What is the domain of the function

y=In(x+2)​

Answer:

The point is (3.5 , 7.25)

Step-by-step explanation:

∵ A = (2 , 8) and B = (8 , 5)

∵ Let point P divides AB into a ratio 1:3

∵ [tex]x=\frac{m_{2}x_{1}+m_{1}x_{2}}{m_{1}+m_{2}}[/tex]

∵ [tex]y=\frac{m_{2}y_{1}+m_{1}y_{2}}{m_{1}+m_{2}}[/tex]

∴ x-coordinate of P = (2)(3) + (8)(1)/3 + 1 = (6 + 8)/4 = 3.5

∴ y-coordinate of P = (8)(3) + (5)(1)/1 + 3 = (24 + 5)/4 = 7.25

∴ P = (3.5 , 7.25)

The point that partitions the directed line segment AB into a 1:3 ratio is P(3.5, 7.25), calculated using the section formula.

To find the point that partitions the directed line segment AB into a 1:3 ratio, we use the section formula. The section formula for a point P(x, y) that divides the line segment connecting A(2, 8) to B(8, 5) in the ratio m:n is given by:

x = ([tex]m \times x2 + n \times x1[/tex]) / (m + n)

y = ([tex]m \times y2 + n \times y1[/tex]) / (m + n)

Given the ratio 1:3, the coordinates for point P can be calculated as follows:

x = ([tex]1 \times 8 + 3 \times 2[/tex]) / (1 + 3) = (8 + 6) / 4 = 14 / 4 = 3.5

y = ([tex]1 \times 5 + 3 \times 8[/tex]) / (1 + 3) = (5 + 24) / 4 = 29 / 4 = 7.25

Therefore, the point that divides the line segment AB in a 1:3 ratio is P(3.5, 7.25).

Answer:

d. X^2 - 49

Step-by-step explanation:

I will assume that the question marks are minus signs.

Let's remember what does "difference of two squares" means:

The difference of two squares is a number multiplied by itself subtracted from another number multiplied by itself (the number multiplied by itself is called squared number).

In our options, the first number is always a squared number because it's X^2 = X * X.

We just have to analyze the second number.  

First, let's notice that a. and c. can't be correct because we have a sum instead of a subtract.

We have left 14 and 49 to analyze:

14 = 7*2 (it's not a squared number)

49 = 7*7 (it's a squared number)

The answer is X*X - 7*7 = X^2 - 49

  the picture is correct

Step-by-step explanation:

Each square on the original shape becomes 2 squares on the enlarged shape, just as you have drawn.

Enlarging shapes using a scale factor of 1:2 involves multiplying each side length by 2.

To enlarge a shape using a scale factor of 1:2, each side length of the shape needs to be multiplied by 2. For example, if a square has sides of length 4 cm, when enlarged with a scale factor of 1:2, each side will become 8 cm. This is because multiplying 4 by 2 gives us 8.

Similarly, if a triangle has side lengths of 6 cm, 8 cm, and 10 cm, when enlarged with a scale factor of 1:2, the new side lengths will be 12 cm, 16 cm, and 20 cm. Each side length is multiplied by 2

Remember, the scale factor tells you how many times larger the new shape will be compared to the original shape. In this case, every length of the shape is being doubled.

the correct answer choice is B.

The equation of the graph for the function f(x) = 7x after being shifted 6 units to the right is g(x) = 7(x - 6), which is option B.

When a graph of the form f(x) = mx is shifted horizontally, this is represented in the equation by manipulating the x variable within the function. A shift to the right by 6 units results in the input value being decreased by 6 before it is multiplied by the slope (in this case, 7). Therefore, the new equation reflecting a horizontal shift to the right is g(x) = 7(x - 6), which corresponds to option B.

Step-by-step explanation:

Given in the question an expression

ln[tex]\frac{1}{\sqrt{e^3} }[/tex]

First apply logarithm divide rule

[tex]ln\frac{1}{\sqrt{e^3} }[/tex] = ln1 - ln√e³

ln(1) = 0

so

ln1 - ln√e³ = 0 - ln√e³

-ln√e³ = -ln(e³)^1/2

The rate of change of pay with respect to hours is $15.75 per hour.

