Answer:
Step-by-step explanation:
We can determine the power of a complex number by the De Moivre's Theorem, which states that for all 
, where 
, the power of the complex number is:
(1)
Where:
- Magnitude of the complex number, dimensionless.
- Direction of the complex number.
If we know that 
, 
and 
, then the fourth power of the complex number is:
![z^{4} = 1^{4}\cdot \left[\cos\left(\frac{8\pi}{3} \right)+i\,\sin\left(\frac{8\pi}{3}\right)\right]](https://tex.z-dn.net/?f=z%5E%7B4%7D%20%3D%201%5E%7B4%7D%5Ccdot%20%5Cleft%5B%5Ccos%5Cleft%28%5Cfrac%7B8%5Cpi%7D%7B3%7D%20%5Cright%29%2Bi%5C%2C%5Csin%5Cleft%28%5Cfrac%7B8%5Cpi%7D%7B3%7D%5Cright%29%5Cright%5D)
The answer to the question is ORTHOCENTER. The altitude is the line that connects the vertex of a triangle to the opposite side making a 90 degrees with it. Thus, the use of the prefix ortho- for the points where the three altitudes meet.
Answer:
The operations you see with you eyes are multiplication and addition.
4 times X plus 2 = 10
The operations you don't see are Subtraction and Division.
4x+2=10
Subtract 2 from both sides.
4x+2−2=10−2
4x=8
Divide both sides by 4.
4x/4 = 8/4
x=2
You would half to take 8×(8×pi r squared)
1 month 29 days but if the month have 29 days each then the it will be 2 months
