In a rectangular form of a complex number, where a + bi, a and b equates to the location of the x and y respectively in a complex plane. The modulus |z| is the term used to describe the distance of a complex number from the origin. Hence, |z| = √(a²+b²)

Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.
Irrational numbers are "not closed" under addition, subtraction, multiplication or division. The numbers that are in the set of Complex Numbers, but are not in the set of Real Numbers .the imaginary number, i, which is the square root of negative one.
Distance of Foci = c
Then,
c = 4
As c^2 + b^2 = a^2
And, b = 3
Then us will have:
a^2 = 4^2 + 3^2
a^2 = 16 + 9
a^2 = 25
a = 5
The equation of ellipse to this question is:
x^2 / a^2 + y^2/b^2 = 1
Then,
x^2 / 25 + y^2 / 9 = 1