The rate of the change by calculated by dividing the total pay by the corresponding number of hours.

The amount of money he earns is $63 in 4 hours.

Rate of change of pay = $110.25 - $63/7 - 4 per hour

= $15.75 per hour

This is consistent with the other values in the given table.

Rate of change of pay = $141.75 - $110.25/9 - 7 per hour

= $15.75 per hour

Answer:

B. False. Within stratified​ samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population.

Step-by-step explanation:

In a stratified sample, each stratum should be proportional to that category of the population.  This means that each stratum would potentially have a different number of elements in it.

The statement is false. Stratified sampling does not require the number of individuals to be equal within each stratum.

The statement 'When obtaining a stratified​ sample, the number of individuals included within each stratum must be equal' is False. When using stratified sampling, the number of individuals included within each stratum does not have to be equal. In stratified sampling, the population is divided into different groups or strata based on certain characteristics, and then individuals are randomly selected from each stratum. The number of individuals selected from each stratum is often proportional to the size of the stratum in the population, which makes the sample more representative.

5 x 11 = 55

55 = 55

55 > 54

1 < 55

3 x 2 < 55

To compare numbers to 55, choose numbers less than, greater than, or equal to 55 and use the appropriate comparison operator. Examples include 50 < 55 (less than), 55 = 55 (equal to), and 60 > 55 (greater than).

To compare numbers with 55 using the comparison operators >, <, and =, we must choose numbers that are either greater than, less than, or equal to 55. For example:

When you are comparing numbers, always remember that a number is greater than another if it represents a larger quantity, and it is less than another if it represents a smaller quantity. The equal sign is used when the quantities are identical.

Answer:

$13.04 is the original price of the shirt

Step-by-step explanation:

As sales tax is 8% we will find the price of the shirt

11.34 * 8/100 = 0.91

11.34-0.91= 10.43

so, $10.43 is the price of the shirt after discount and excluding sales tax.

The original price of the shirt is:

10.43 * 25 /100 = 2.60

ANSWER

12

EXPLANATION

Two expressions for the angles in terms of x are given,

The first one is (10x-20)°

The second one is (6x+8)°

The two angles are angles on a straight line.

The sum of angles on a straight line is 180°.

This implies that,

[tex](10x - 20) \degree + (6x + 8) \degree = 180 \degree[/tex]

Group similar terms,

[tex]10x + 6x= 180 + 20 - 8[/tex]

Combine like terms:

[tex]16x=192[/tex]

[tex]x = \frac{192}{16} = 12[/tex]

Therefore the value of x is 12

The value of x is 12°

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Given

The angles are (10x - 20)° and (6x + 8)°.

The value of x.

The angles are (10x - 20)° and (6x + 8)°.

We know that the sum of the angles of the line is 180°. then

(10x - 20)° + (6x + 8)° = 180°

Then simplify the equation, we have

10x - 20 + 6x + 8 = 180

              16x - 12 = 180

                     16x = 180 + 12

                     16x = 192

                         x = 12°

Thus, the value of x is 12°.

Step-by-step explanation:

1,8272 --- 8,000

17,282 --- 80

8,000÷80=100 times greater

Final answer:

The value of 8 in the number 18,272 (8,000) is 100 times greater than its value in the number 17,282 (80).

Explanation:

The question is asking how many times the value of 8 in 18,272 is greater than the value of 8 in 17,282.

In the number 18,272, the 8 is in the thousands place, making it have a value of 8,000. In the number 17,282, the 8 is in the tens place, giving it a value of 80.

To determine how many times greater the value of 8 is in the first number compared to the second, divide the larger value by the smaller value: 8,000 ÷ 80 = 100.

Therefore, the value of 8 in 18,272 is 100 times greater than in 17,282.
