1. According to the plots, the curves intersect when and .
We can confirm this algebraically.
(where is an integer)
We get the two solutions we found in the interval [0°, 360°] with in the first case, and in the second case.
2. We have when . For the given plot domain [0°, 360°], this happens when .
3. The domain for both equations is all real numbers in general, but considering the given plot, you could argue the domains would be [0°, 360°].
is bounded between -1 and 1, so is bounded between -1 + 2 = 1 and 1 + 2 = 3, and its range is [1, 3].
Likewise, is bounded between -1 and 1, so that is bounded between -1 + 3 = 2 and 1 + 3 = 4, so its range would be [2, 4].
The correct answer for the question that is being presented above is this one: "B. 68%." The weights of a bat in a zoo are normally distributed with a mean of 2.2 pounds and a standard deviation of 0.3 pounds. The percent of the bats at the zoo that weigh 1.9 pound and 2.5 pounds is <span>B. 68%</span>

Answer: -4</h3>
==========================================================
Explanation:
We can pick any two rows from the table to get the (x,y) points needed to find the slope.
Let's say we pick the second and third rows
Subtract the y values: 14-6 = 8
Subtract the x values in the same order: 1-3 = -2
Divide the differences: 8/(-2) = -4
The slope is -4
--------------------------------------------------
You can use the slope formula
Let's say the points are (x1,y1) = (1,14) and (3,6)
m = (y2-y1)/(x2-x1)
m = (6-14)/(3-1)
m = -8/2
m = -4
It's the same basic idea as the previous section. You subtract the y values together (y2-y1) and the x values together (x2-x1) and divide the differences to get m. The order of subtraction doesn't matter as long as you stay consistent. If you do something like y2-y1 and x1-x2, then you'll get the wrong slope value.
