Answer: B
Step-by-step explanation: The question is asking for the point greatly different from all the rest, the outlier. Point B is far away from the grouping of all the other points, making it the outlier.
Answer:
B) ![y=sin(x+\frac{\pi}{2})](https://tex.z-dn.net/?f=y%3Dsin%28x%2B%5Cfrac%7B%5Cpi%7D%7B2%7D%29)
Step-by-step explanation:
Technically, since the function starts at its maximum, you could say the function is
, but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity
and we can see that the correct answer is B.

Answer:
a. ![\frac{x + 3}{21}=\frac{x + 1}{15}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20%2B%203%7D%7B21%7D%3D%5Cfrac%7Bx%20%2B%201%7D%7B15%7D)
b. x = 4 (see steps below)
Step-by-step explanation:
Since the two polygons are similar, the sides are proportional to each other. Using a proportion, you can solve for 'x' using cross-multiplication and division:
![\frac{smaller}{larger}=\frac{x + 3}{21}=\frac{x + 1}{15}](https://tex.z-dn.net/?f=%5Cfrac%7Bsmaller%7D%7Blarger%7D%3D%5Cfrac%7Bx%20%2B%203%7D%7B21%7D%3D%5Cfrac%7Bx%20%2B%201%7D%7B15%7D)
Cross-multiply: 15(x + 3) = 21(x + 1)
Distribute: 15x + 45 = 21x + 21
Subtract '15x' from both sides: 15x + 45 - 15x = 21x + 21 - 15x or 45 = 6x + 21
Subtract '21' from both sides: 45 - 21 = 6x + 21 - 21 or 24 = 6x
Divide by 6 on both sides: 24/6 = 6x/6
Solve for x: x = 4
