To simplify 16m^2/24m^7, you divide both numbers by 8 and subtract the exponents, getting 2/3m^(-5), which is then rewritten with positive exponents as 2/(3m^5).

To simplify the expression 16m^2/24m^7, we need to reduce the fraction by dividing both the numerator and the denominator by their greatest common factor. Additionally, we apply the laws of exponents to simplify the expression further.

First, we observe that 16 and 24 have a common factor of 8. So we divide both by 8:

16 / 8 = 2
24 / 8 = 3

Now our expression looks like this:

2m^2 / 3m^7

Next, we apply the laws of exponents. Since both the numerator and denominator have the base m, we subtract the exponent in the numerator from the exponent in the denominator:

m^2 / m^7 = m^(2-7) = m^(-5)

Combining the reduced coefficients and the exponents, we get:

2/3m^(-5)

To have positive exponents, we can write:

2/(3m^5)

20x^4-39x^3-16x

Make sure to multiply all the terms by each other in the two parentheses

To multiply the given expressions (5x^2-6x+2)(4x^2-3x), we use the distributive property. The resulting expression is 20x^4 - 39x^3 + 18x^2.

To multiply the given expressions (5x^2-6x+2)(4x^2-3x), we can use the distributive property of multiplication. We multiply each term in the first expression by each term in the second expression and then simplify the resulting terms by combining like terms.

First, let's multiply the first terms: 5x^2 * 4x^2 = 20x^4.

Next, let's multiply the outer terms: 5x^2 * -3x = -15x^3.

Then, let's multiply the inner terms: -6x * 4x^2 = -24x^3.

Finally, let's multiply the last terms: -6x * -3x = 18x^2.

Now, let's combine all the resulting terms together: 20x^4 - 15x^3 - 24x^3 + 18x^2 = 20x^4 - 39x^3 + 18x^2.

Answer:

-6

Step-by-step explanation:

"the difference" = subtract.

The difference between -4 and 2 is subtract -4 and 2 together.

-4 - 2 = -6

-6 is your answer.

~

Answer:

The difference is 6

Step-by-step explanation:

The difference means the absolute value, so not what -4-2 is, but how far apart these two are on a number line. We need to take the absolute value of -4-2 so |-4|-|2|=|-6| and absolute value ignores signs so your answer is 6. Let me know if you need more help

A. [tex](\frac{3}{2},3)[/tex]

Step-by-step explanation:

The mapping for  a dilation with center (0,0) scale factor [tex]k[/tex] is

[tex](x,y)\to (kx,ky)[/tex]

Also a reflection over the x-axis has the mapping

[tex](x,y)\to (x,-y)[/tex]

A dilation with center (0,0) scale factor [tex]\frac{3}{2}[/tex] followed by a reflection over the x-axis will yield.

[tex]W(1,-2)\to (\frac{3}{2}\times1,\frac{3}{2}\times -2)\to W'(\frac{3}{2},3)[/tex]

The correct choice is A.

Rectangle WXYZ is dilated with center (0,0) and scale factor 3/2, then reflected over the x-axis to get W"(3/2, 3)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

W has coordinate at W(1, -2). If a dilation of 3/2 is done, the new point is W'(3/2, -3). If it is reflected over the x axis, the point is at W"(3/2, 3)

Answer:

what you trying to say??

Step-by-step explanation:

There are many methods of doing this. This one finds the median; however, instead of halving, you can use quarters instead.

First order the data, ascendingly:

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Find the median:

For an even number of values: The number of values / 2

For an odd number of values: The number of values + 1 / 2

11 is odd.

11 + 1 / 2

12 / 2 = 6

The median is at the 6th position.

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

The median is 20.

Other method:

You don't need this step.

Using the values lower than the median, exclusive, find the median of the lower values;

For an odd number of values: The number of values + 1 / 2

10, 17, 18, 18, 18

5 + 1 / 2 = 6 / 2 = 3

The median of the lower values is at position 3.

This is the lower quartile.

