<p>i graphed and got a period of 3…
isnt there another way to approach that kind of question tho?</p>

<p>For p^3q^6s^9 was that choice D? the one above the one that had a 243 exponent lol
for the period 3sin(pi x) + 2cos(2pi x) I graphed it and it repeated every 2 so I put 2… was A I think…
For the function tables I put II and III because I don’t think the first one was a function there were more than one x for each y</p>

<p>ANSWERS SO FAR: CAN ANYONE CONFIRM :slight_smile:
period = 2
5.7 million with 1.5% increase= 4 years
std. deviation = the choice with one bar</p>

<h1>of intersections @ x-axis = 2</h1>

<p>log n / log 2 problem= 19</p>

<p>it was a*sec </p>

<p>^
Which question was this for?</p>

<p>Oh and how many can you miss usually and still get an 800?</p>

<p>“For the function tables I put II and III because I don’t think the first one was a function there were more than one x for each y”</p>

<p>That would mean that x^2 is not a function.</p>

<p>logn/log2 I got 18.</p>

<p>And period i got 3.</p>

<p>For the functions one I put I, II, and III.</p>

<p>dannnnnnnnnnnnng
what was the polar coordinate answer? </p>

<p>2,3pi/2 </p>

<p>or something</p>

<p>■■■ stupid mistake… What do you guys think a 43 raw would be</p>

<p>you can skip upto 6 and get nothing wrong = 800</p>

<p>“For the function tables I put II and III because I don’t think the first one was a function there were more than one x for each y”
^</p>

<p>It’s still a function if there’s more x’s for each y…think parabolas.</p>

<p>I confirm all of cherryfilter’s answers.</p>

<p>Ya the polar one was 2,3pi/2 cause there was no point pointing south 2 units from origin</p>

<p>for log n /log 2 i put 19 because when you calculate it the answer comes out to be 18.1 but you have to find the LEAST interger thats GREATER than 18.1, which is 19.</p>

<p>yea i got 19</p>

<p>Oh what was the answer for the triangle ABC with side lengths 5,6,7 asking for the one of the angles?</p>

<p>the answers i remember putting are…</p>

<p>tan 120
10tan66 or something like that the one with flag pole stuff
x2+ y2 = 9</p>

<p>can anyone confirm?</p>

<p>i confirm 10tan66. I don’t remember tan 120 though. What was the question about?</p>

<p>For the standard deviation problem, can someone explain why the answer wasn’t the graph with all four bars of equal height?</p>

<p>tan 120
10tan66 or something like that the one with flag pole stuff
x2+ y2 = 9</p>

<p>can anyone confirm?</p>

<p>^ Those are all right.</p>

<p>x^2 + y^2 = 9 is correct.</p>
