ACT April 4 ---- main discussion

<p>so what is it?? and what about the snowfall being reduced and expenses going up</p>

<p>guess its 1:1</p>

<p>hey, what did everyone get for the area of the rectangle one??? (the one with the parabola?) and also the sin graph... wat did everyone put??? (I put 2 but i think that's wrong)</p>

<p>i put e on the sin one...144sin72....and i put 32 feet on the height of the wall</p>

<p>It was that expenses would go up Galib.</p>

<p>What was the answer to the bcd abcd (with exponents) pattern question?</p>

<p>Thank you lol</p>

<p>I haven't taken trig. so those questions were impossible... What was that one that asked what the limit or whatever of the sin graph was? I think that's the one you're talking about killer.</p>

<p>Tilgaham don't remember the answer but you multiply by ac each time.... so i think like a^3bc^4d? i think?</p>

<p>The one asking about the period of the sine graph should have been pi because a regular period is 2pi and the graph was half a regular one.</p>

<p>Yeah that was it tim.... i just blanked out..... didn't know ANYTHING.</p>

<p>it was which ever one came out to equal 648...because i made a =1 b=2 c=3 and d=4....fisrt came out to 24...then72...then...216...obviously it was getting multiplied by 3...so forth one was whatever ='ed 648.</p>

<p>aww... no 36 on math =S what about the area of rectangle??? i think i put A</p>

<p>For the area of the rectangle under the parabola, I put the first answer choice. I ended up multiplying two things, don't really remember what</p>

<p>answer to those two questions:
1)a^3bc^4d
2) pi (not 2pi)</p>

<p>dang i think i put 1/2pi</p>

<p>yes david it was a^3bc^3d</p>

<p>the answer was a^3bc^4d
the key is that it was a geometric, not arithmetic sequence</p>

<p>what was the on in the science passage about somthing / (heptane+something) x 100 = something...</p>

<p>Anyone??? area and parabola?</p>

<p>isotane/(isotane + heptane) x 100</p>
