Answer:
Y=50x + 200
Step-by-step explanation:
For every month, which is represented by X, the overall price, represented by y, goes up by 50 so we must multiply 50 by the number of months on the plan, X. We also have to factor in the one-time cost of the phone plan itself, which is 200 and ALSO does not go up with every month, so we add 200 to the equation of 50x, giving us 50x + 200, all we have to do from here is show what this equation is doing, which is giving us the answer to Y (the overall price of the plan), and we finish with Y=50x + 200
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:

6.05 x 10^5
I think this is the answer
50 times 30 is 1500 and 9 times 8 is 72 added is 1572
