Who knows what the middle part is asking

ANSWER

all real numbers

EXPLANATION

The given absolute value function is

[tex]f(x) = |x + 2| [/tex]

This function is obtained by shifting the graph of

[tex]y = |x| [/tex]

to the left by 2 units.

Since the domain of the parent function is all real numbers, the domain of the transformed function is also all real numbers because the shifting the parent function horizontally or vertically does not affect the domain.

Answer:

Hi there!

The answer is: 2 and -2

Step-by-step explanation:

Case 1: An absolute value of positive number will still be a positive number

so absolute value of 2 is 2

Case 2: An absolute value of negative number will be positive number so absolute value of -2 is 2

Answer:

The Absolute Value of Both 2 and -2 is 2

Step-by-step explanation:

An Absolute Value (abs) is the non-negative value of that number or to put it in other words, it is the amount of space between that number and 0 on a number line. Every Absolute Value other than 0 has two values (a positive and a negative) since the Absolute Value is always a positive. For Example,

abs(-2) = 2 = abs(2) ......The Absolute Value of both 2 and -2 is 2

abs(-75) = 75 = abs(75) .... The Absolute Value of both 75 and -75 is 75

Answer:

B

Step-by-step explanation:

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]

Given m = - [tex]\frac{5}{6}[/tex], then

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{-\frac{5}{6} }[/tex] = [tex]\frac{6}{5}[/tex]

Since m > 0 then lines LM and No are the 2 possible lines

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = L(- 5, - 3) and (x₂, y₂ ) = M(0, 3)

m = [tex]\frac{3+3}{0+5}[/tex] = [tex]\frac{6}{5}[/tex]

Hence the required line is LM

Step-by-step explanation:

Answer:

1. P(5 U 6) =2/3

2. P(2 U 5 U 6) = 5/6

3. P(1 U 2) = 1/3

4. P(4) = 0

Step-by-step explanation:

As the number cube has 6 sides,

So,

Total outcomes = {1,2,5,5,6,6}

n(S) = 6

Now,

1. P(5U6) = P(5) + P(6)

P(5)=2/6=1/3

P(6)=2/6=1/3

P(5U6)= 1/3 + 1/3 = 2/3

2. P(2 U 5 U 6) = P(2) + P(5) + P(6)

P(2)=1/6

P(5)=2/6

P(6)=2/6

P(2 U 5 U 6) = 1/6 + 2/6 + 2/6

= 5/6

3. P(1 U 2) = P(1) + P(2)

P(1) = 1/6

P(2)= 1/6

P(1 U 2) = 1/6 + 1/6

= 2/6 = 1/3

4. P(4) = 0

As 4 is not in the outcomes, it's probability will be zero ..

Answer:

5, − one third , one half

Step-by-step explanation:

If the number 'n' is a zero of f(x), then f(n)=0.

We could solve this problem by factorizing the polynomial, but the quickest way is by plugging the options into the equation.

We know that f(x) = 6x3 − 31x2 + 4x + 5.

Then:

Then, the correct option is: 5, − one third , one half.

Finally, the factorized form is: (x−5)(2x−1)(3x+1). If you expand it, you will get the original polynomial.

Answer:  The correct option is

(B) 5, − one third , one half.

Step-by-step explanation:  We are given to select the correct option that represents the zeroes of the following cubic function :

[tex]f(x)=6x^3-31x^2+4x+5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

if for any number a, the function f(x) is zero at x =a , then x = a is a zero of the function f(x).

We have, for the given function, at x = 5,

[tex]f(5)\\\\=6\times5^3-31\times5^2+4\times5+5\\\\=125\times6-31\times25+20+5\\\\=750-775+25\\\\=0[/tex]

So, x = 5 is a zero of the function f(x).

Now, we have

[tex]f(x)\\\\\=6x^3-31x^2+4x+5\\\\=6x^2(x-5)-x(x-5)-(x-5)\\\\=(x-5)(6x^2-x-1)\\\\=(x-5)(6x^2-3x+2x-1)\\\\=(x-5)(3x(2x-1)+1(2x-1))\\\\=(x-5)(3x+1)(2x-1)[/tex]

The zeroes of f(x) are given by

[tex]f(x)=0\\\\\Rightarrow (x-5)(3x+1)(2x-1)=0\\\\\Rightarrow x-5=0,~~3x+1=0,~~2x-1=0\\\\\Rightarrow x=5,-\dfrac{1}{3},\dfrac{1}{2}.[/tex]

Thus, the zeroes of f(x) are 5, -one-third, one half.

Option (B) is CORRECT.

Answer:

ED = 5π/6

Step-by-step explanation:

First convert angles into radians by using formula 1° = π/180 rad

So, 50° becomes 5π/18.

