it equals <span>(−<span>12</span>)</span> because <span><span>cos<span>(<span>60∘</span>)</span></span>=<span>12</span></span>
Explanation:
The reference angle for <span>240∘</span> is <span>60∘</span> (since <span><span>240∘</span>=<span>180∘</span>+<span>60∘</span></span>)
<span>60∘</span> is an angle of one of the standard triangles with
<span><span>cos<span>(<span>60∘</span>)</span></span>=<span>12</span></span>
<span>240∘</span> is in the 3rd quadrant so (either by CAST or noting that the "x-side" of the associate triangle is negative)
<span><span>cos<span>(<span>240∘</span>)</span></span>=−<span>cos<span>(<span>60∘</span>)</span></span></span>
<span><span>cos<span>(<span>240∘</span>)</span></span>=−<span><span>12</span></span></span>
Hello!
It tells you what to do in the question
First round all the numbers to the nearest whole number
2.20 = 2
2.34 = 2
2.7 = 3
Then it says to multiply all the numbers
2 * 2 * 3 = 12
Then it says to divide by 6
12 / 6 = 2
The answer is 2 cubic yards
Hope this helps!
Independent variable (IV): something the scientist can change.
Thus, in this case, the IV can be the weight of the person.
