<p>im sorry i meant 2x-2 you’re correct i fixed it^</p>
<p>i think i got 12 for the folding too proto</p>
<p>and mycoalwin i think your friend is wrong. it said they were two calls independant of eachother, whats the chance one will be local one will be long distance. alls you had to do was multiply the two which was 2/3* 1/3 = 2/9</p>
<p>sirena, i just graphed them all and found the one with two zeroes. idk which one it was.</p>
<p>@sirena It’s C</p>
<p>sirena it was E i dont remember the exact answer but it was two difference of two squares like (x^2-9)(x^2-1) or something like that?</p>
<p>Does anyone actually remember the question for the folding? Like the exact question?</p>
<p>oh crap. i think i missed the folding one. i think i found it in inches and multiplied it by 12, not divide!!!</p>
<p>@pianoman, sorry, but you’re wrong. That has 4 real roots, as (x^2-9) factors to (x-3)(x+3), and (x^2-1) factors to (x-1)(x+1).</p>
<p>^ Wasn’t the answer around 10 feet after the conversion?</p>
<p>Also, wasn’t one answer that there must have been two zeroes?</p>
<p>yeah its C</p>
<p>The paper started at .03 inches, doubled every fold. it asked for 12 folds, i believe…
my thought was: .03 x 2^12 = 122 inches
122/12 = 10.2 feet</p>
<p>good old dimensional anlaysis:)</p>
<p>@thankyou4flying, I also got 10 feet.</p>
<p>ahh i misread the problem you’re right! i did which has all real roots</p>
<p>Was the answer to the Depth one something like 13.4… or like… lmao I don’t remember, but SOMETHING point 4.</p>
<p>^^^^^well if there was an answer choice of 1474.56, i think i put it :(.</p>
<p>I hate STUPID mistakes!!!</p>
<p>what was the answer to the 3 dimensional cube question. i think u had to find volume?</p>
<p>Was the period 4pie for the period question?
and for the one with the trig and it asked for the max minus the min. Was it 8.4?</p>
<p>@ Sirena, wasn’t it 8.4?</p>
<p>2pi, proto.</p>
<p>got 8.4 for the difference.
I think it’s already been settled here that it’s 2pi because of the absolute value. if you graph the equation in your calculator, the graph repeats itself every 2 pi.</p>
