<p>SUPERNINJA!! yes you are correct on #54 being K… i had very similar reasoning, where you must select two polynomials within their limits of n<m or whatever it was, but the trick is in order to maximize the number of terms in the result when multiplied together you must have a result that does not simplify further than when you FOIL it!!</p>

<p>basically every term across both polynomials has to have a distinct power. that way every resulting term after multiplying will have a distinct power and nothing will simplify with addition and subtraction later. refer to superninjas posts for examples :)</p>

<p>on another note, did anyone find the reading hard? i have gotten two 35 composites, one with a 36 on reading and i didnt even finish the last passage :(</p>

<p>and any for sure answer on the bags of mulch one? i didnt catch the bags filled different depth than he wanted…</p>

<p>On the question with the graph that was x+3/x^2-4 it asked what the value of x couldn’t be and I think I put -2. Is that right?</p>

<p>-16 i think, since it was -11 minus 5</p>

<p>-2 was an asymptote so yes</p>

<p>i think it was .16</p>

<p>It said “constant speed”, so wouldn’t the graph be linear? sine graphs kind of show an exponential rate of decline and rise</p>

<p>bags of mulch was 17… i thought the middle two passages were more difficult than usual. i thought that prose was much easier than usual. It is usually my downfall</p>

<p>does anyone know i think #57 with the 10 inch chord and i think 14 diameter?</p>

<p>i guess on that and put 5 but people say it was 4squareroot 2</p>

<p>Anyone know the answer to the ven diagram one? It was question 19 (an early one). I think it asked the percent or number of kids only in one honors class?</p>

<p>For the one honors class I put 50%</p>

<p>Me,too! Did you just add the ones that weren’t in the shared parts, if you know what I mean?</p>

<p>Yeah that’s all you do, but make sure not to add the ones that aren’t in any.</p>

<p>Ok good 50% is what I got too!</p>

<p>How do you solve the mulch one? 2 inches deep will cover 12 ft, and he wants it 3 in deep? Or something like that</p>

<p>@imparanoid if 2 inches is 12 ft, that means 3 inches deep only covers the top of 8 square feet. (both must multiply to equal 24). Then find the area of the triangle and divide by 8. I think the answer was like 54.5 rounded to 55 but i can’t remember.</p>

<p>What was the one with the graph of the inequalities where they all jumped down one- highest y value was at 5 there were like five of them? in 40’s/50’s…</p>

<p>i believe it was the one that had all of the lines contained</p>

<p>what do you think the curve will be?!</p>

<p>What was the answer to the set problem? The answer choices were like {0,1,2,3} or something?</p>
