**Step-by-step explanation:**

Amir wants to create a 4-digit password for his phone. He wants to choose 4 different numbers between 1 and 5 inclusive. Calculate the total number of 4-digit passwords that Amir can create.

**Answer:**

**Step-by-step explanation:**

Let the digits be:

abcdEach of them include numbers 1 through 5.

For each digit there are 5 options.

Total number of combinations is:

5*5*5*5 = 625
The right answer is 120. Let abcd represent the numbers. The number have to be different meaning no repeats so that would mean:

a has 5 choices of numbers

b had 4

c has 3

d has 2

So the equation would be 5x4x3x2 = 120

a has 5 choices of numbers

b had 4

c has 3

d has 2

So the equation would be 5x4x3x2 = 120

Use the multinomial theorem to compute some polynomial expansions:

(a + b + c)² = a² + b² + c² + 2 (ab + ac + bc)

(a + b + c)³ = a³ + b³ + c³

… … … … … … + 3 (a²b + a²c + ab² + b²c + ac² + bc²)

… … … … … … + 6 abc

(a + b + c)⁴ = a⁴ + b⁴ + c⁴

… … … … … … + 4 (a³b + a³c + ab³ + b³c + ac³ + bc³)

… … … … … … + 6 (a²b² + a²c² + b²c²)

… … … … … … + 12 (a²bc + ab²c + abc²)

Now, given that

**a + b + c = 4**

**a² + b² + c² = 10**

it follows that

**ab + ac + bc** = (4² - 10)/2 = **3**

We use this result to simplify the extra terms in the 3rd-degree expansion.

a²b + a²c + ab² + b²c + ac² + bc²

= a (ab + ac) + b (ab + bc) + c (ac + bc)

= a (ab + ac + bc) + b (ab + ac + bc) + c (ab + ac + bc) - 3abc

… … I underline the terms that are added and subtracted … …

= (a + b + c) (ab + ac + bc) - 3abc

= 4 • 3 - 3abc

= 12 - 3abc

Given that

**a³ + b³ + c³ = 22**

this tells us that

4³ = 22 + 3 (12 - 3abc) + 6abc

4³ = 58 - 3abc

and so

**abc** = (4³ - 58)/(-3) = **-2**

from which it follows that

**a²b + a²c + ab² + b²c + ac² + bc²** = 12 - 3 • (-2) = **18**

Now we similarly simplify the extra terms in the 4th-degree expansion.

a³b + a³c + ab³ + b³c + ac³ + bc³

= a² (ab + ac) + b² (ab + bc) + c² (ac + bc)

= a² (ab + ac + bc) + b² (ab + ac + bc) + c² (ab + ac + bc) - a²bc - ab²c - abc²

= (a² + b² + c²) (ab + ac + bc) - (a²bc + ab²c + abc²)

= 10 • 3 - (a²bc + ab²c + abc²)

which means

4⁴ = a⁴ + b⁴ + c⁴

… … … … … … + 4 (30 - a²bc - ab²c - abc²)

… … … … … … + 6 (a²b² + a²c² + b²c²)

… … … … … … + 12 (a²bc + ab²c + abc²)

reduces to

136 = a⁴ + b⁴ + c⁴

… … … … … … + 6 (a²b² + a²c² + b²c²)

… … … … … … + 8 (a²bc + ab²c + abc²)

Now, we know a + b + c = 4 and abc = -2, so we have

**a²bc + ab²c + abc²** = abc (a + b + c) = -2 • 4 = **-8**

and so

136 = a⁴ + b⁴ + c⁴ + 6 (a²b² + a²c² + b²c²) + 8 • (-8)

200 = a⁴ + b⁴ + c⁴ + 6 (a²b² + a²c² + b²c²)

Finally, we know that ab + ac + bc = 3. Squaring this gives

(ab + ac + bc)² = 3²

a²b² + a²c² + b²c² + 2 (a²bc + ab²c + abc²) = 9

but we also know that a²bc + ab²c + abc² = -8, so

a²b² + a²c² + b²c² + 2 • (-8) = 9

**a²b² + a²c² + b²c² = 25**

Therefore, we end up with

200 = a⁴ + b⁴ + c⁴ + 6 • 25

⇒ **[[[ a⁴ + b⁴ + c⁴ = 50 ]]**

Explain the steps in solving 2.14x-12.18=-576 , and write the solution to the equation.

