<p>anyone remember what they got for the cone question? it asked about how deep it was and i had something do to with 1/2</p>
<p>If the answer for the matrix question was 5x4, does anyone know what letter answer that was?</p>
<p>I got 3.2 for that one.</p>
<p>Anyone think we’ll see a standard 44=< curve for do you think it’ll go down a bit to 43/42?</p>
<p>for the cliff on i got 21 because i think i did sin(45)=x/the distance that they gave us</p>
<p>what was the answer for the cone? i marked 2.00 but think that i’m wrong…</p>
<p>curve predictions? also pretty certain that 2.00 is correct</p>
<p>Oh man, I don’t know how I missed the range question… My head just wasn’t in the right place today.</p>
<p>i put 2 for the cone as well</p>
<p>and for the one that asked to identify the graph that had an inverse function? which one was it??</p>
<p>for the inverse it was A it was in quadrant 3 and 1 going up and it was like a curve kinda thing</p>
<p>For the cliff one i think i got 41 too</p>
<p>What was the distance between the 30 degree and 45 degree places for the cliff question?</p>
<p>@alexbcn A i think, you do the horizontal line test for inverses</p>
<p>inverse was the one that was one to one</p>
<p>It was the first graph that had a 1-1 function
what was the one about F(1.4) thing when F(x) = (x-1)F(x-1)
I totally shat on that problem and omitted it</p>
<p>perfect i also got A!
and the one witn the series:
a1=5 a2=9
the first number over 1000 was 1001,right?</p>
<p>Still not sold the answer to the cone is 2.00. I might have misread the question, but here’s my thinking. </p>
<p>Since the ratio of the height to the radius is 2:1 (we are given original height 4 and radius 2), the volume is 16pi/3. Now the volume of our new cone has to be 8pi/3, which is half of the original volume. The ratio of the new cone’s height to radius is also 2:1, so we can create a new equation: </p>
<p>(1/3)(pi)(r^2)(2r)=8pi/3</p>
<p>That eventually results in r^3=4, and the cube root of 4 is 1.6. However, it asks for the depth of the cone which is 2r so you multiply that by 2 to get 3.2</p>
<p>Yes, first number over 1000 is 1001. You just subtract 5 from all the answers and see which is the smallest one divisible by 4.</p>
<p>the F(X-1) whatever problem the answer was a- 1.08 i think</p>
<p>For the cliff i got 41 ft because the proportion of 1:root 3 (306090 and 45 triangle) is the same as 41:71(which accounts for the 30 ft decrease)</p>
<p>@Nuggers I got 3.2 too.</p>
