Answer:

the slope is 2/3 and the y-intercept is -2

The slope and the y-intercept of the linear function represented by the graph are 2/3 and -2, respectively.

What is meant by linear function?

A linear function is one that, when graphed, produces a straight line. Thus, non-linear functions are any non-linear functions. Although graphing is the quickest way to determine whether a function is linear or non-linear, we can also determine linearity from its input/output table or equation.

So the way to describe linear functions is that for any given change in x, the change in y will always be the same value. You're dealing with a linear function if it always returns the same value.

Therefore,

Any line's slope - intercept form is

y = mx + c

Where m = Slope of the line

c = y - intercept of the line

The given points in this case are (0, - 2) and

The equation of the line passing through the points (0, - 2) and (3, 0) is now complete.

\(&\frac{y+2}{x-0}=\frac{0+2}{3-0} \\\)

\(&\Longrightarrow \frac{y+2}{x}=\frac{2}{3} \\\)

\(&\Longrightarrow y+2=\frac{2}{3} x \\\)

\(&\Longrightarrow y=\frac{2}{3} x-2\)

Which of the slope - intercept form y = mx + c

Where m = 2/3  and c = -2

Thus, Two/thirds is the slope, and -2 is the y-intercept.

Domain:{-3,-2,-1,2,6}

Range:{0.5,0,-1.5,3,2}.

How to find the domain and range of the functions?

1) The function f(x) = 4 - 4x

Take Domain:{0,1,3,5,6}

If, we take x=0 and put in the function then we get

f(x)=4-0

f(x)=4

put x=1

f(x) = 4 - 4 =0

put x=3 then we get

f(x)=4-12=--8

put x=5 them we get

f(x)=4-20=-16

put x=6 then we get

f(x)=4-24=-20

Therefore ,range:[-20,-16,-8,0,4}

2) The function f(x)=5x-3

Take domain{-2,-1,0,3,4}

Now, put x=-2 in the function then we get

f(x) = -13

now put x=-1 then we get

Put x=0 then we get

f(x)=0-3=-3

Put x=3 then we get

f(x)=15-3=12

Put x=4 then we get

f(x)=20-3=17

Therefore , range:{-13,-8,-3,12,17}

3) The function f(x)=-10x

Take domain:{-4,-2,0,2,4}

Put x=-4 in the function then we get

f(x)=40

Put x= -2 then we get

f(x)=20

Put x=0 then we get

f(x)=0

Put x=2 then we get

f(x)=-20

Put x=4 then we get

f(x)=-40

Therefore , range :{-40,-20,0,20,40}

4) The function f(x)= (3/x) + 1.5

Take domain:{-3,-2,-1,2,6}

Put x= -3 in the taken function then we get

f(x)=-1+1.5=0.5

put x=-2 then  we get

f(x)= -1.5+1.5=0

Put x=-1 then we get

f(x)=-3+1.5=-1.5

Put x= 2 then we get

f(x)=1.5+1.5=3

Put x= 6 then we get

f(x)=0.5+1.5=2

On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, 2).

Answers

Using shifting concepts, we get that the graph that represents the translation g(x) = |x + 2| as a solid line is:

On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).

--------------------------------------------------

Shifting a function f(x) a units to the left is the same as finding f(x + a).

--------------------------------------------------

The vertex of the function f(x) = |x| is at the point where x = 0, and thus, f(x) = 0. Thus, the vertex of the dashed line is at (0,0).The vertex of the function g(x) = |x + 2| is at the point where \(x + 2 = 0 \rightarrow x = -2\), g(-2) = |-2 + 2| = 0. Thus, the vertex of the solid line is at (-2,0).

Thus, the correct option is:

On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).

At the end of the exercises, there are are the graphs of those two functions, considering the dashed line as the red line and the solid line as the blue line.

Suppose another refrigerator costs $1000 and $25 a year for electricity. Write an expression for the total cost for the refrigerator over x years. 3. Over 10 years which refrigerator costs the most? By how much? 4. In how many years will the total costs for the two refrigerators be equal?

Answers

Hello!

1. Write an expression for the cost to buy and run this refrigerator for x years.

costs: $700

each year: $85

So, for x years, the expression will be:

\(f\mleft(x\mright)=85x+700\)2. Write an expression for the total cost for the refrigerator over x years.

