<p>What was the answer for that one? I had the general gist but had to make an educated guess</p>
<p>12 + 40 - 40 cos (alpha)</p>
<p>12+40-40cos(alpha)</p>
<p>try to look through the other discussion threads before makingccccccccccccccccccccccc new ones ^_^</p>
<p>The consensus is that it was 12+40-40 Cos (alpha). Only one that seemed logical.</p>
<p>Just assume angle is 90 degrees guys…then its horizontal, so the height must be radius+12.</p>
<p>does anyone remember what letter they put?</p>
<p>Agreed.</p>
<p>I just plugged in 90 for the angle and saw which one gave 52 (40 + 12), and then plugged in 180 for the angle and saw which one gave 92.</p>
<p>Answer was C or D.</p>
<p>C I think.</p>
<p>12 + 40 - 40 cos (alpha) was D.</p>
<p>Does anyone know if the last two choices (one of those were correct) if they both had 12+40 or if one of those choices had 12-40 because i know i put the one with 12+40 but i cant remember if i put sin or cosine!</p>
<p>for the matrices you just add to the same position of the other right?? for example
(5,6) (5,1)</p>
<h1>(1,2) + (6,2) that wasnt the exact setup but would the answer be </h1>
<p>(10,7)
(7,4)</p>
<p>@jka yes remember on the first few problems everything IS as easy as it seems (which tricks people out a lot :P)</p>
<p>ya just making sure lol, i think the reading and science are gonna have really generous curves</p>
<p>Aren’t we theoretically not supposed to even be talking about these questions?</p>
<p>@Salve: What questions?</p>
<p>Yeah, I used the process of elimination in addition to an educated guess, I am lucky i got that one right!</p>
<p>Exactly, I don’t know what these people are talking about…</p>
<p>does anyone remember that english question in the first part that had either a that, who, or whom answer?</p>
<p>i put that but i wasnt fur sure</p>
<p>if I remember the one your talking about correctly it’s that because it was referring to a thing not a person</p>
