Answer:
none, it's not symmetrical in any way
Step-by-step explanation:
what I am supposed to write here
Answer:
It is true, because the cosine function has a period of 2π
Step-by-step explanation:
Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:
![Cos(\theta)=Cos(2\pi +\theta)](https://tex.z-dn.net/?f=Cos%28%5Ctheta%29%3DCos%282%5Cpi%20%2B%5Ctheta%29)
Taking
as
,
is equal to ![2\pi + (-\frac{\pi}{2})\\=2\pi - \frac{\pi}{2}\\=\frac{4\pi-\pi}{2}\\=\frac{3\pi}{2}](https://tex.z-dn.net/?f=2%5Cpi%20%2B%20%28-%5Cfrac%7B%5Cpi%7D%7B2%7D%29%5C%5C%3D2%5Cpi%20-%20%5Cfrac%7B%5Cpi%7D%7B2%7D%5C%5C%3D%5Cfrac%7B4%5Cpi-%5Cpi%7D%7B2%7D%5C%5C%3D%5Cfrac%7B3%5Cpi%7D%7B2%7D)
The equation is true!
<u>Note:</u> The cos function is even function
Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
So because B is midpoint then just you need divide 23,8 by 2 and will get AB ok
23,8/2 = 11,9 right
Answer:
x= 13/2
Step-by-step explanation:
multiply 4x4+4x3-9x2-x+2=x-1
calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13
solution x=13/2
Answer:
C
Step-by-step explanation:
These pairs are both interior angles and are consecutive because they are divided by a transversal.
