Answer:
x ≥ 6 or x ≤ -2
Step-by-step explanation:
- I x - 2 I + 4 ≤ 0
- I x - 2 I ≤ -4
I x - 2 I ≥ 4
x - 2 ≥ 4 or x - 2 ≤ -4
x ≥ 6 or x ≤ -2
The graph looks like this, on the enclosed pic:
One feature is that it's periodic and torn (has cut-off points), meaning the domain is the same as in case of tan(x): x€R and x =/= π/2+πn.
The range equals the range of arcsin(x): -π/2<=y<=π/2 OR y€[-π/2;π/2]
Hope could understand and if it helped! :)
Answer: 61.92751306414704
Step-by-step explanation:
From this picture you can calculate coordinates of triangles' vertices:
![A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)](https://tex.z-dn.net/?f=A%28-9%2C0%29%2C%5C%20B%28-6%2C-4%29%2C%5C%20C%28-3%2C0%29%2C%5C%20J%288%2C0%29%2C%5C%20G%285%2C4%29%2C%5C%20H%282%2C0%29%20)
.
Since
you can conclude that points A, B, C are rotated by
![180^0](https://tex.z-dn.net/?f=180%5E0)
about the point (-0.5,0) to form points J, G, H, respectively.
Answer: A is correct choice.
A quartile is a type of quantile. The first quartile (Q1) is defined as the middle number between the smallest number and themedian of the data set. The second quartile (Q2) is themedian of the data. The third quartile (Q3) is the middle valuebetween the median and the highest value of the data set.
