Answer: B.
Step-by-step explanation:
i just took the assignment
This can be expanded through the tangent angle addition formula:
tan(α+β)=tanα+tanβ1−tan -α + tanβ
Thus,tan(x+y)=tanx+tany1−tan x tany
Hope it helps you
I would go with A. while it's true that the function continues to increase the function only begins to increase when it's greater then or equal to -8.
The circumference of the smaller circle is ![[\frac{2\pi}{3} ]x \ units](https://tex.z-dn.net/?f=%5B%5Cfrac%7B2%5Cpi%7D%7B3%7D%20%5Dx%20%5C%20units)
.
The given parameters:
- Radius of the larger circle = x
- Radius of the smaller circle = ¹/₃ x
The circumference of the smaller circle is calculated as follows;
![C = 2\pi r\\\\C = 2\pi (\frac{x}{3} )\\\\C = [\frac{2\pi}{3} ]x \ units](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r%5C%5C%5C%5CC%20%3D%202%5Cpi%20%28%5Cfrac%7Bx%7D%7B3%7D%20%29%5C%5C%5C%5CC%20%3D%20%5B%5Cfrac%7B2%5Cpi%7D%7B3%7D%20%5Dx%20%5C%20units)
Thus, the circumference of the smaller circle is .
