<p>Damn, Alright then what was the answer to the question with the choices</p>
<p>-2i-1
2i+1
one more that i dont remember</p>
<p>-2-i</p>
<p>Only imaginary zeroes occur in conjugate pairs, so -2 + i and -2-i.</p>
<p>^ did’nt it have 3 to it?</p>
<p>At jamesford and diamondbacker. Thanks.</p>
<p>^no. it doesn’t have to have a 3</p>
<p>does anyone remember the question: sin(sinX)= 0.3 and you needed to find what cosx=? </p>
<p>also, I think i got 159.6 for the surface area of the triangular prism. anyone else?</p>
<p>I also got -4/7 for an answer. does anyone happen to remember what the question was for that/ did anyone else get that answer?</p>
<p>No, just because an equation has a root at one real number, it doesn’t HAVE to have a root at its opposite. </p>
<p>Graph the equation and you’ll see.</p>
<p>I got those, bluedaisy.</p>
<p>For sin(sin x) = 0.3</p>
<p>You have to take the arcsin of the arcsin of 0.3 to get x, then plug that into cos x.</p>
<p>The prism was 157 from what everyone else has said (I don’t remember it).</p>
<p>I remember seeing -4/7, don’t know if I put it or not.</p>
<p>I got a -4/7 somewhere</p>
<p>me too^ 10char</p>
<p>yeah i got taht too.</p>
<p>i vaguely remember questions like these as well:</p>
<p>f(x)= x(x+2)(x-2) / (x-2) and 2ln(x) / (x-1) </p>
<p>anyone remember anything about them?</p>
<p>1st one was which statement was true, talking about discontinuity.</p>
<p>the second one was finidng the limit at x=1? I don’t remember…</p>
<p>I got -4/7 also.</p>
<p>No, I was saying that the question had 3 as another 0 value</p>
<p>Can anyone write the question for the probability of the odd product one? I tihnk I can solve it now, but I didn’t have enough time to think about it during the exam…</p>
<p>does anyone remember the range problem anymore? the one where most of you got y > -.7 something? I think I got something else, just want to see how you guys did it.</p>
<p>for the discontinuity one the answer was x=1.</p>
<p>Discontinuity means you cancel x-1 or sumthin out of both the numerator and denominator.</p>
<p>Am I right?</p>
<p>@ Walton:</p>
<p>What is the probability that a random number (M) is selected from the numbers 1-10, inclusively, and another number (N) is selected at random from another set of numbers, 1-20 inclusively will have the product of MN as an odd number?</p>
<p>Answer choices were: like 1/4, 1/2 or some others.</p>
<p>Sorry the wording to the question is a little funky.</p>
<p>^ Answer is 1/4, dammit. Wasn’t that proved earlier?</p>
<p>yay i guessed with 1/4 and i got it right!</p>