Now using formula,

angle = length of arc / radius of circle

we get,

5π/18 = length of arc / 3

Hence , length of arc = 5π/6

Answer:

ED ≈ 2.62 in

Step-by-step explanation:

The length of the arc ED is calculated as

ED = circumference × fraction of circle

     = 2πr × [tex]\frac{50}{360}[/tex]

     = 2π × 3 × [tex]\frac{5}{36}[/tex]

     = 6π × [tex]\frac{5}{36}[/tex]

     = [tex]\frac{5\pi }{6}[/tex] ≈ 2.62 in ( to 2 dec. places )

Answer:

[tex]\large\boxed{x=-\dfrac{1}{11}}[/tex]

Step-by-step explanation:

[tex]34x+5-12x=3\qquad\text{subtraxct 5 from both sides}\\\\34x-12x=3-5\\\\22x=-2\qquad\text{divide both sides by 22}\\\\x=\dfrac{-2}{22}\\\\x=-\dfrac{2:2}{22:2}\\\\x=-\dfrac{1}{11}[/tex]

To solve the equation 34x+5−12x=3, we combine like terms to get 22x+5=3, then isolate x to find that x=-1/11.

The student's question, 34x+5−12x=3, presents a linear equation where we need to find the value of x.

To solve for x, we shall first consolidate like terms on the left side of the equation.

We have:

34x - 12x + 5 = 3

22x + 5 = 3

22x = 3 - 5

22x = -2

x = -2/22

x = -1/11

The value of x in this equation is -1/11.

Answer:

B. 24

Step-by-step explanation:

it takes 60 minutes for one and 40 for another. since you don't know the time. the denominator is going to be x. The equation to solve this problem will be x/60 + x/40 = 1. Since you're adding, you want to have the same denominator. ( i chose to do 120) this will change the problem to 2x/120 + 3x/120 = 1. which will simplify to 5x/120=1. Multiply each side by 120 to get 5x=120 and divide each side by 5 to get x=24.

Answer:

a) The equation to find the elevation of Mt. Wilson is [tex]28,784.31=x+11,510.21[/tex]  

b) The elevation of Mt. Wilson is [tex]17,274.10\ ft[/tex]  

Step-by-step explanation:

Let

x ----> represent the elevation of Mt. Wilson

y ----> represent the elevation of Snow Crest

we know that

[tex]y=x+11,510.21[/tex] ----> equation A

we have

[tex]y=28,784.31\ ft[/tex]

Substitute the value of y in equation A and solve for x

[tex]28,784.31=x+11,510.21[/tex]  

[tex]x=28,784.31-11,510.21[/tex]

[tex]x=17,274.10\ ft[/tex]  

The elevation of Mt. Wilson is 17,274.1 feet.

To find the elevation of Mt. Wilson, you can set up an equation based on the information given. You're told that Snow Crest is 11,510.21 feet higher than Mt. Wilson, so you can write the equation as follows:

Elevation of Snow Crest = Elevation of Mt. Wilson + 11,510.21

Now, you can plug in the elevations you have:

Elevation of Snow Crest = 28,784.31 feet

Elevation of Mt. Wilson = x (since you're using x to represent the elevation of Mt. Wilson)

So, the equation becomes:

28,784.31 = x + 11,510.21

Now, you need to solve for x, which represents the elevation of Mt. Wilson. To isolate x, you can subtract 11,510.21 from both sides of the equation:

x = 28,784.31 - 11,510.21

x = 17,274.1

So, the elevation of Mt. Wilson is 17,274.1 feet.

Answer:

D. y - 5 =3(x + 1)

Step-by-step explanation:

y = -1/3x -6

The slope is -1/3

Take the negative reciprocal to find the slope of the line that is perpendicular

- (-3) = 3

The slope would be 3

We have the slope and a point

Using point slope form

y-y1 = m(x-x21)

y-5 = 3(x--1)

y-5 = 3(x+1)

Answer:

D. y - 5 =3(x + 1)

Step-by-step explanation:

Given equation of line:

[tex]y = -\frac{1}{3}x-6[/tex]

Comparing it with the standard form of equation of line

y=mx+b

m = -1/3

Let m1 be the slope of line perpendicular to the given line.

We know that the product of slopes of two perpendicular lines is -1.

[tex]m*m_1 = -1\\-\frac{1}{3} * m_1 = -1\\ m_1 = -1 * -\frac{3}{1}\\ m_1 = 3[/tex]

The equation of line in point slope form is:

[tex]y-y_1 = m(x-x_1)[/tex]

where x_1 and y_1 is the point from which the line passes.

So, putting the values of slope and point,

[tex]y-5 = 3[x-(-1)]\\y-5=3(x+1)[/tex]

Your answer is B.

You want the formula for conditional probability.

P(X | B) = (X and Y)/P(Y)

Final answer:

P(X | Y) = P(X and Y) / P(Y).

