September ACT Math Discussion

<p>I thought I would make one since I didn't see one. :)</p>

<p>for #59, the question asked how is the domain of -x^5 different than f(-x^5), the answer was E, they were both the same domains right?</p>

<p>That’s what I put :)</p>

<p>for the question about the square and they take away a 3x4 rectangle and ask which of the remaining shape had the greatest perimeter, the answer was A right?</p>

<p>Okay, one last question…#1, the answer was like 80x+60y and not 320x+60y right?</p>

<p>I think so (remember it was a beginning answer)…cause it had two side lengths of four and one three taken out…others had 2 three lengths taken out and one four.</p>

<p>Other choices were obviously not right :)</p>

<p>yep, that’s right :)</p>

<p>I hate this 60 second rule :'(</p>

<p>I had two questions: </p>

<p>First was the one where a, c, and b were constants and x and y were variables and they asked to solve y. </p>

<p>Second question was the property that the club bought and would put a flag in the middle and ground lights around the circle. They asked what was the angle and I wasn’t sure - i think I put 30 degrees.</p>

<p>It was 60 for the angle, equilateral triangle.</p>

<p>1) use elimination method to cross out the A’s then you add them up and isolate Y…remember the answer was towards the end of the choices.</p>

<p>2) It was an equalateral triangle, so 60 degrees I believe</p>

<p>it was 60 degrees cuz it was an equilateral triangle, the distance between the two flagpoles was the same as the radius so you figured it out like that</p>

<p>For the one with graphing inequalities, I think I remembered which way to shade, but not 100%.</p>

<p>Was the answer A? :o</p>

<p>The question that asked how long was the distance between the two girls’ houses it was like 6.4 or something rounded down to 6 right?</p>

<p>@mathisfun111: I believe so, because that’s what I put</p>

<p>@allenl513: Yes, it is 6.</p>

<p>For the question asking about the product of prime numbers, is it 210? (2x3x5x7)?</p>

<p>i got 6 :)</p>

<p>and yes it was 210 :)</p>

<p>For that one of the intersecting graphs g(x) and f(x) what was the answer?</p>

<p>I don’t really remember the question, but I think that I just guessed -2.</p>

<p>@fdgjfg wasn’t it just 2? not negative 2</p>

<p>@ckpckp1994 210 is correct!</p>

<p>I don’t remeber the answer exactly…but it may be 2 since the x coordinate was (2,1) or something like that.</p>

<p>You just looked where the graphs intersected :)</p>
