missing. I think this is a good question for all to consider.

I think that if maybe you add why you know it's burning at this constant rate. like for example if you add. i know that for every minute the candle is burning, the wick is burning .6 mm therefore at this constant rate if we need to determine how many millimeters the candle burns for X amount of minutes we can multiply the x minutes by the constant rate of .6 mm/minute. Maybe this one still needs revision but by adding some of the ideas i feel that it may be clearer? what do you think?

The response above is a helpful example of how to write a deductive justification for Task #1. Another way of phrasing it could be- (I wrote this)
==== Since the candle has burned 12 mm in 20 minutes, it burns at a constant rate of 0.6 mm in 1 minute. Therefore, in order to find how many millimeters the candle has burned for any given number of minutes, you need to multiple 0.6 by the number of given minutes (x) in order to find how many millimeters the candle has burned. ====

(Also wrote this) ==== I also have a question regarding Task #3. In reviewing our homework, I cannot seem to find how to correctly write an equation for part b. In every other task the candles are burning at constant rates except for this one. The only equation I have come up with is y = 168/x or a = 168/b. I know that the slope is negative but every y coordinate decreases by a different amount. For example when x = 1, y=168 and when x = 2, y = 84 (so 168-84 = 84), but then when x = 3, y = 56 (84-56 = 28). Since I can't simply divided the rise over run because there is no constant rate for how much each y coordinate is decreasing, I am stuck on how to find an accurate equation for the problem. Any responses on how you may have figured out an equation would be very helpful! Thank you! ====

We hit this one in class and now know it is inversely proportional. Cool. I was just wondering if anyone knew what format our papers needed to be in. If it needed to be double spaced and such...I cant find anything in the syllabus. Our writing assignment needs to be in 12 point font, double spaced with 1 inch margins and between 1 to 2 pages in length. The rubric is on the bottom part of the page of our assignment. Can someone remind me if we are supposed to write it out as a formal paper or if we need to write #1. and answer that question and then #2. and answer that question for both the before reading and after reading. I remember this being asked in class but I can't quite remember. I wrote mine out as a formal paper, and just answered each question. I have a question on the Unit Review worksheet. I have worked on it for a while now, and I cannot seem to find a linear equation for all questions: 1,2, and 3. For instance, on question 1, the pig doesn't gain the same amount of weight each month so I don't know how to write the equation. It also talked about inverse variations, but I don't know where to go from there!!

I'm not sure all 3 problems are linear as I read the instructions. And in real life, we don't have "nice" data that increases by __exactly__ the same amount each time. Keep at it! Dr B
