<p>i dont remember lol, but if thats the case then you are right.</p>
<p>how bout the question 2^k, n * 2^K and 2^k+4 or something, like that does any1 remember how that question goes?</p>
<p>2^k is one point. 2^k+4 is another point. n2^k = midpoint of those two points. To solve it I just plugged in 1 for k. 2^1 = 2. 2^5 = 32. Midpoint = 17. So 17 = n2. n=17/2</p>
<p>you just put k in for a real number so like substitue all k's for 1 or 2 or 3 and you should get 8.5 if im not mistaken with any number you choose i substituted 1 2 3 and 1000 to make sure =] </p>
<p>17/2=8.5</p>
<p>unless that was an answer for a different question but thats how i attacked the question</p>
<p>alright good i thought the elevator was 3. its been hours so i cant remember. on the trapezoid, i can say that the base was 8 and that 20 and 24 were choices as perimeter. I know two circles were tangent, third tangent to each diameter, but thats it.</p>
<p>BTW the last one was definetly 34, i am 100 percent sure of that.</p>
<p>wait mtf612 do u know what order the choices are for the trapezoid?</p>
<p>The trapezoid is 20. Stop asking imo it's already been discussed =]</p>
<p>I got |x+32|>2 for that one problem about tire inflation. Why is this wrong??</p>
<p>No , I know two had roots, one was 20 and one was 24. </p>
<p>I know why alot of people say its 20, but it can also be 24 if a certain part is true. I got 20 at first, and 10 seconds later was all holy S*** and went back to it, messed around real quick and got 24. Its late and i need help remembering lol.</p>
<p>because if you put 35 for x then the answer would be true but the answer has to be between 30 and 34 and 35 is too large</p>
<p>llpitch, i dont think the problem worded them as points, do you remember the exact wording, or what exactly it asked for you to solve?</p>
<p>Tire inflation was definetly |x-32|>2</p>
<p>If you put 33.9 in you get |1.9| , and if you put 30.1 in you get |-1.9| . If you add you can put 5 pounds in and it will work. Needed to be 30 - 34 exclusive (no 30 or 34 allowed)</p>
<p>thanks mtf612 only if someone knew the order for the question ahha</p>
<p>Could someone kindly explain how to do the midpoint problem with the powers? I don't quite remember what exactly the problem was, but apparently the answer was 17/2.</p>
<p>I just explained how to do the midpoint problem...go to page 47.</p>

<p>I don't understand your logic (I also don't remember the exact problem). 1.9 is not greater than 2...</p>
<p>ok i remember it now. it was 2^k, n*2^k+1, and 2^k+4</p>
<p>if u plug in anything for K, then n=4</p>
<p>Oops sorry meant |x-32|<2
lol hope i didnt do that for real hahaha</p>
<p>n was 17/2.....see page 47 and my explanation.</p>
<p>but the midpoint was n<em>2^k+1 not n</em>2^k im pretty certain.</p>
<p>You're not correct. The midpoint was n*2^k.</p>
<p>Oops sorry meant |x-32|<2
lol hope i didnt do that for real hahaha</p>
<p>I still don't understand. Does someone know the exact problem? Could x only be between 34 and 30?</p>
