Official June Math IC Discussion!!!!

<p>well, discuss.</p>

<p>What was the answer to the one where you have to divide polynomials? I remember it was in the middle somewhere, and (X-1) was one of the answer choices.</p>

<p>i think i did the one with 2 in it</p>

<p>what was the answer to the one with a doesn't = b, (a^4)(b^3) = (ab)^3?</p>

<p>What was the one with a triangle with one side as a diameter inscribed inside a circle, and they ask how many such triangles are possible not including the one they already drawn?</p>

<p>This was the only question that I wasn't 100% sure of</p>

<p>I put 3 after thinking for some time.</p>

<p>"what was the answer to the one with a doesn't = b, (a^4)(b^3) = (ab)^3?"</p>

<p>was there an answer choice that said a=1? If so, then that's what I put. if not, tell me what the answer choices were again.</p>

<p>did anybody else feel like there were a million distance equation problems? I thought that was utterly beautiful because my homemade distance eq TI-83 program saved me loads of time on IC.</p>

<p>i >think< the choices were: a =1, b=1, ab>0, b>0, and i forget the other one.</p>

<p>"What was the one with a triangle with one side as a diameter inscribed inside a circle, and they ask how many such triangles are possible not including the one they already drawn?"</p>

<p>For that one I took a big risk and put infinite number, because I couldn't remember if it said if you could rotate the diameter... but I guess I shouldn't even have bothered with posting since I'm no help. lol. sorry.</p>

<p>I would help, but I didn't have enough time to answer that question.</p>

<p>It's not infinite</p>

<p>Because I tried creating triangles with 45-45-90 angles and antoher with 30-60-90and made up my own radius and the triangles don't have the same area, so its not infinite. Also, you cant rotate the diameter</p>

<p>I narrowed it down to 3 or 4. I put 2 but I'm just worried that there might be an extra one I missed.</p>

<p>it was infinite...because if you keep the diameter, and move the other point anywhere on the circile, it will give you the same area. This test was soooooooooo easy. I hope i made a LEAST an 800... well, i say this because i took the math IIC as well...good luck guys:)</p>

<p>Apollo, try drawing triangles to see</p>

<p>First we that that all the triangle we make will be right triangles since one of the angles will always be 90.</p>

<p>Try making a 30-60-90 triangle and a 45-45-90 triangle, using 4 as the diameter. You get different areas, which contradicts that one can make infinite triangles of the same area</p>

<p>They didnt say ALL of the ones drawn must be 90 degree triangles. Just the examples given were right triangles.</p>

<p>They must all be 90degrees </p>

<p>Why? Bececause since the diameter is a side, the angle opposite it is an inscribed angle of 90degrees always. </p>

<p>So I don't think the answer is infinite.</p>

<p>Anyone get 5 for the one with the quarter circle and the 90 rotation one what was that? f(x+1)=3x2+6x+3 what is f(x) i had 3x+3</p>

<p>f(x) is 3x^2</p>

<p>To get this, factor f(x+1) first and then you'll see</p>

<p>What did you get for the quarter circle one? and i dont' see the 3x2 i forgot how to do it i just went (x+1)(3x+3)=3x2+6x+3 Post any others that were kinda difficult</p>

<p>3x2+6x+3 factors into 3(x+1)^2 . you only factored partially. take out the 3 in the (3x+3) .</p>

<p>I don't remember the quarter circle question. What is it? Most of the questions were very straightforward, so I'm not sure how to answer your last question.</p>

<p>It had a triangle with a side length of 5 and 30 degrees in the bottom and there was a quarter circle overlapping it. You had to find AD of the triangle ABC and D was between A and D.</p>
