The complex number _______ lies in the shaded area of the graph. The complex number _______ does not lie in the shaded area.
Anastaziya [24]
Think of imaginary numbers on a complex plane as coordinates - take the real part, that's the x coordinate, the imaginary part that's the y coordinate.

Therefore, for the first blank, -1+3i lies in the shaded area, because its coordinates are (-1,3).
And following on from that for the second one, -4i does not lie in the shaded area, since its coordinates are (0,-4).

Tl;dr is taking a complex number a+bi and placing it on a complex plane, it will have coordinates (a,b)

Perimeter of a quarter circle is 17.85 what is the quarter circles radius
givi [52]

The radius of the given circle  is 2.84 units

Step-by-step explanation:

Step 1 :

Given

The perimeter of a quarter table is 17.85

We need to find the circle's radius.

Step 2 :

The circle's perimeter is given by the formula, 2 \pi r where r represents the circle's radius

So from this we have ,

2 \pi r = 17.85

We can determine the radius by dividing the perimeter value by 2 \pi

= >  r = 17.85 divided by 2 \pi r

        = 2.84 [ taking  \pi  = \frac{22}{7}]

Step 3 :

Answer :

The radius of the given circle  is 2.84 units

Lines m and n are parallel. find the value of x.<br> A. 15<br> B. 20<br> C. 65<br> D. 115
torisob [31]

Answer:

Option B, x = 20

Step-by-step explanation:

<u>Step 1:  Make an equation</u>

The values of 65 degrees and (3x + 5) are equal.

65 = 3x + 5

<u>Step 2:  Subtract 5 from both sides</u>

65 - 5 = 3x + 5 - 5

60 = 3x

<u>Step 3:  Divide both sides by 3</u>

60 / 3 = 3x / 3

<em>20 = x</em>

<em />

Answer:  Option B, x = 20