Let's do the same steps:

costs: $1000

each year: $25

So, for x years, we have:

\(g(x)=25x+1000\)3. Over 10 years which refrigerator costs the most? By how much?

To solve this question, we just need to replace where is x by 10 in each of the functions, look:

First refrigerator:

\(\begin{gathered} f(x)=85x+700 \\ f(10)=(85\cdot10)+700 \\ f(10)=850+700 \\ f(10)=1550 \end{gathered}\)

Second refrigerator:

\(\begin{gathered} g(x)=25x+1000 \\ g(10)=(25\cdot10)+1000 \\ g(10)=250+1000 \\ g(10)=1250 \end{gathered}\)

So, the first refrigerator costs the most. The difference between the two refrigerators equals $300.

4. In how many years will the total costs for the two refrigerators be equal?

To find the value which equals the two functions, we just need to equal them, look:

\(\begin{gathered} 85x+700=25x+1000 \\ 85x-25x=1000-700 \\ 60x=300 \\ x=\frac{300}{60} \\ x=5 \end{gathered}\)

In five years the costs will be equal, let's prove it:

f(5) = g(5)

(85*5) +700 = (25*5) +1000

425 + 700 = 125 + 1000

1125 = 1125

1. Find the area of a regular octagon. Each side is 12 m.

2. The perimeter of a regular polygon is 72 feet. An exterior angle of the polygon measures 40°. Find the length of each side.

3. If the perimeter of a regular pentagon is 50 in. Find the area. Show a drawing and work please.

Answers

Answer:

1)  695.3 m²

2)  8 ft

3)  172.0 in²

Step-by-step explanation:

Question 1

To find the area of a regular polygon, we can use the following formula:

\(\boxed{\begin{minipage}{5.5cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{s^2n}{4 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the side length.\\\end{minipage}}\)

Given the polygon is an octagon, n = 8.

Given each side measures 12 m, s = 12.

Substitute the values of n and s into the formula for area and solve for A:

\(\implies A=\dfrac{(12)^2 \cdot 8}{4 \tan\left(\dfrac{180^{\circ}}{8}\right)}\)

\(\implies A=\dfrac{144 \cdot 8}{4 \tan\left(22.5^{\circ}\right)}\)

\(\implies A=\dfrac{1152}{4 \tan\left(22.5^{\circ}\right)}\)

\(\implies A=\dfrac{288}{\tan\left(22.5^{\circ}\right)}\)

\(\implies A=695.29350...\)

Therefore, the area of a regular octagon with side length 12 m is 695.3 m² rounded to the nearest tenth.

\(\hrulefill\)

Question 2

The sum of an interior angle of a regular polygon and its corresponding exterior angle is always 180°.

If the exterior angle of a polygon measures 40°, then its interior angle measures 140°.

To determine the number of sides of the regular polygon given its interior angle, we can use this formula, where n is the number of sides:

\(\boxed{\textsf{Interior angle of a regular polygon} = \dfrac{180^{\circ}(n-2)}{n}}\)

Therefore:

\(\implies 140^{\circ}=\dfrac{180^{\circ}(n-2)}{n}\)

\(\implies 140^{\circ}n=180^{\circ}n - 360^{\circ}\)

\(\implies 40^{\circ}n=360^{\circ}\)

\(\implies n=\dfrac{360^{\circ}}{40^{\circ}}\)

\(\implies n=9\)

Therefore, the regular polygon has 9 sides.

To determine the length of each side, divide the given perimeter by the number of sides:

\(\implies \sf Side\;length=\dfrac{Perimeter}{\textsf{$n$}}\)

\(\implies \sf Side \;length=\dfrac{72}{9}\)

\(\implies \sf Side \;length=8\;ft\)

Therefore, the length of each side of the regular polygon is 8 ft.

\(\hrulefill\)

Question 3

The area of a regular polygon can be calculated using the following formula:

\(\boxed{\begin{minipage}{5.5cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{s^2n}{4 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the side length.\\\end{minipage}}\)

A regular pentagon has 5 sides, so n = 5.

