Final answer:

To rewrite the radical expression 5 square root of x to the 7th power with rational exponents, express it as 5x7/2.

Explanation:

To rewrite the radical expression as an expression with rational exponents, we can use the property that the square root is equivalent to raising to the power of 1/2. Thus, 5√x7 = 5x7/2.

ANSWER

[tex]q = - 7p[/tex]

EXPLANATION

The constant difference of p values is

4-2=2

The constant difference of the 'q' values is

-28--14=-14

The function is of the form:

[tex]q = m(p - p_1) + q_1[/tex]

where

[tex]m = \frac{change \: in \:q }{change \: in \: p} [/tex]

[tex]m = \frac{ - 14}{2} = - 7[/tex]

We plug in the values to get;

[tex]q = - 7(p - 2) + - 14[/tex]

Expand:

[tex]q = - 7p + 14+ - 14[/tex]

Simplify:

[tex]q = - 7p[/tex]

Answer:

A.ones

Step-by-step explanation:

Depending on the state and country, cars can have 1 or 2 license plates on them.  The one mandatory is in the back.  In some places, the cars also have a license plate in the front of the car.

So, since the answer is either 1 or 2, the range for that answer is under 10... so it's a single digit... making it a measure in ones.

The number of tires on a car is also measured in ones.  

Answer: 5.5

Step-by-step explanation: Converting This To A Decimal Would Be 5.5

to make it into a decimal you would convert the fraction into a decimal which would be .5 then you would take the 5 and make it 5.5

For this case we have the following mixed number:

[tex]5 \frac {1} {2}[/tex]

We move to fraction, then we have to:

[tex]5 \frac {1} {2} = \frac {5 * 2 + 1 * 1} {2} = \frac {10 + 1} {2} = \frac {11} {2}[/tex]

Dividing we have to:

[tex]\frac {11} {2} = 5.5[/tex]

Answer:

[tex]5 \frac {1} {2} = 5.5[/tex]

Answer:

First Option

Step-by-step explanation:

A relation is an association or correspondence between two sets, where each element of the Domain Set corresponds to at least one element of the Range set.

The function definition says that:

A relation is a function if and only if, for each input value x, there is only one output value y. In other words, a relation is a function if each value of the Domain set has only one value associated with the Range set.

Therefore, not all relationships are functions, but all functions are relations.

The correct option is the first

Answer:

Observe the attached image

Step-by-step explanation:

If we have a function f(x), the inverse of the function denoted [tex]f ^{- 1} (x)[/tex] will have as domain the range of f(x) and its rank will be the domain of the function f(x) this means that if f(x) is given by the following ordered pairs:

x: 0, 4, 9, 10; and: 3, 2, 7, -1

(0, 3) (4, 2) (9, 7) (10, -1)

Then [tex]f ^{- 1}(x)[/tex] will have the following ordered pairs

x: 3, 2, 7, -1 and: 0, 4, 9, 10

(3, 0) (2, 4) (7, 9) (-1, 10)

Observe the attached image

The blue dots are the ordered pairs of the relationship

The red open dots are the ordered pairs of the inverse of the relationship

Answer:

11,232,000

Step-by-step explanation:

The key to this problem is knowing "repetition is NOT ALLOWED".

For the first 3 letters slot:

For the 1st slot, we can pick any of the 26 alphabets

For the 2nd slot, we can pick any of the 25 remaining alphabets (since 1 is already taken)

For the 3rd slot, we can pick any of the 24 remaining letters (since 2 is already taken)

For the three digits slot:

For the 1st slot, we can pick any one of the 10 digits

For the 2nd slot, we can pick any one of the 9 digits left, since 1 is taken already

For the 3rd slot, we can pick any one of the 8 digits left, since 2 is already taken

The number of license plates, thus, would be all of these multiplied together:

26 * 25 * 24 * 10 * 9 * 8 = 11,232,000

Answer: No association

Answer:

-8x + 6

Step-by-step explanation:

Subtract "5x-2" from "-3x + 4". Set the equation.

(-3x + 4) - (5x - 2) = Answer (A)

First, distribute -1 to all terms within the second parenthesis.

-3x + 4 - 5x + 2 = A

A = -5x - 3x + 4 + 2

Simplify. Combine like terms (terms with the same amount of variables).

A = (-5x - 3x) + (4 + 2)

A = -8x + 6

-8x + 6 is your answer, or the first answer choice.

Answer:

The Median is 9

Step-by-step explanation:

To calculate the median of a data set the first step is to sort the data from least to greatest

4,11,6,9,23,34,6,9

4, 6, 6, 9, 9, 11, 23, 34

The second step is to locate the central value. If the total amount of data is an even number then locate the two central data and the median will be the average of both. In this case we have 8 data. Then the central values will be the data number 4 and the data number 5

4, 6, 6,   [9, 9],   11, 23, 34

[tex]Median = \frac{9+9}{2}=9[/tex]

Answer:

312 m

Step-by-step explanation:

Write and solve an equation of ratios:

 7       273 m

----- = ------------

 8            x

Then 7x = 8(273 m) = 2184 m

and x = 2184 m / 7 = 312 m

The second length in the given ratio of 7:8, when the first length is 273m, is calculated to be 312m.

The given question is about ratios, particularly the ratio between two lengths, where one of them is given as 273 meters and the ratio is 7:8. The ratio tells us that for every 7 units of the first length, there are 8 units of the second length. To calculate the second length, first find the value of one ratio unit by dividing the given length by its ratio (273m / 7), then multiply your result by 8.

