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.

How do i find square root of a variance
Alex17521 [72]

Answer:

Discrete variables

Calculate the mean.

Subtract the mean from each observation.

Square each of the resulting observations.

Add these squared results together.

Divide this total by the number of observations (variance, S2).

Use the positive square root (standard deviation, S).

G(-2, 5), H(6, 5), J(6, -1)<br> 17. Find the coordinates of the centroid.
adell [148]

The coordinates of centroid are: (10/3, 3)

Step-by-step explanation:

The formula for calculating centroid of a triangle is:

(x,y) = (\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})

Here (x1,y1) are the coordinates of first vertex

(x2,y2) are the coordinates of second vertex

(x3,y3) are the coordinates of third vertex

Given:

G(-2,5) = (x1,y1)

H(6,5) =(x2,y2)

J(6,-1) = (x3,y3)

Let I be the centroid of the triangle

Putting the values in the formula

I(x,y) = (\frac{-2+6+6}{3},\frac{5+5+-1}{3})\\= (\frac{10}{3},\frac{9}{3})\\=(\frac{10}{3},3)

The coordinates of centroid are: (10/3, 3)

Answer:

185.04 mm

Step-by-step explanation:

The perimeter is 1/2 of the circumference plus the diameter

We need to go around the semicircle on the outside plus across the middle

1/2 C + d

1/2 2*pi * r  + 2r

pi *r +2r

3.14 (36)   + 2 (36)

113.04+72
