Are complex numbers the same as real numbers?

Answers

Answer 1

Although every complex number is a real number, not all complex numbers are real numbers.

What connection exists between real numbers and complex numbers?On the number line, the real numbers can be plotted.The number line cannot be used to plot the complex numbers.The symbol designates it.Complex numbers make up all real numbers.Real numbers are not all complex numbers.Although every complex number is a real number, not all complex numbers are real numbers. The symbol Z C Z in mathbb C ZC denotes the collection of all complex numbers.If a number can be expressed as a+bi using the real integers a, b, it is complicated. So, certainly, a complex number can be both real and totally fictitious.

marianne is a five years younger than her friends if the sum of their age is 61 how old is her friend​

Answers

Step-by-step explanation:

let marianne friend age be x and

marianne age be x - 5

if the sum of their age is 61 I.e

x + (x- 5) = 61

x + x - 5 = 61

2x =61 +5

2x = 66

divide both sides by 2

x = 33

so marianne friend age is 33 and

and marrianne age is 33-5 = 28.

Find the area of the shaded segment of the circle​

Answers

Answer:

≈ 0.8 m²

Step-by-step explanation:

________________________________________________

FORMULA FOR FINDING AREA OF SEGMENT :-

[tex]A = r^{2} [\frac{\alpha }{360} \times \pi - (\sin \frac{\alpha }{2} \times \cos \frac{\alpha }{2} )][/tex]

Where :-

A = Area of the segmentr = Radius of the circleα (alpha) = Angle subtended by arc at the center

________________________________________________

Angle subtended by the minor arc at the center = 360° - 300° = 60°

Radius of the circle = 3 m

Area of the segment =

[tex]3^{2} [ \frac{60}{360} \times \pi - (\sin \frac{60}{2} \times \cos \frac{60}{2})][/tex]

[tex]= 9[\frac{1}{6} \times \pi - (\sin 30 \times \cos 30)][/tex]

[tex]= 9[\frac{\pi }{6} - (\frac{1}{2} \times \frac{\sqrt{3} }{2} )][/tex]

[tex]= 9[\frac{\pi }{6} - \frac{\sqrt{3} }{4} ][/tex]

[tex]= 9[\frac{2\pi - 3\sqrt{3} }{12} ][/tex]

[tex]= \frac{9}{12} \times (2\pi - 3\sqrt{3})[/tex]

( Assuming √3 = 1.73 & π = 3.14 )

[tex]= \frac{3}{4} \times (6.28 - 5.19)[/tex]

[tex]= 0.75 \times 1.09[/tex]

[tex]= 0.8175[/tex]

∴ Area of the segment ≈ 0.8 m² (rounding to the nearest tenth)

96 + x Less-than-or-equal-to 149
96 + x Greater-than-or-equal-to 149
96 + x > 149
96 + x < 149

Answers

Answer: Choice A)  96 + x ≤ 149

This is the same as saying "96 + x less than or equal to 149"

====================================================

Explanation:

We start with 96 people already on board. We add on x more people. The x is a placeholder for a positive whole number.

In total, we have 96+x people on the plane. This total must not exceed the max capacity of 149. In other words, the largest value of 96+x is 149.

Since 96+x can be 149 or smaller, we can say 96+x ≤ 149

Step-by-step explanation:

...the population increased 5,9 x 10 6.

The ratio is 64:13

What is ratio?

Ratio is the comparison of two quantities which is obtained by dividing the first quantity by the other. If a and b are two quantities of the same kind and with the same units, such that b is not equal to 0, then the quotient a/b is called the ratio between a and b. Ratios are expressed using the symbol of the colon (:). This means that ratio a/b has no unit and it can be written as a : b

Given data:

Population of china in 2005 =1.3*10^9

population of entire world in 2005 = 6.4*10^9

Now,

ratio= 6.4*10^9/ 1.3*10^9

ratio= 64/13 or 64:13

Find the equation of the line that has a y-intercept of 1 and is perpendicular to the graph of the line 2x + y = 4.

Answers

Answer:

y = 1/2x + 1

Step-by-step explanation:

To be perpendicular to a line is to have the product of the slopes be -1. First, we have to put 2x + y = 4 into slope-intercept form to find the slope of the line. We do this by subtracting 2x on both sides to get that y = -2x + 4. Now, the number that multiplied by -2 is equal to -1 is 1/2, so that is the slope of our line. We can substitute these values into the slope-point equation to find the equation. We would get that y - 1 = 1/2 * (x - 0). This simplifies to y = 1/2x + 1.
