Answer:
18
Step-by-step explanation:
√25+13= 5+13=18
Multiply the diameter by PI which is 3.14 so that means the circumference would be 15.7.
Answer:
-7π/3 or -420 degrees
Step-by-step explanation:
So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.
The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.
π/2 - π/6
3π/6 - π/6 = 2π/6
π/3
Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3
Answer:
6
Step-by-step explanation:
all sides of a square are equal
Answer:
The complex number notation of 12-sqrt(-8) is 12 - 2.828i
Step-by-step explanation:
Given:
12-sqrt(-8)
To Find:
The complex number notation of 12-sqrt(-8)
Solution:
12-sqrt(-8) can be 
where 
can be written as
Now using the below radical rule which states that
Then,
=> 
=> 
-----------------(1)
Also we know that
---------------------(2)
substituting (2) in (1)
we get
=> 
=> 
=> 
=> 2.828i
