<span>A. cos(x) = cos(-x) [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph. [false]
C. cos(x) = -cos(x) [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin. [false]</span>
Interest on first loan = 800*.075*2 = 120
<span>so the interest on the second loan </span>
<span>= 138-120 = 18 </span>
<span>using the simple interest formula: </span>
<span>18 = P*.03*2 </span>
<span>P = $300</span>
Height to arm length ratio: 6:3 ft or 2:1 (since 36 inches is 3 feet)
If you were 30 feet tall, your arm would be 15 feet long.
I think is the answer because the right side =0 and so basically your left with the left side. 6(x² - 1)
It can lie between any number lower than it and any number high than it.
For example, 419 and 421
