Answer:
542
Step-by-step explanation:
So X is the number of finals graded by teacher last year
she graded 83 more finals than the last year
and the total number of finals she graded this year is 625 so we have an equation
X + 83 = 625
and as you solve it for X
X = 625-83
x = 542
Answer:
B
Step-by-step explanation:
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:
The sum (addition) of t and 2 is equal to (=) 5 less than (subtraction) t
2 + t = t - 5
