<p>i did… the FR was harder on B…</p>
<p>@CHEMFROMMA: I don’t know if they’ll catch it or not. It may depend on who reads your papers.</p>
<p>Each of your free response questions will be read by two different readers, and for the most part, readers will stay on the same questions throughout, so it’s unlikely that the same reader will read more than one of your questions.</p>
<p>What would have to likely happen is that the reader would have to recognize the work for the question that they are reading is that of another question. Since the readers usually only read one question at a time, this means they would have to recognize the question from seeing it earlier (say at this particular point in the year).</p>
<p>The good news is that if your reader is from a high school, those readers are all (maybe only almost all? Not sure if there are exceptions…) AP Calculus teachers who likely looked up all of the questions for their own knowledge of the exam. If your grader is from a college, not sure that would happen.</p>
<p>But especially this year, I think you have a fair shot of that happening, especially with the nature of the mentioned questions. If you actually answered question 1 in the question 2 spot, folks would be wondering why we care how far Caren is from home when she should be waiting in line at a rock concert. (And who brings a calculator to a rock concert anyway?)</p>
<p>lol, thanks Math Prof… hopefully, they do catch it… whatever, lol… I already have the credit for the class regardless, I took calc I and calc II at a local college at the same time…
haha,
I bring calculators to rock concerts, oh ya!</p>
<p>wait so what is the exact answer to 4c?</p>
<p>Has anyone here done the Form B test?</p>

<p>I think I got 2970 too… I mean, it says “the
cost to produce a portion of a cable that is x meters from the beginning of the cable is 6rootx dollars per meter.” If the sale is 120x…and profit = sale - cost, it has to be 120(25) - 6root 25</p>
<p>No, the answer is 2500</p>
<p>The question said that 6root(x) was the cost to produce meter x of the cable. So, for a 25 meter cable, 6root(25) = 30, is only the cost of the 25th meter. You have to take into the account the other 24.999999999 meters to calculate the true cost of the cable. So, you must integrate 6root(x) from 0 to 25 and subtract that value from 120(25).</p>
<p>I got worked out FRQ’s for yall, enjoy!</p>
