Step-by-step explanation:

The number line sketched above shows the positions of both points A and B.

They both are the same distance from the point zero. However, while the measure of the distance is always a positive value, the value on the number line to the left is negative, while that on the right is positive. Therefore, adding both values (same value/distance) on both the left and rigt side will result in 0.

The linear equality for the given graph is x > 0.

Option (B) is correct.

What is linear equality?

In mathematics, a linear inequality is an inequality that involves a linear function. A linear inequality contains one of the symbols of inequality. It shows the data which is not equal in graph form.

The hollow circle in the linear equality shows that the point should be excluded and the line is going towards the positive x-axis.

So we can prepare the linear equality as

                       x > 0

Hence, the linear equality for the given graph is x > 0.

a) The current phasor I can be rewritten as I = 22∠120° A. The expression for the current in the time domain is i(t) = 22√2cos(ωt + 120°), where ω is the angular frequency.

b) The voltage phasor V can be rewritten as V = 220∠30° V. The equation for the voltage in the time domain is v(t) = 220√2cos(ωt + 30°), where ω represents the angular frequency.

a) In electrical engineering, phasors are used to represent sinusoidal quantities, such as currents and voltages, in a complex plane. The phasor I = 22∠120° A consists of a magnitude of 22 A and an angle of 120°. To convert this phasor into the time domain, we need to express it as a time-varying sinusoidal function.

In the time domain, sinusoidal functions can be represented using the cosine function. The general expression for a sinusoidal function in the time domain is given by i(t) = A√2cos(ωt + θ), where A is the amplitude, ω is the angular frequency, t is time, and θ is the phase angle.

To convert the given phasor into the time domain, we can use the following relationships:

Magnitude: A = 22

Amplitude: A√2 = 22√2

Phase angle: θ = 120°

Therefore, the current in the time domain is given by i(t) = 22√2cos(ωt + 120°).

b) Similarly, the voltage phasor V = 220∠30° V has a magnitude of 220 V and an angle of 30°. To express this phasor in the time domain, we follow the same process as above.

Using the relationships:

Magnitude: A = 220

Amplitude: A√2 = 220√2

Phase angle: θ = 30°

The voltage in the time domain is given by v(t) = 220√2cos(ωt + 30°).

In both cases, the time domain representation of the phasors allows us to analyze and calculate the behavior of the sinusoidal signals in practical applications, such as in electrical circuits or power systems.

The slope of the hypotenuses of two triangles that are the same area: triangle 1 and 4.

In a right triangle, the longest side that is opposite the right angle of the triangle is called the hypotenuse of the triangle.

How to Find the Slope of a Line?

Slope = rise/run = vertical distance/horizontal distance across a line.

Slope of the hypotenuse of triangle 1 = rise/run = -4/2 = -2.

Slope of triangle 2 = rise/run = -6/6 = -1.

Slope of triangle 3 = rise/run = -3/6 = -1/2.

Slope of triangle 4 = rise/run = -8/4 = -2.

Therefore, triangle 1 and triangle 4 have hypotenuse that have the same slope of -2.

From the given inequality the only value that lies between the two numbers is 12.7. Hence, option C is the correct answer and value of s = 12.7.

A mathematical statement known as an inequality describes the difference between two numbers or expressions, often stating that one is bigger than, less than, or not equal to the other. The symbols larger than and less than are frequently used to denote inequality. For instance, the inequality y > 10 asserts that y is larger than 10 whereas the inequality x < 5 states that x is smaller than 5.

Given that, 3 > √(s) < 7.

Square on both sides of inequality:

3² > s > 7²

9 > s > 49

Thus, any value of s between 9 and 49 (exclusive) satisfies the inequality.

From the given equation the only value that lies between the two numbers is 12.7.

Hence, option C is the correct answer.

The value of  variable x in the equation is 16.

The equation represented as follows:

x + 14 + x³ = 78

The value x is the variable.

A variable is number represented with a letter in an equation.

Therefore,

x + 14 + 3x = 78

subtract 14 from both sides of the equation

x + 3x + 14 - 14 = 78 - 14

x + 3x = 64

Therefore,

4x = 64

divide both sides by 4

The scenario in which an athlete cuts the time it takes to complete a 10K race by 5% each week represents an exponential function.

An exponential function is a mathematical function in which the independent variable is an exponent. It is characterized by a constant ratio between successive values.

In the given scenarios, the first two options involve a fixed amount or average (monthly rent payments or number of patrons per hour) and do not demonstrate exponential growth or decay. These scenarios can be represented by linear functions.

The third option, where an athlete cuts the time it takes to complete a 10K race by 5% each week, represents exponential decay. The time reduction each week can be expressed as a percentage of the previous week's time, resulting in a constant ratio between successive time values. This is a characteristic of exponential functions.

The fourth option describes the volume of a cube, which is calculated by raising the length of the side to the third power. This is an example of a polynomial function, specifically a cubic function, rather than an exponential function.

Therefore, the scenario in which an athlete cuts the time it takes to complete a 10K race by 5% each week represents an exponential function.

Answer:

here you go man , just expand the bracket and then compare values that are in the same position, this concept follows the general equation of x^2+bx+c

Answer:

\(a = 11 \: , \: b = 121\)

Step-by-step explanation:

\((x + a) {}^{2} = x {}^{2} + 22x + b\)

\(expanding \: (x + a) {}^{2} \)

\((x + a)(x + a) = x {}^{2} + 2ax + a {}^{2} \)

\(x {}^{2} + 2ax + a {}^{2} = x {}^{2} + 22x + b\)

\(x {}^{2} ; \: 1 = 1\)

\(x; \: 2a = 22......(i)\)

\(constant; \: a {}^{2} = b......(ii)\)

From(i);

From(i);2a = 22

From(i);2a = 22a = 22/2

From(i);2a = 22a = 22/2a = 11

From(ii);

a² = b

11² = b

121 = b

Therefore a = 11, b = 121.

The equation for a cosecant function with vertical asymptotes found at x = pi/3 + pi/3 * n, where n is an integer, is given by: cosec(x) = A/(x - pi/3 - pi/3 * n)

The cosecant function is the reciprocal of the sine function, i.e., cosec(x) = 1/sin(x). The vertical asymptotes of the cosecant function occur where the denominator becomes zero, i.e., at x = pi/3 + pi/3 * n. To determine the amplitude A of the function, we need to find the value of cosec(x) at any point where it is defined. Let's choose x = pi/2 as such a point, where sin(x) = 1. Therefore, cosec(pi/2) = 1, which gives us:

cosec(x) = A/(x - pi/3 - pi/3 * n) = 1

Solving for A, we get:

A = 1/(pi/2 - pi/3 - pi/3 * n) = 6/(pi - 2pi*n)

Therefore, the equation for the cosecant function with vertical asymptotes found at x = pi/3 + pi/3 * n is:

cosec(x) = 6/[(pi - 2pin)(x - pi/3 - pi/3 * n)]
