<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>
</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.
- What book was most helpful to prepare you for this exam?
- Are there point reductions for answering incorrectly?
- How many questions are there and how much time do you get?</p>

Did Sparknotes Math IIC help at all?</p>