**Answer:**

x = 274 91/107

**Step-by-step explanation:**

This is called a "two-step linear equation" because it is solved in 2 steps.

**Step 1**. Identify the constant on the same side of the equation as the variable term, and add its opposite to both sides of the equation.

2.14x -12.18 +12.18 = 576 +12.18

2.14x = 588.18

__

**Step 2**. Identify the coefficient of the variable and multiply both sides of the equation by its reciprocal.

2.14x(1/2.14) = 588.18(1/2.14)

x = 274.850467... = 274 91/107 . . . the decimal fraction repeats

**The solution to the equation is x = 274 91/107**.

**Answer:**

x = 274 91/107

The solution to the equation is x = 274 91/107.

Eric has to read a 250-page novel by Friday. With four days left until Friday, he has read 110 pages of the novel. What percentage of the pages does Eric still have to read?

**Answer:**

56% left of the book

**Answer:**

56 %

**Step-by-step explanation: There are two ways to arrive at the answer.**

**1st Way****: 110/250 = 0.44**

**0.44 * 100 = 44%**

**44% is the amount he has read and we are looking for the amount that is left to read.**

**So we know 100% is the maximum percentage.**

**We then subtract 44 from 100 which is 56, So 56 is the answer.**

**2nd Way****: 250-110 = 140**

**140/250=0.56 **

**0.56*100= 56%**

**Hope this helps.**

help i dont know how to do this !!!!!!!!!!!! for brainlist

**Answer:**

We can simplify everything to the power of 2:

[tex]8^{x+2} = 2^{3*(x+2)}=2^{3x+6[/tex]

[tex]16^{x+1} = 2^{4*(x+1)}=2^{4x+4[/tex]

As the two equations are equal to each other and they have common bases, their powers must be equal too. We can come up with this equation:

3x+6=4x+4

solve for x

**x=2**

plug x=2 in and check and you will get 4096=4096

Which function is represented by the graph? f(x) = â’|x â’ 3| 4 f(x) = â’|x 3| 4 f(x) = â’|x â’ 4| 3 f(x) = â’|x 4| 3.

**Functions **are used to represent **graphs**, and vice versa.

The **function **represented by the **graph **is [tex]f(x) =- |x + 4| + 3[/tex]

The graph (see attachment) is an **absolute value graph.**

An **absolute value graph **is represented as:

[tex]f(x) =a |x - h| + k[/tex]

Where

[tex]Vertex = (h,k)[/tex]

The **vertex **is the **minimum **or the **maximum point **on the **graph**.

So, we have:

[tex]Vertex = (-4,3)[/tex]

The **function **becomes

[tex]f(x) =a |x + 4| + 3[/tex]

The **function **also passes through the **point** (-1,0).

So, we have:

[tex]0 =a |-1 + 4| + 3[/tex]

[tex]0 =a |3| + 3[/tex]

Remove the absolute bracket

[tex]0 =3a + 3[/tex]

Subtract 3 from both sides

[tex]3a =- 3[/tex]

Divide both sides by 3

[tex]a =- 1[/tex]

Substitute -1 for (a) in [tex]f(x) =a |x + 4| + 3[/tex]

[tex]f(x) =- |x + 4| + 3[/tex]

Hence, the **function **represented by the **graph **is [tex]f(x) =- |x + 4| + 3[/tex]

Answer plz school is stressful

the answer is 1 month

**Answer:**

1 month.

**Step-by-step explanation:**

When reading a graph, the most important thing is knowing what the axes are. Here, the horizontal x-axis is months, and the vertical y-axis is the number of books read. Those are our 2 variables.

Now, a line on a graph shows the relationship between those 2 variables. At any given point on the line, it'll have an output value of y (books read) for whatever input value of x.

The question gives you the value on the y-axis (books read), so all you need to do is find the value of x that corresponds to that point on the line. I marked that point on the line in the attached image. Look directly below that point on the line, and you can see that 1 month corresponds to 4 books read.
