<p>f(x) = [1/(2a)]^x</p>
<p>f(2x) = [1/(2a]^(2x)
Substitute x for 2x</p>
<p>f(x)^2 = ([1/(2a)]^x)^2 = [1/(2a)]^2x
Simply, a power to a power is the multiplication of the powers</p>
<p>f(2x) = f(x)^2 = [1/(2a)]^2x</p>
<p>Answer: [f(x)]^2</p>
<p>@Brolex… what was the question asking? Was it asking for surface area?</p>
<p>@FlamingMango</p>
<p>That is beautiful.</p>
<p>jd989898 I did</p>
<p>do you remember the other choices flamingmango? this one has me worried, i have no idea what i put D:</p>
<p>I remember .5f(x) and 4f(x).</p>
<p>**1/2[f(x)]</p>
<p>sqrt[f(x)]</p>
<p>4[f(x)]</p>
<p>[f(x)]^2 **</p>
<p>Thats what i remember</p>
<p>alrighty, well i guess that ones up in the air for me. right now im at -3 for sure, -4 maybe.</p>
<p>i just hope its an improvement from my 640, im kinda thinking it will be so far, so all i can do is keep my fingers crossed :P</p>
<p>was the sequence question 1?</p>
<p>it was 1024 ^</p>
<p>Instead of 5/2 I wrote 10/4. Am i screwed?</p>
<p>I believe the answer to the sequence question was A, which is 32^2.</p>
<p>I’m at -4 for sure. I had an experimental section. </p>
<p>I’m thinking 720 or lower… Praying to god that the ones I missed were in experimental, so I would have a 740-760.</p>
<p>Seriously though, can anyone tell me what the cylinder question was asking? Was it asking for surface area?</p>
<p>The answer I got was (f(x))^2</p>
<p>The cylinder was surface area</p>
<p>Surface area of the cylinder, given that its ends are open. Diameter 8, height 20.</p>
<p>you are allowed to write it as 10/4 :)</p>
<p>The answer was like 500 for the cylinder one</p>
<p>Seriously…They said the ends were open…Can anyone corroborate this claim? If this is so, I will probably cancel.</p>
<p>the ends were open dude</p>
