The distance between pair of parallel lines with the given equation

y=-6 y=1 is 7 units

Parallel lines are any two or more lines that lie in the same plane but never cross one another. Both have the same slope and are equally distant from one another. No matter how far we extend a parallel line, it will always remain straight.

The fundamental characteristics listed below make it simple to recognize parallel lines.

The two lines have the coefficient of x, zero. So, the slopes are 0.

Therefore, the lines are horizontal lines passing through y = −6 and y = 1.

The perpendicular distance between the these horizontal lines is

1 - (-6) = 7 units.

The acceleration of the dog is approximately 1.83 meter per second² .

Acceleration is defined as the rate of change of velocity . The change in velocity per unit time is acceleration.

In the given problem the dog started from rest and achieved the final velocity of 5.5 m/s.

Let us use Newton's laws to write the equation:

v = u + at , where v is the final velocity , u is the initial velocity , a is acceleration and t is time.

The dog starts from rest so the initial velocity is 0.

given v=5.5 /s and t = 3 seconds

putting the values we get:

v = u + a t

or , 5.5 = 0 + 3a

or, a = 5.5/3 meters per seconds²

or, a = 1.8333... m/s²

The cylinder's total surface area includes the area of the curving surface as well as the areas of the two circle-shaped bases of the cylinder.

The area of the two bases and the area of the curved surface are added to determine the cylinder's total surface area. Consequently, the following is the formula for the cylinder's total surface area:

Area of the two bases plus the area of the curved surface equals the cylinder's total surface area. Due to the cylinder's round bottoms, their combined area will be equal to r2 + r2. We already know that a cylinder's curved surface area is 2rh.

(r2 + r2 + 2rh) is the cylinder's total surface area.

The solution of the system of equations involving 3x + 7y = 15 and 5x + 2y = -4 is  (-2 , 3).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

3x + 7y = 15     (equation 1)

5x + 2y = -4     (equation 2)

Using the first equation, find the value of one variable, lets say x, in terms of the other.

3x + 7y = 15     (equation 1)

3x = 15 - 7y

x = 5 - (7/3)y

Substitute the equation of x to the second equation.

5x + 2y = -4     (equation 2)

5[5 - (7/3)y] + 2y = -4

25 - (35/3)y + 2y = -4

Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.

25 - (35/3)y + 2y = -4

- (35/3)y + 2y = -4 - 25

-(29/3)y = -29

y = 3

Substitute the value of y in the equation of x.

x = 5 - (7/3)(3)

x = 5 - 7

x = -2

Hence, the solution of the given system of equations is (-2 , 3).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

From the graph of the functions, we have that:

This means that g(x) is a shift right of 2 units of f(x), that is:

g(x) = f(x - 2).

Step-by-step explanation:

what is B in your question ? you did not tell us.

since you mention "fraction", I assume B is the slope of a line ?

if that is the case, please remember, the slope is (y coordinate change / x coordinate change) when going from one point of the line to another.

the way you phrased it I assume the slope was originally negative.

that means either the y difference or the x difference was negative (but not both, otherwise it would have been a positive fraction again).

let's look at what happens, when things get reflected across the y axis :

things go from the left side (negative x values) to the right side (positive x values) of the y axis or vice versa.

and things stay on the same side of the x axis (either above the x-axis with positive y values, or below the x-axis with negative y values).

so, that reflection causes the x values to flip their sign, but the y values stay the same.

so, if y was originally negative, then x must have been positive. after the reflection x is now negative too, that makes the y/x fraction -/- = +/+ positive.

if y was originally positive, then x must have been negative. after the reflection x is now positive too, that makes the y/x fraction +/+ positive.

therefore, in every case, the reflected slope fraction must be positive.

The maximum allowable weight for a disc with circumference 66.92 centimeters Round to the nearest tenth is 176.9 grams.

A circle's outside boundary is called the circumference and can be measured, or calculated, by using

Circumference = 2πr

where r is the radius of circle.

Now it is given that,

the maximum weight, w of a disc in grams is 8.3 times the diameter, d in centimeters

⇒ w ≤ 8.3d

and  the maximum allowable weight for a disc with circumference 66.92 centimeters

So, Circumference = πd   [∵ d = 2r]

∴ 66.82 = πd

⇒ d = 66.82π

Thus,  w ≤ 8.3*66.82π grams

⇒ w ≤ 176.89 grams

Round to the nearest tenth, w ≤ 176.9 grams

n(A) is the number of favorable outcomes

n(S) is the total number of events in the sample space.

Given,

At a carnival, the object of a game is to throw a dart at the board and hit region III.

Here we need to find the probability that it hits region IV.

Consider the board was look like the following figure.

Then based on the given figure,

First, we have to find the total area of the board and the area of the required region.

And then we have to compare it to calculate the Probability.

So, the total area of the board is,

=> total area of the board = (10 + 30)(10 + 15)

=> total area of the board = 1000 in²

Now, the The area of the region IV is

=> Area = (10)(30)

=> Area = 300 in²

Therefore, the probability that it hits region IV is

=> P = 300/1000

=> P = 30/100

=> P = 30%