10, 17, 18, 18, 18

Other method:

For an odd number of values: The number of values + 1 / 4

11 + 1 / 4 = 12 / 4 = 3

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Using the values greater than the median, exclusive, find the median:

For an odd number of values: The number of values + 1 / 2

20, 25, 25, 30, 30

5 + 1 / 2 = 6 / 2 = 3

The median of the upper values is at position 3.

20, 25, 25, 30, 30

This is 25.

This is the upper quartile.

Other method:

For an odd number of values: (The number of values + 1 / 4) * 3

(11 + 1 / 4) * 3 = (12 / 4)  * 3 = 3 * 3 = 9

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Your interquartile range is 3 - 25

25 - 3 = 21

Answer:

First figure

Step-by-step explanation:

From given graph we can see that the point (3,0) and (3,1) lie on the given graph.

90 degree rotation counterclockwise around origin:The point (x,y) is rotated 90 degree counterclockwise about origin then the point changed by the rule

[tex](x,y)\rightarrow(-y,x)[/tex]

When the point (x,y) is reflected across x- axis then point is transformed   by the rule

[tex](x,y)\rightarrow (x,-y)[/tex]

Point (3,0) is rotates 90 degree counter clockwise about origin then the point will be (0,3) after rotation.

When the point (0,3) is reflected across x- axis then the point becomes

(0,-3).

The point (3,1) becomes (-1,3) after 90 degree counterclockwise rotation.

After reflection across x- axis, the point becomes (-1,-3)

(0,-3) and (-1,-3) lie in the firs figure.

Hence, it is true.

Answer:

The range of the graph is all real numbers greater than or equal to 0

Step-by-step explanation:

we have

[tex]f(x)=\sqrt{x}[/tex]

we know that

The domain of the function is the interval -------> [0,∞)

All real numbers greater than or equal to zero

The range of the function is the interval -----> [0,∞)

All real numbers greater than or equal to zero

see the attached figure to better understand the problem  

Answer:

The range of the graph is all real numbers greater than or equal to 0.

Step-by-step explanation:

Consider the provided function [tex]f(x)=\sqrt{x}[/tex].

Domain of the function is the set of all possible x values which a function can take.

Range of the function is the set of all output values or the values produced by the function.

Now, consider the provided function.

The value of x can not be a negative number because the square root of negative number is not a real number.

Thus, the domain of the function must be zero or greater than zero.

The graph of the function is shown in figure 1.

From the graph it can be observed that the values produced by that function is all real numbers greater than or equal to 0.

Therefore, the required answer is: The range of the graph is all real numbers greater than or equal to 0.

Answer:

1000 times greater

Step-by-step explanation:

1 gigabyte = 1000000000 bytes

1 mega byte = 1000000 bytes

Therefore;

1 gigabyte = 1000 megabyte

Thus;

The storage capacity of 1 gigabyte is 1000 times greater than a flash drive with a capacity of 1 megabyte

Answer:

"1,000 times greater"

Step-by-step explanation:

We will do the calculation in BYTES.

We want to figure out HOW MANY TIMES GREATER is 1 Gigabyte than 1 Megabyte.

1 Gigabyte (GB) = 10^9 Bytes

1 Megabyte (MB) = 10^6 Bytes

So, how many times is 10^9 is of 10^6? We just need to divide 10^9 by 10^6.

[tex]\frac{10^9}{10^6}=\frac{1000000000}{1000000}=1000[/tex]

So, 1 GB is 1000 times greater than 1 MB.

Answer:

y = (-1)*2^(x + 1)

Step-by-step explanation:

This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.

First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.

So there is an extra power somehow.

Try

y = 2^(x + 1) That looks promising

x = 1

y = 2^(1 + 1)

y = 2^2

y = 4

===============

Try another one

x = 2

y = 2^(2 + 1)

y = 2^3

y = 8

==============

I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.

What about that minus.

y = (-1)*2^(x + 1) should give a minus y value for any term.

They will have $16.75 left.
