The graph which correctly shows the point A as the sum of the complex numbers z₁ and z₂ is graph number 4.
<h3>What is complex number?</h3>
A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of the number are written together. For example,
a+b<em>i</em>
Here, (a) is the real part while (b) is the imaginary part.
To add the two complex number on the graph, the addition as transition method is used.
In this one complex number is translated to the tip of the other graph. The resultant of addition is equal to the distance between them.
On the graph 4, the transition method of addition is applied.Thus, the graph which correctly shows the point A as the sum of the complex numbers z₁ and z₂ is graph number 4.

we are given
![x(t)=700-30t-15t^2](https://tex.z-dn.net/?f=%20x%28t%29%3D700-30t-15t%5E2%20)
Average rate of change:
we can use formula
![v(t)=\frac{x(t)-x(0)}{t-0}](https://tex.z-dn.net/?f=%20v%28t%29%3D%5Cfrac%7Bx%28t%29-x%280%29%7D%7Bt-0%7D%20%20)
![x(t)=700-30t-15t^2](https://tex.z-dn.net/?f=%20x%28t%29%3D700-30t-15t%5E2%20)
![x(0)=700-30(0)-15(0)^2](https://tex.z-dn.net/?f=%20x%280%29%3D700-30%280%29-15%280%29%5E2%20)
![x(0)=700](https://tex.z-dn.net/?f=%20x%280%29%3D700%20)
now, we can plug value
and we get
![v(t)=\frac{700-30t-15t^2-700}{t-0}](https://tex.z-dn.net/?f=%20v%28t%29%3D%5Cfrac%7B700-30t-15t%5E2-700%7D%7Bt-0%7D%20%20)
now, we can simplify it
![v(t)=\frac{-30t-15t^2}{t}](https://tex.z-dn.net/?f=%20v%28t%29%3D%5Cfrac%7B-30t-15t%5E2%7D%7Bt%7D%20%20)
![v(t)=\frac{t(-30-15t)}{t}](https://tex.z-dn.net/?f=%20v%28t%29%3D%5Cfrac%7Bt%28-30-15t%29%7D%7Bt%7D%20%20)
now, we can cancel t
![v(t)=-30-15t](https://tex.z-dn.net/?f=%20v%28t%29%3D-30-15t%20%20)
so, option-d.............Answer
First:The area of a circle is πr squared. Not r2
Second. The area of the circle HAS to be irrational because π is an irrational number. The answer would be, if solved for a circle with the radius of 0.75, the area would be 0.5625π, which is irrational.