If its perimeter is 50 inches, then the length of one side is 10 inches, so s = 10.

Substitute the values of s and n into the formula and solve for A:

\(\implies A=\dfrac{(10)^2 \cdot 5}{4 \tan\left(\dfrac{180^{\circ}}{5}\right)}\)

\(\implies A=\dfrac{100 \cdot 5}{4 \tan\left(36^{\circ}\right)}\)

\(\implies A=\dfrac{500}{4 \tan\left(36^{\circ}\right)}\)

\(\implies A=\dfrac{125}{\tan\left(36^{\circ}\right)}\)

\(\implies A=172.047740...\)

Therefore, the area of a regular pentagon with perimeter 50 inches is 172.0 in² rounded to the nearest tenth.

Answer:

1.695.29 m^2

2.8 feet

3. 172.0477 in^2

Step-by-step explanation:

1. The area of a regular octagon can be found using the formula:

\(\boxed{\bold{Area = 2a^2(1 + \sqrt{2})}}\)

where a is the length of one side of the octagon.

In this case, a = 12 m, so the area is:

\(\bold{Area = 2(12 m)^2(1 + \sqrt{2}) = 288m^2(1 + \sqrt2)=695.29 m^2}\)

Therefore, the Area of a regular octagon is 695.29 m^2

2.

The formula for the exterior angle of a regular polygon is:

\(\boxed{\bold{Exterior \:angle = \frac{360^o}{n}}}\)

where n is the number of sides in the polygon.

In this case, the exterior angle is 40°, so we can set up the following equation:

\(\bold{40^o=\frac{ 360^0 }{n}}\)

\(n=\frac{360}{40}=9\)

Therefore, the polygon has n=9 sides.

Perimeter=72ft.

We have

\(\boxed{\bold{Perimeter = n*s}}\)

where n is the number of sides in the polygon and s is the length of one side.

Substituting Value.

72 feet = 9*s

\(\bold{s =\frac{ 72 \:feet }{ 9}}\)

s = 8 feet

Therefore, the length of each side of the polygon is 8 feet.

3.

Solution:

A regular pentagon has five sides of equal length. If the perimeter of the pentagon is 50 in, then each side has a length = \(\bold{\frac{perimeter}{n}=\frac{50}{5 }= 10 in.}\)

The area of a regular pentagon can be found using the following formula:

\(\boxed{\bold{Area = \frac{1}{4}\sqrt{5(5+2\sqrt{5})} *s^2}}\)

where s is the length of one side of the Pentagon.

In this case, s = 10 in, so the area is:

\(\bold{Area= \frac{1}{4}\sqrt{5(5+2\sqrt{5})} *10^2=172.0477 in^2}\)

One of the lamp posts at a shopping center has a motion detector on it, and the equation (x+16)2 + (y-13)² = 36 describes the boundary within which motion can be sensed. What is the greatest distance, in feet, a person could be from the lamp and be detected? A. 6 ft B. 12 ft C. 36 ft D. 72 ft​

Answers

The greatest distance, in feet, a person could be from the lamp and be detected is: B. 12 ft

How to find the  greatest distance?

The equation (x+16)² + (y-13)² = 36 describes a circle with center (-16,13) and radius 6. The motion detector on the lamp post can detect motion within this circle.

To find the greatest distance a person could be from the lamp and still be detected, we need to find the diameter of the circle, which is equal to twice the radius. Therefore, the greatest distance a person could be from the lamp and still be detected is 2(6) = 12 feet.

Answers

The linear function that describes the distance (in miles) is therefore y = 65x + 80

How to solve for the linear function

We have to find the slope and the intercept in other to get the linear function

The data points are:

(1, 145) and (3, 275).

m = (y2 - y1) / (x2 - x1)

fixing the data points we have

m = (275 - 145) / (3 - 1)

Answers

Answer:

Step-by-step explanation:

Since, ABCDEF is a regular hexagon,

Measure of central angle of a regular polygon = \(\frac{360}{n}\)

where n = number of sides of the polygon

Measure of central angle of regular hexagon = \(\frac{360}{6}\) = 60°

That means when we rotate a regular hexagon by an angle in the multiple of 60°, hexagon overlaps itself.