Steps:
1. 273m / 7 = 39m (This is one ratio unit)
2. 39m * 8 = 312m (This is the second length).

Therefore, the length of the second line is 312 m.

For this case we must find the value of the variable "x" of the following equation:

[tex]\frac {2} {3} (x + 7) = 10[/tex]

We multiply by 3 on both sides of the equation:

[tex]2 (x + 7) = 30[/tex]

We divide between 2 on both sides of the equation:

[tex](x + 7) = 15\\x + 7 = 15[/tex]

We subtract 7 on both sides of the equation:

[tex]x = 8[/tex]

Answer:

Option B

Answer:

Z is also 116*

Step-by-step explanation:

The reason for them being the same is because of something called alternating angles. This process allows you to find two angle measurements by just finding one.

we know line P is y = 3x.

parallel lines have the same slope but different y-intercept, where the graph touches the y-axis.  So then parallel lines is the same equation but shifted some either upwards or downwards or sideways.

so then line Q must be the same as P, y = 3x + "some change", well, we notice that the perpendicular distance from each other is 3 units, so then, the y-intercept of P is at (0, 0), thus the y-intercept of Q must be 3 units downwards, at (0, -3), since Q is shifted downwards, thus Q is y = 3x - 3.

The answer is $41.44.

You take $895× 4.63%= $41.4385.

Answer:

a) 2x² + 14x + 24 = 0

Step-by-step explanation:

a)

2x² + 14x + 24 = 0

2(x + 4) (x + 3) = 0

x = -4 or x = -3

b)

x² - 6x + 5 = 0

(x - 1)(x - 5) = 0

x = 1 or x = 5

c)

3x² + 30x + 48 = 0

3 (x + 8) (x + 2) = 0

x = -8 or x = -2

d)

-3x² - 12x + 15 = 0

-3 (x + 5) (x - 1) = 0

x = -5 or x = 1

Final answer:

The equation which yields the solutions x=-3 and x=-4 is a. 2x² + 14x + 24 = 0.

Explanation:

To find which equation yields the solutions x=-3 and x=-4, we need to determine which equation, when factored, gives these roots. If an equation has roots x = -3 and x = -4, then it can be written in factorized form as:

(x + 3)(x + 4) = 0

Expanding this, we get:

x² + 4x + 3x + 12 = 0

x² + 7x + 12 = 0

Looking at the given options, we notice that none of them exactly match this equation. However, if we multiply our equation by 2, we get:

2x² + 14x + 24 = 0

This matches option (a). Therefore, the correct equation is:

2x² + 14x + 24 = 0

Answer:

D

Step-by-step explanation:

1. Use property of exponents:

[tex](a^b)^c=a^b\cdot ... \cdot a^b\ [\text{ take }c \text{ times } a^b][/tex]

Hence

[tex](7^{\frac{1}{3}})^3=7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}[/tex]

2. Use multiplication property of exponents:

[tex]a^b\cdot a^c=a^{b+c}[/tex]

Thus,

[tex]7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}=7^{\frac{1}{3}+\frac{1}{3}+\frac{1}{3}}[/tex]

3. Since

[tex]\frac{1}{3}+\frac{1}{3}+\frac{1}{3}=\frac{3}{3}=1,[/tex]

we have that

[tex]7^{\frac{1}{3}+\frac{1}{3}+\frac{1}{3}}=7^1=7[/tex]

____________________________________________________

Answer:

Your answer would be a 9.5% increase.

____________________________________________________

Step-by-step explanation:

In order to find the answer to your question, we would need to get the amount it's changing by, divide it by it's original, and multiply it by 100.

Your equation should look like this:

[tex]Change/Original * 100[/tex]

Important information in the question:

105 pounds

115 pounds (increase in amount of food that bear eats)

With the information above,we can plug those numbers into our equation.

Since we need to find the change, we would subtract 115 and 105 to get 10. 10 is our change in this scenario.

Our original started at 105, so that'll be our original in our equation.

When you plug in the information, your equation should look like this:

[tex]10/105*100[/tex]

Now you solve:

[tex]10/105*100\\\\0.0952 * 100\\\\=9.523[/tex]

We have to round to the nearest tenth, and the tenth place is the number right after the decimal place.

Since 2 is not a big enough number to round the 5, we would keep the number as 5. Therefore, your answer would be 9.5

Your FINAL answer would be 9.5%

1÷3=13.

Step-by-step explanation:

To find the reciprocal of any number simply take 1 and divide it by that number, so the reciprocal of 3 is 1÷3=1/3. We can check that this is the multiplicative inverse of 3 by multiplying those two numbers together and seeing if we get 1: so 3×1/3=3×1/3=1. Where it says =3 you put a line through that 3.

Answer:

6pi or about 18.8 units

Step-by-step explanation:

See attached file

To calculate the arc length of a circle with a 120° central angle and a 9-unit radius, multiply the fraction of the circle (1/3) by the circle's circumference (2πr) to find the arc length is 6π units.

To find the length of an arc with a central angle of 120° in a circle with a radius of 9, we use the formula for arc length. The arc length (As) is proportional to the angle of rotation, which in this case is 120° or θ = 120° ÷ 360°.

The circumference (C) of a circle is given by the formula 2πr, where r is the radius. For a full revolution (360°), the arc length is equal to the circumference. For an angle θ, the arc length is given by:

As = (θ/360°) × 2πr

Using the radius r = 9 and θ = 120°, we calculate:

As = (120°/360°) × 2π(9)

As = (1/3) × 18π

As = 6π

The arc length is 6π units, which is slightly less than 19, as π is approximately 3.14159.
