<p>there was no 1/sqrt(1-t^2), you put t/sqrt(1-t^2)</p>
<p>Thanks soooo much!!
wow.. relief feels so good</p>
<p>For the sin(x)=t question, I just plugged and chugged π/2, iirc.</p>
<p>Edit: π/6...</p>
<p>why is every1 debating that question? the answer is just t / sqrt 1-t^2.</p>
<p>it was on a CB practice test?</p>
<p>So looking at my TI-89's "history" (these are the ones that haven't really been mentioned yet...):</p>
<p>-There was question about multiples, where it asks something like if x is a multiple of four, then which of the following has to be a multiple of 8. I think I put something like 2x+8...but can't really remember.</p>
<p>-There was one with 7^(x-1)=49^(4-x), x=3, I put (x-1)=7^(4-x).</p>
<p>-There was one with x^2 - (6+7)x + (6*7), and it asked for a zero of the equation or something like that. </p>
<p>-There was one with two absolute values, abs(3x-2)=-abs(x+21), which was no solution</p>
<p>-And, I can't remember the problem, but I put 22.56 as an answer to something.</p>
<p>-There was a triangle problem, I think, with root(85) and root(13)...can someone confirm this?</p>
<p>-There was also a problem with cos(x)=.root(1-sin(x)^2)--I think this might have already been posted, but not sure. What was the answer?</p>
<p>There was also a problem with cos(x)=.root(1-sin(x)^2)--I think this might have already been posted, but not sure. What was the answer? </p>
<p>-the answer to that one was quad II and III</p>
<p>There was one with 7^(x-1)=49^(4-x), x=3, I put (x-1)=7^(4-x).</p>
<p>-thats right</p>
<p>There was one with x^2 - (6+7)x + (6*7), and it asked for a zero of the equation or something like that</p>
<p>-i think the answer was 6 (yay for quad program)</p>
<p>^ I agree with all the answers stated above. </p>
<p>I wonder what the curve is going to be...</p>
<p>44=800
43=790
42=780
41=760
40=740</p>
<p>and so on!!!</p>
<p>does anyone remember something about a<b<c<d<e for a standard deviation??</p>
<p>for 7^(x-1), i got (x-1) = 8-2x. because 49^(4-x) = 7^(2)(4-x) = 7^(8-2x). so therefore (x-1) must equal 8-2x. </p>
<p>i think the curve will be 43=800. or 42. who knows. its not up to us anyways.</p>
<p>I'm hoping I get above a 700. I know I left 8 blank with maybe 2 or 3 wrong.</p>
<p>what was the answer to the question about 1/f(x) it looked like 1/e^(x) but i wasn't sure.</p>

<p>I know that...(although 41 = 770 and 40 = 760 in this case) but anyway... I was only wondering what 800 would be. That'd be funny if 43=800 this time. That'd be amazing... too bad it was probably too easy for 43=800. Does it EVER get to 45=800? That would suck.</p>
<p>yea that was wat i got. A was teh answer, no?</p>
<p>i think i put D for that one (?)</p>
<p>All I know is that the answer is supposed to be the graph that crossed the x-axis at (2,0).</p>
<p>Hey guys, I have several questions.
1. What book was most helpful to prepare you for this exam?
2. Are there point reductions for answering incorrectly?
3. How many questions are there and how much time do you get?</p>

<p>Thank you, Copy&Paste, for your response.
Did Sparknotes Math IIC help at all?</p>
