<p>What was the answer for length of hair question? I read all posts in here and no one seems to have problem with it? Was it 5 because 9-4=5??? The graph looked really weird to me because the question said it’s a line graph</p>
<p>
</p>
<p>haha. I just did… 3/4 = 10/x. 40/3. But I wrote it out… “13.3”.</p>
<p>
</p>
<p>Five is correct. :)</p>
<p>Well if it is really so bad, the curve will be easier. I tried to work out the exact function but then realized they pretty much just gave you the answer.</p>
<p>xatuaa, i cant explain it to yyou but i’ve heard the function answer was 24, not 12</p>
<p>I got 40/3 as well.
It seems right to me.</p>
<p>And for the hair question, I got 5 as well. Just create a linear function and then solve for the y intercept.</p>
<p>graph was weird because they used zigzags so that the answer wasn’t obvious–>they didn’t give you the bottom portion of the y-axis.</p>
<p>Yes it was 5.</p>
<p>here’s confirmation of the 40/3 problem, </p>
<p>I made a quick proof here : <a href=“ImageShack - Best place for all of your image hosting and image sharing needs”>ImageShack - Best place for all of your image hosting and image sharing needs;
<p>that’s what i got monoclide, but people keep challegning it</p>
<p>and the hair answer i got 5 as well</p>
<p>The hair was easy once you realize that the graph was truncated. Just set up a linear equation y=2x+5 if I remember correctly, so at zero days it was 5.</p>
<p>For the 40/3 problem, al lyou had to do was use the proportion thingy…</p>
<p>I did 10/x = 3/4 and got 40/3</p>
<p>monoclide: wait, but the ratio 3/4 was for the AREAS of the triangles.
don’t you have to square root it to get the ratio for the sides?</p>
<p>i got my 11.5 that way. :/</p>
<p>monoclide, did you get 5/12 or 2.4 for that one problem?</p>
<p>
</p>
<p>It was not even a hard question. They wouldn’t make you do superserious work. It just a simple proportion problem.</p>
<p>
</p>
<p>Which problem was that?</p>
<p>Would somebody please take another minute to look at my query >< I still have a heartfelt feeling that it’s possible :|</p>
<p>anybody have the geometer’s sketchpad??? we could confirm it on that.</p>
<p>Yea easiest thing to do was to put that equation into your calculator as Y1, head over to the table and look which point was there</p>
<p>For the one where everybody got 40/3, is 13.3 acceptable? I have no idea why I didn’t put it in fraction form lol.</p>
<p>yeah it is decroo</p>
<p>monoclid, it was somethin like this:</p>
<p>y=3, x=(5/4)</p>
<p>3/(5/3)=2.4</p>
<p>nvm, I was siking myself out. 40/3 is RIGHT! Cheers!</p>
<p>I just did it by hand, you can plug in 3 for area of the top, 4 for the area of the bottom, and solve it by plugging in</p>
<p>
</p>
<p>I put the same.</p>
<p>Of course it will be accepted. Otherwise, they better prepare to have thousands of people calling and screaming.</p>
<p>
</p>
<p>I don’t ever remember a question like that. Was it on the experimental section?</p>
