April 2011 ACT Math Discussion

<p>-sigh- I thought the math was the hardest…</p>

<p>Well I’m off to eat. Later people and goodluck on our scores!</p>

<p>I think we’ve established it was I & II for that problem, thought I still don’t have any idea what the set of domains for P(x,y) means.</p>

<p>i put 4 for that one, it was like reading chinese … i just took the two biggest x and y values that would give me the biggest product, i had no clue</p>

<p>We get our tests back! yaaay :D</p>

<p>^What? o.O</p>

<p>mathisfun111, want to elaborate?</p>

<p>Can someone tell me what the Jamal answer was. The fact that the person was named Jamal kept distracting me to the point where I couldn’t solve the problem at all.</p>

<p>What was the answer to the question that asked the maximum value of P(x,y) given that it adhered to the inequalities? I got 4 because I thought it was the greatest combination…</p>

<p>@Nicolascage
wasnt it 16? Or am i thinking of the wrong question…</p>

<p>On the question about what shape it would make if you cut the cone down the middle, the correct answer was the one with the curved bottom. I was worried because everyone said they picked the one with the flat bottom, so I just cut a funnel in half. The result was a triangle with a curved bottom.</p>

<p>wait, i thought i got that wrong about the coned triangle?</p>

<p>@laptop1 What answer letter was 16? I completely guessed on that one and I’m hoping I got lucky…</p>

<p>I don’t know I thought that I got it wrong because I said the curved bottom, but my mom gave me an old funnel to cut in half and when we spread out one of the halves it had a curved bottom!</p>

<p>What was the questions where the answer was 44? It sounds familiar but I don’t remember the question.</p>

<p>Hm, i cant remember the exact letter…sorry :/</p>

<p>ah alright that’s okay</p>

<p>Cutting a cone in half produces a cross-section with a triangle face. Depending on the perspective, it could look like it has a curved bottom, but I assume the question was if you were looking directly at it, not if you were looking below it. If you just think about it, a cone has a flat bottom. If the cross-section had a curved bottom, the cone would have to have a curved bottom as well, which it doesn’t.</p>

<p>Jamal problem: the answer was 47.</p>

<p>As for the cone, it’s definitely a triangle.</p>

<p>Take an icecream cone- the perfect cone shaped one. Turn it upside down, and set it on a table. See how it stands? Yeah, thats because it has a flat base. If it had a curved base- it wouldn’t sit. If you slice a perfect cone in half, you get a triangle.</p>

<p>A cone can’t ever have a curved bottom. A right cone (as on the test), would be able to sit on a table. How can a cone with a curved bottom sit on a table? Turn an empty ice-cream cone upside down and try to stand it on the table – it works because it’s flat, not curved.</p>

<p>The answer was the triangle with all straight sides.</p>

<p>Edit: @sbl wow, we both referenced the same site within seconds of posting… lol</p>

<p>Can someone elaborate on how he got 16 on the P(x,y) problem. There goes my shot at 36 X(</p>
