June 2006 - Math Level I

<p>does anyone know about fileing a complaint....also what happens to all teh people that left 49 blank...will they mark it correct?</p>

<p>me too!...what will h appen if tehy make a mistake,,,i left it blank</p>

<p>Can u post the problem? I want to know it to try.</p>

<p>yea worth thats what i said</p>

<p>Question 49 asked given y=-3x+12 and another line I can't remember, what is the area of the triangle formed.</p>

<p>49 was the one where they gave you an equation and said "If f(3)=f(k), what is a possible value of k," right?</p>

<p>Because if so, that didn't have the answer. It had something CLOSE, but not right.</p>

<p>No, that I got A. Definitely, I was most certainly the right answer. No again, it's the coordinate geometry question with the lines and the area it's enclosed.</p>

<p>well if 49 is the question that asked about the two lines forming a triangle with the y axis then i think that one did have an answer, u find the point of intersection, the x value is the height, base was 9, use the triangle formula to find the area, im not 100% sure though about what i got</p>

<p>Was the base 9? If I'm correct, the base would be 5.5, not 9. Does anyone remember the two equations?</p>

<p>for number 49 with the two lines and the area of the triangle i got 8.1 as the area....
because u had to do...9(1.8)/2</p>

<p>im sure it was 9 cuz one had a y intercept of 12 and the other had a y intercept of 3</p>

<p>distance was 45 not 50
it was 3 to -8 then to 19 then down 7
11+ 27+7=45</p>

<p>the base was most certaintly 5.5, and i think the height was 6.6. however, 18.2 was not an answer. i think i put the closest one.</p>

<p>yeah i think thats wat i got too asparo, it sounds really familiar</p>

<p>no because the points of intersection of both lines were (0,3) and (0,12), so the base was 9</p>

<p>im 90% positive the answer to 49 was 8.1...anyway, does anyone remember the question with the sin squared and cos squared....i got 15 as an answer</p>

<p>I definitely remember doing what DH9800 did. Except, I left it blank. Equations anyone?</p>

<p>swatman 19-7 is 12 not 7, so its 11+27+12=50</p>

<p>yeah that sin^2+cos^2 was 15</p>

<p>those are y intercepts, we need the x intercepts.</p>