Therefore, by the rotation of 240° clockwise, point C will replace the position of point A.

Image of hexagon ABCDEF will become CDEFAB.

Similarly, after rotation by 120° counterclockwise about the center image hexagon will be EDCBAF.

prove that there exist only five regular polyhedron​

Answers

To prove that there are only these five regular polyhedra, we can consider Euler's polyhedron formula, which states that for any convex polyhedron, the number of vertices (V), edges (E), and faces (F) satisfy the equation V - E + F = 2.

Proving there exist Five Regular Polyhedron

The five regular polyhedra, also known as the Platonic solids, are the only convex polyhedra where all faces are congruent regular polygons, and the same number of polygons meet at each vertex.

The five regular polyhedra are:

1. Tetrahedron: It has four triangular faces, and three triangles meet at each vertex.

2. Cube: It has six square faces, and three squares meet at each vertex.

3. Octahedron: It has eight triangular faces, and four triangles meet at each vertex.

4. Dodecahedron: It has twelve pentagonal faces, and three pentagons meet at each vertex.

5. Icosahedron: It has twenty triangular faces, and five triangles meet at each vertex.

To prove that there are only these five regular polyhedra, we can consider Euler's polyhedron formula, which states that:

"for any convex polyhedron, the number of vertices (V), edges (E), and faces (F) satisfy the equation V - E + F = 2".

For regular polyhedra, each face has the same number of sides (n) and each vertex is the meeting point of the same number of edges (k). Therefore, we can rewrite Euler's formula for regular polyhedra as:

V - E + F = 2  

=>  kV/2 - kE/2 + F = 2  

=>  k(V/2 - E/2) + F = 2

Since each face has n sides, the total number of edges can be calculated as E = (nF)/2, as each edge is shared by two faces. Substituting this into the equation:

k(V/2 - (nF)/2) + F = 2  

=>  (kV - knF + 2F)/2 = 2  

=>  kV - knF + 2F = 4

Now, we need to consider the conditions for a valid polyhedron:

1. The number of faces (F), edges (E), and vertices (V) must be positive integers.

2. The number of sides on each face (n) and the number of edges meeting at each vertex (k) must be positive integers.

Given these conditions, we can analyze the possibilities for different values of n and k. By exploring various combinations, it can be proven that the only valid solutions satisfying the conditions are:

(n, k) pairs:

(3, 3) - Tetrahedron

(4, 3) - Cube

(3, 4) - Octahedron

(5, 3) - Dodecahedron

(3, 5) - Icosahedron

Therefore, there exist only five regular polyhedra.

Answer:

\(p=36^{\circ}\)

Step-by-step explanation:

We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is \(90^{\circ}\).

Because all the angles of a triangle sum to \(180^{\circ}\), we have that \(p+54+90=180\).

We combine like terms on the left side to get \(p+144=180\).

We subtract \(144\) on both sides to get \(p=36\).

Loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.

What is a sound wave?

When energy moves through a medium (such as air, water, or any other liquid or solid matter), it creates a pattern of disturbance known as a sound wave that propagates away from the sound source.

When an object vibrates, sound waves are produced that are similar to pressure waves, like when a phone rings.

Pitch, intensity, and timbre are three key components of the field of sound psychology or psychoacoustics. People can distinguish the harmonics of a complex periodic sound wave under certain conditions thanks to the way that humans perceive sound and music.

Thus, loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.

When adding data into circular buffer, you append at the next position of last item in your buffer. If the buffer is full, you overwrite the first item. When removing data from the circular buffer, you remove from the first item in your buffer. If the buffer is empty, then you display an error message. Here is how our circular buffer operates: 1. Create a circular buffer class to implement the circular buffer operations. 2. Use a Python list to represent the buffer. 3. Create head and tail int variables to store indices. Head contains the index of the first item where data is retrieved from; and tail contains the index next to the last item where new data is appended at. 4. When reaching the end of the buffer, you re-calculate the index for head or tail, for instance if the capacity of the buffer is 10, when tail pointer reaches 9, the next index for tail is becoming to 0. It overwrites the first element. (Use modulus operator (%) to calculate the new index.) 5. Create methods to perform the data operations such as insert/delete/search item from the buffer.