Explanation:

The formula P(X | Y) represents the probability of event X occurring given that event Y has already occurred.

This concept is often used in the context of conditional probability, which differs from the calculation of independent events where the probability of both events X and Y occurring is simply the product of their individual probabilities, denoted as P(X) · P(Y).

When events are not independent, to find the conditional probability P(X | Y), you would typically use the formula

P(X | Y) = P(X and Y) / P(Y),

where

P(X and Y) is the joint probability of events X and Y occurring together, and

P(Y) is the probability of event Y occurring.

Answer:

(0,0) (-6,0), (-2,0)

Step-by-step explanation:

Answer:

The correct choice is A. (-6,0), (-2,0) and (0,0).

Step-by-step explanation:

Consider the provided information:

The provided function f(x) is an even function and has 5 x-intercept.

Therefore,

f(x) = f(-x)

Thus, there will be positive and negative pairs of zeros.

As it is given that the x intercept is at (6,0). Therefore, the another x intercept will be on (-6,0).

If there are an odd number of intercepts and function is even then, (0,0) will be the x intercept because of its own negation.

The only choice with (-6,0) and (0,0) is A.

Therefore, the correct choice is A. (-6,0), (-2,0) and (0,0).

Answer:

Option B and C  are correct.

Step-by-step explanation:

We need to find the pattern of the values in the table and find the values of a and b.

6³ = 216

216/6 = 36

6² = 36

36/6 = 6

6¹ = 6

6/6 = 1

6⁰ = 1

1/6 = 1/6

6⁻¹ = 1/6

1/6*1/6 = 1/36

6⁻² = 1/36

So, value of a = 1/6

and value of b = 1/36

And we have seen as the exponent is decreasing, each previous value is divided by 6.

So, Option B and C  are correct.

Answer:  The correct options are

(B) the value of b is [tex]\dfrac{1}{36}.[/tex]

(C) As the value of the exponent decreases, each previous value is divided by 6.

Step-by-step explanation:  We are given that Tori examined the pattern of exponents in the following table :

[tex]\textup{power of 6}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\textup{value}\\\\6^3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~216\\\\6^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~36\\\\6^1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~6\\\\6^0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~1\\\\6^{-1}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~a\\\\6^{-2}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~b[/tex]

We are to select the true statements based on the above pattern.

We will be using the following property of exponents :

[tex]x^{-y}=\dfrac{1}{x^y}.[/tex]

Therefore, we get

[tex]a=6^{-1}=\dfrac{1}{6^1}=\dfrac{1}{6}.[/tex]

and

[tex]b=6^{-2}=\dfrac{1}{6^2}=\dfrac{1}{36}.[/tex]

Also, the value of the exponent is decreasing and we see that

[tex]\dfrac{216}{36}=\dfrac{36}{6}=\dfrac{6}{1}=\dfrac{1}{\frac{1}{6}}=\dfrac{\frac{1}{6}}{\frac{1}{36}}=6.[/tex]

So, each previous value is divided by 6.

Thus, the correct options are

(B) the value of b is [tex]\dfrac{1}{36}.[/tex]

(C) As the value of the exponent decreases, each previous value is divided by 6.

Step-by-step explanation:

To solve the logarithmic equation with different bases, one must recognize the importance of base conversion and utilize logarithmic properties to guide conversion or comparison, not just directly equate the logarithmic arguments, which was a misunderstanding.

To solve the equation log_4(x + 3) = log_2(2 + x), we need a system that represents this equation effectively by considering logarithmic properties and base conversion.

Steps for Solving the Equation

Recognize that both sides of the equation are logarithms, which implies their arguments must be equal if their outputs are equal. Thus, it means x + 3 = 2 + x.

This simplification does not directly solve our original equation due to the different bases of the logarithms. We utilize the property that allows us to convert between bases: log_a(b) = log_c(b) / log_c(a), specifically focusing on changing base 4 logarithm to base 2.

We apply this to convert log_4(x + 3) to a base 2 logarithm, yielding a new equation: log_2(x + 3)/log_2(4) = log_2(2 + x).

Since log_2(4) = 2, the equation simplifies to 0.5 * log_2(x + 3) = log_2(2 + x).

This step reveals that the initial transformation inadvertently simplified through a direct comparison, which doesn't correctly express the conversion between bases or the nature of the original problem.

To correctly translate the given logarithmic equation into a system of equations, acknowledge that the original task was misunderstood in Step 1, as it did not account for the different log bases and their properties.

Instead, consider equations that capture the essence of converting bases or applying logarithmic identities to derive a solution.

A more accurate representation would involve recognizing the base conversion and understanding that without a direct means of converting or equating the logarithms due to their different bases and the variables involved, it does not straightforwardly lead to a solvable system without further information or manipulation that squarely addresses the base disparity.
