Answer:
After solving the power:
Rectangular form:
Step-by-step explanation:
Given the complex number:
To find:
The indicated power by using De Moivre's theorem.
The complex number in rectangular form.
Rectangular form of a complex number is given as 
where a and b are real numbers.
Solution:
First of all, let us have a look at the De Moivre's theorem:
First of all, let us solve:
Let us apply the De Moivre's Theorem:
Here, n = 3
Now, the given complex number becomes:
Let us put the values of 
and 
So, the rectangular form of the given complex number is:
Answer: A. $3.30
If you divide 6.60 by 2 you get 3.30
If you divide 9.90 by 3 you get 3.30
If you divide 13.20 by 4 you also get 3.30
Answer:
y= 2/3 x
Step-by-step explanation:
First plot the points on a Cartesian plan
You will notice a straight line passing through the origin (0,0)
Find the gradient of the line;
m=change in y/change in x
m=2-0/3-0 =2/3
Find the equation of the line
y-2/x-3 =2/3
3(y-2) = 2(x-3)
3y-6= 2x-6
3y=2x-6+6
3y=2x
y=2/3 x + 0
Always
Because the slant length is the longest length when looking at the Pythagoras theorm
In this case the slant is y, with x and y as the height and base
y²=
Hence y the slant is the sum of the height and and base and will always be larger
Isnt it less ? Correct me if im wrong
