<p>actually i think it was. the radius was 4, and the height was 10.</p>

<p>Arithmetic sequence: a1=7.</p>

<p>the diagram showed the cone with a height of 10, or am i mistaken?
and now that i remember, i put 7 for the arith. seq. because it differed by 4</p>

<p>

Yes. D was 8.</p>

<p>yeah thats what i got, 8</p>

<p>Can someone please tell me how polars work? There was a question I left blank on the test because I didn't know them. I didn't think they would be on the test... >.<</p>

<p>i thought 10 was the slant height of the cone??</p>

<p>yeah 10 was the slant height i believe</p>

<p>yeah i left that rcos(theta) one blank. so -2 omit 2 so far</p>

<p>10 was the slant height guys</p>

<p>oh, right. 10 was the hypotenuse of the triangle that you had to use to find the height.</p>

<p>so what was the height? and what answer did you put instead of D. 8</p>

<p>i think it still came out to be D right</p>

It's okay to discuss the questions here (against the copied statement though), but can we post them?
Well, it's time to redeem myself.
The question was "how many triangles?"
6 sin(42) = 4.01. Two triangles.</p>

<p>I did soo bad, 600 probably.</p>

<p>what was the arithmetic sequence problem exactly ?? was a3 = 15 ?? and whats a5 ?</p>

<p>a5 = 23 i think
a4 = 19
a3 = 15
a2 = 11
a1 = 7</p>

<p>I tried law of sine gcf101 and there were none</p>

<p>no, it was a3 is 15, a5 is 23. what is a1. answer = 7.</p>
