<p>what was the double absolute value question? was it none? and wat is the period one? and how bout hte p=n question. i got all odd</p>
<p>NspiredOne
the absolute value one was number of solutions to abs(3x-2)=-abs(x+21), which has no solution since left side is positive and right side is negative (well, technically, left is non-neg and right is non-pos, but since they can’t both be zero for the same value of x, it doesn’t matter)</p>
<p>can someone tell me the formula for the 500,000 reduces 18% in 20 years, i forgot it and i was mad about that</p>

<p>the equation for the longest diagonal of a recangular solid is</p>
<p>d=(l^2 + w^2 + h^2)^(1/2)</p>
<p>We’re given the diagonal of one face. The diagonal makes a right triangle with the diagonal as the hypotenuse, so (85^(1/2))^2= l^2 + w^2</p>
<p>substitute that into the first equation and the height is 3 so h=3…</p>
<p>d=((85^(1/2))^2 + 3^2)^(1/2)
d=(85+9)^(1/2)
d= root(94)=9.7</p>
<p>what was the equation with the equidistant?</p>
<p>^i did too, took way too much time imo to realize it because i was used to it being increasing, not decreasing.
1-.18= .82
500k * .82^20</p>
<p>What was the answer to the mean, median salary one? Spent a good two minutes pondering over it</p>
<p>UGH that population decreasing one screwed me over -____-</p>
<p>wait…are we allowed to discuss this?</p>
<p>i got the mean increases?</p>
<p>Ok great, that’s what I put.</p>
<p>Gahh I was going to put zero for the absolute graph one but I skipped it cause it seemed too easy!</p>
<p>Counting one with 5 letters (VWXYZ) followed by 5 numbers from set {0,1,2,3,…9}:
5! * 10!/5!</p>
<p>^answer choice C or D?</p>
<p>i put mean increases</p>
<p>okay what about the graph with the y intercept at 2 1/f(x)? i think it was a e^x function graph and the graph i picked was the graph that curved down?</p>
<p>ahua852
sorry: no idea if it was (C) or (D), but some of the other answer choices I think were something like:
5! * 10!/5
5!/4! * 10!/5!
5!-10!/5
5!+10!/5!</p>
<p>SatTooEasy-
I chose some random exponential function with a y-int of 2, say (2*(3^x)), graphed 1/that and I think I chose A. Not sure whether that’s what you mean by “curved down.”</p>
<p>Hiking-
Thanks, all I remember for that one is that I originally picked C then changed my mind to D. Don’t remember how/why.</p>
<p>sat too easy, i think thats what i put</p>
<p>SAT too easy i think that was A right? if you looked at the 0,0 part it shoudla been like 0,.5</p>
<p>I put A for the graph one</p>
<p>anyone remember which number the abs value one was?</p>
