Answer:

The answer is the last one, D, pictured above on the question, I took the test and it showed it was the right one

Step-by-step explanation:

The geometric expression of two complex number is the magnitude r₁*r₂ and the phase is  θ₁ + θ₂.

The complex number is" the combination of real numbers and an imaginary number. The complex number is of the form a + i b".

According to the question,

z, w are the two complex numbers. The distance from its point in the complex plane to the origin (0,0) and the angle formed by the line segment from the origin to the point and the positive half of the x-axis.

The distance or 'magnitude' to the origin is denoted as 'r' and the angle or 'phase' formed denoted as 'θ'. The distance to the origin is called 'magnitude'.

The parameter 'r' and 'θ' related to 'a' along x-axis and 'b' along y-axis.

Euclidean distance formula applying Pythagorean theorem we have

r =  [tex]\sqrt{a^2+b^2}[/tex].

The sine angle is defined to the ratio y-coordinate 'b' to length  'r' and the cosine angle is defined to the ratio x-coordinate 'a' to length 'r'.

sin θ =  [tex]\frac{b}{r}[/tex]  and cos θ = [tex]\frac{a}{r}[/tex].

b = r sin θ; a = r cosθ

When multiplying two complex numbers we by multiplying magnitude together and add two phase. when divide two complex number by dividing the magnitude correspondingly and subtracting the phase from the numerator and the denominator.

Then we have product complex number to the magnitude r₁ and phase θ₁

with a complex number to the magnitude r₂ and the phase θ₂ which gives   the complex number with magnitude r₁ * r₂ and θ₁ + θ₂.

Hence, the geometric representation of z w is with magnitude r₁*r₂  and phase is θ₁ + θ₂.

Step-by-step explanation:

Answer:

A is -8

B is 28

Step-by-step explanation:

Let us rewrite the equation in the standard format of y = mx + b

By = -Ax + 12

y = (-A/B)x + 12/B

Now, since the line is parallel to the line given below, then their slopes must be equal

2x - 7y = 3

7y = 2x - 3

y = (2/7)x - 3/7

slope here is 2/7

Thus;

-A/B = 2/7

let’s now insert the point that the line passes through

We have;

1 = (-A/B)2 + 12/B

but -A/B = 2/7

1 = 4/7 + 12/B

12/B = 1 - 4/7

12/B = 3/7

B = (7 * 12)/3

B = 28

-A/28 = 2/7

-7A = 56

A = 56/-7

A = -8

Answer: Slope=–2, y-intercept= (0, –3), and x-intercept (–3/2, 0).

Step-by-step explanation:

Slope of the graph is -2 and y intercept is -3.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given graph equation is g(x) = -2x - 3

g(x) equal to minus two x minus three.

By the equation of slope intercept form y=mx+c

where m is the slope and c is the y intercept.

m=-2 and c=-3

Let us plot a graph by data

x          0         1          2        3        4

g(x)     -3        -5        -7       -9       -11

Hence slope of the graph is -2 and y intercept is -3.

1/2 and 1/10

The value of fractions whose sum is 3/5 are, 1/2 and 1/10.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

We have to given that;

Noah is thinking of two fractions that have a sum of 3/5 each fraction has a numerator of 1.

Now, Let two fraction with each has a numerator of 1 are,

⇒ 1/2 and 1/10

Now, We can add these fraction, we get;

⇒ 1/2 + 1/10

⇒ (10 + 2) / 20

⇒ 12/20

⇒ 3/5

Thus, The value of fractions whose sum is 3/5 are, 1/2 and 1/10.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

You need to multiply 14 x 220%

220% = 2.2

So 14 * 2.2 = 30.8

Another way to think of it would be: 100% of 14 = 14

So 200% would mean you need to double that, which would be 28

Then the final 20% would add 2.8

Add 28 + 2.8 = 30.8

Answer:

y=60 degrees

x=90 degrees

Step-by-step explanation:

If you look at x, you can tell by it's angle that it is 90 degrees. A square has 4 sides with 90 degrees on each side, that angle is 1/4 of a square, making it a 90 degree angle, and a triangle has 3 sides, all 60 degrees, if you look at y, you can see that angle is 1/3 of a triangle, giving it a 60 degree angle.

Answer:

Step-by-step explanation:

If x = -5

Entonces f(X) = (-5) - 5 = -10

If x = 0

So f(x) = (0) - 5 = -5

When x = 5

So f(x) = (5) - 5 = 0

Don't pay attention to the "F", it just means they want the whole result of the operation if you replaced "x" with a number.

Remember that there are negative and positive numbers.

Any number below zero is negative.
