In the given picture with 4 lines l, m and r, s. The l and m, r and s line are parallel lines.

Given that,

There is a picture with 4 lines l, m and r, s.

We have to check that those lines are parallel or not

To check that the line are parallel we have a condition.

If two lines are cut by the transversal and corresponding angles are congruent then we can say that those 2 lines are parallel.

In the figure we can see that ∠2 and∠6 are congruent.

So, we can say that lines r and s are parallel lines.

Similarly,

In the figure we can see that ∠1 and∠7 are congruent.

So, we can say that lines l and m are parallel lines.

The magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart is 2N.

The repulsive force between two charges = (k q₁ q₂)/r²

q₁ q₂ are the charges

r is distance between the charges

k= 9×10⁹ Nm²C²

F= (500μC) (+100μC)9×10⁹/25

 = 2N

A movement between two charges that are same or comparable is referred to as repulsion. The tension between two electrons (negative charge). Two charges of a different sort are drawn toward one another by the force of attraction, which is defined as "a force between two charges that are distinct or different."

At a distance, magnetism is an attractive or repulsive force. The repulsive force gives rise to a metric that measures how a system's gravitational mass changes. According to the force-based approach, the forces that attract and repel other atoms come from their subatomic arrangement and control how they behave.

Answer:

[tex]\textsf{b)} \quad -\dfrac{3\sqrt{13}}{13}[/tex]

Step-by-step explanation:

Trigonometric ratios

[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]

where:

[tex]\textsf{If}\; \tan(\theta)=-\dfrac{2}{3} \implies \sf O=2 \; \textsf{and} \; A=3.[/tex]

Use Pythagoras Theorem to calculate the length of the hypotenuse:

[tex]\sf \implies O^2+A^2=H^2[/tex]

[tex]\implies \sf H=\sqrt{O^2+A^2}[/tex]

[tex]\implies \textsf{H}=\sqrt{2^2+3^2}[/tex]

[tex]\implies \textsf{H}=\sqrt{13}[/tex]

Therefore, substituting the values of A and H into the cosine ratio:

[tex]\implies \cos \theta=\dfrac{3}{\sqrt{13}}[/tex]

[tex]\implies \cos \theta=\dfrac{3}{\sqrt{13}}\cdot \dfrac{\sqrt{13}}{\sqrt{13}}[/tex]

[tex]\implies \cos \theta=\dfrac{3\sqrt{13}}{13}[/tex]

As the terminal side of the angle is in Quadrant II, and cosine is negative in Quadrants II and III, the exact value of cos(θ) is:

[tex]\implies \cos \theta=-\dfrac{3\sqrt{13}}{13}[/tex]

Using relations in a right triangle, it is found that the distance between the towns is of 15 km.

The relations in a right triangle are given as follows:

For the first town, we have that:

Hence:

tan(37º) = xA/10

xA = 10 x tan(37º).

xA = 7.5 km.

For the second town, we have that:

Hence:

tan(66º) = xB/10

xB = 10 x tan(66º).

xB = 22.5 km.

The greatest common factor for 4x³+16x² +8x is 4x(x2- 4x - 2).

This solution focuses on simplification:

4x(x2-4x-2)

(22x3-24x2) -8x

Take similar factors aside:

4x3-16x2-8= 4x(x2-4x-2)

Factoring  x2 - 4x - 2

x2 is the initial term, and it has a coefficient of 1.

The coefficient of the intermediate term, which would be -4x, is 4.

"The constant," the final term, is -2.

Multiply the constant by the coefficient of the first term. 1  -2 = -2

The second step is to find two -2 factors whose sum is equal to the -4 coefficient of the middle word.

-2 + 1 = -1

-1 + 2 = 1

The rate of change of the linear equation that has the given points on its graph is; -2.

The rate of change of a linear function can be determined by using the following formula:

Rate of change = change in y / change in x = y2 - y1 / x2 - x1.

Given the following points on a graph of a linear function:

​(−5​,4​) = (x1, y1)

​(−2​,−2​) = (x2, y2)

Plug in the values

Rate of change = change in y / change in x = (-2 - 4) / (-2 -(-5))

Rate of change = -6 / 3

Rate of change = -2 / 1

Rate of change = -2

The required volume of the box is given as 936 cubic centimeters.

Given that, A box of Tyler's favorite snack, Cheesy Snaps, is 13 centimeters tall and 6 centimeters wide. It has twice as long as it is wide.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
height  = 2 × width
height = 2 × 6 = 12
The volume of the box = length × width  × height
                             = 13 × 6 × 12 = 936

The slope of line: 1. m= 6 , 2. m= -6 , 3. m= 2.5,  4. m= .5

The slope of the line :

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Tan θ = Δy/Δx can also represent the slope of the line

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope,

m = Change in y-coordinates/Change in x-coordinates

m = (y2 – y1)/(x2 – x1)

Therefore, based on the above formula, we can easily calculate the slope of a line between two points.

In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,

Slope, m = Rise/Run

1.

(-1,-1) & (0,5)

m = (y2 – y1)/(x2 – x1)

m = (5 – (-1)) /(0– (-1))

m = (5 +1)/(0 +1)

m = (6)/(1)

m = 6

2.

(3,5) & (4,-1)

m = (-1 – 5)/(4 – 3)

m = (-6)/(1)

m = -6

3.

(2,1)  & (4,6)

m = (6 – 1)/(4 – 2)

m = (5)/(2)

m = 2.5

4.

(-5,-2) & (3,2)

m = (2 – (-2))/(3 – (-5))
