The domain restrictions for (f/g)(x) are (c) x = 0, 6

From the question, we have the following parameters that can be used in our computation:

f(x) = x² - 5x - 6

g(x) = x² - 6x

The composite function (f/g)(x) is calculated as

(f/g)(x) = f(x)/g(x)

substitute the known values in the above equation, so, we have the following representation

(f/g)(x) = (x² - 5x - 6 )/(x² - 6x)

For the domain restriction, we have

x² - 6x = 0

When solved, we have

x =  6 or x = 0

Hence, the domain restrictions for (f/g)(x) are (c) x = 0, 6

Question

Given f(x) = x² - 5x - 6 and g(x) = x² - 6x, what are the domain restrictions

for (f/g)(x)?

A) x = +6

B) x = 0

C) x = 0,6

D) x = -2,6

A) the total number of boxes in the bottom 2 layers is 100 + 80 = 180 boxes. B) Number of boxes in each layer = W(n) * D C) the total number of boxes needed to make up the 4 layers is 280 boxes.

A) To determine the number of boxes in the bottom 2 layers:

The bottom layer has a width of 20 boxes and is 5 boxes deep.

The second layer has a width of 16 boxes and is also 5 boxes deep.

Number of boxes in the bottom layer = 20 boxes wide * 5 boxes deep = 100 boxes

Number of boxes in the second layer = 16 boxes wide * 5 boxes deep = 80 boxes

Therefore, the total number of boxes in the bottom 2 layers is 100 + 80 = 180 boxes.

B) To develop a formula to calculate the number of boxes in n layers:

Let's denote the width of each layer as W and the depth of each layer as D.

The width of each layer follows the pattern: 20, 16, 12, 8.

We can observe that the width decreases by 4 units for each consecutive layer.

The formula to calculate the width of the nth layer can be written as:

W(n) = 20 - 4 * (n - 1)

Since each layer has a depth of 5 boxes, the number of boxes in each layer can be calculated as:

Number of boxes in each layer = W(n) * D

C) To use the formula from part B to solve for the total number of boxes needed to make up the 4 layers:

We want to calculate the total number of boxes in 4 layers.

Number of boxes in 4 layers = Number of boxes in the first layer + Number of boxes in the second layer + Number of boxes in the third layer + Number of boxes in the fourth layer

= W(1) * D + W(2) * D + W(3) * D + W(4) * D

= (20 - 4 * 0) * 5 + (20 - 4 * 1) * 5 + (20 - 4 * 2) * 5 + (20 - 4 * 3) * 5

= 20 * 5 + 16 * 5 + 12 * 5 + 8 * 5

Simplifying the expression, we get:

Number of boxes in 4 layers = 100 + 80 + 60 + 40 = 280 boxes

Therefore, the total number of boxes needed to make up the 4 layers is 280 boxes.

Answer:

113.1in^2 (round to 1dp)

Step-by-step explanation:

to calculate the area of a circle, you use the formula π\(r^{2}\) where r is the radius which in this case is 6 and the square of 6 is 36 so its 36π

which equals 113.0973355in^2 and 113.1in^2 if you round it to 1 decimal place

The formula for the area of a circle is:

Area = π x (radius)^2

where π (pi) is a mathematical constant approximately equal to 3.14159, and the radius is half of the diameter.

Given that the diameter of the circle is 12 in, we can find the radius by dividing the diameter by 2:

radius = diameter / 2 = 12 in / 2 = 6 in

Now we can substitute this value into the formula for the area:

Area = π x (radius)^2 = π x (6 in)^2

Using a calculator to approximate π as 3.14159, we get:

Area ≈ 3.14159 x (6 in)^2 ≈ 113.1 in^2

Therefore, the area of the circle with a diameter of 12 in is approximately 113.1 square inches.

The probability that the mean of a sample of 40 families will be between 17.1 and 18.1 pounds is given as follows:

0.5874 = 58.74%.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The parameters for this problem are given as follows:

\(\mu = 17.2, \sigma = 2.5, n = 40, s = \frac{2.5}{\sqrt{40}} = 0.3953\)

The probability that the mean of a sample of 40 families will be between 17.1 and 18.1 pounds is the p-value of Z when X = 18.1 subtracted by the p-value of Z when X = 17.1, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem:

\(Z = \frac{X - \mu}{s}\)

Z = (18.1 - 17.2)/0.3953

Z = 2.28

Z = 2.28 has a p-value of 0.9887.

Z = (17.1 - 17.2)/0.3953

Z = -0.25

Z = -0.25 has a p-value of 0.4013.

Hence:

0.9887 - 0.4013 = 0.5874 = 58.74%.

Answer: andres is 5 years old pls banned him he called e a mean word like the N word

Step-by-step explanation:

Answer:

Solution : Option D

Step-by-step explanation:

Let's start by listing two cases made possible when r is positive, in ( r, θ ). Remember that in polar coordinates a point is expressed in an ordered pair, where r is the distance from the pole (in this case 9, as it lies on the 9th circle) and theta is the directed angle from the positive x - axis.

( 9, θ ) here theta will be the angle to the terminal side with respect to the positive x - axis. This angle will be 60 degrees more than 90, or 90 + 60 = 150 degrees

( 9, θ ) and here theta will be the remaining degrees, or 360 - 150 = 210 degrees. Right away your solution will be (9, 210°)

Based on the given information, we have a square pyramid with points M and N being the midpoints of the edges of one face. and forms a parallelogram. Option D

Since the base of the pyramid is a square, the cross section will consist of a square shape. Additionally, since the slice is made through the midpoints of the edges of the face, the resulting cross section will have parallel sides.

Considering these characteristics, we can conclude that the shape of the resulting cross section is a parallelogram. A parallelogram is a quadrilateral with opposite sides parallel. In this case, the opposite sides of the square cross section will be parallel, as the slice passes through the midpoints of the edges.

Therefore, the correct answer is D. parallelogram.

It's important to note that a triangular prism is not the correct answer because a triangular prism is a three-dimensional figure with two triangular bases and three rectangular faces. The cross section resulting from the given slice will not have the characteristics of a triangular prism. Option D.

Step-by-step explanation:

Both representations are equivalent and describe the same function.the function rule for this table is:   f(x) = -1/2 x 2

The slope or gradient of a line is a number that describes both the direction and the steepness of the line. A slope of a line is the change in y coordinate with respect to the change in x coordinate.

To write a function rule for a given array, we need to determine how the values ​​in the output column (y) relate to the values ​​in the input column (x).

Looking at the given data, we notice that the output values ​​decrease by 1 every time the input value increases by 2. This suggests that the function is linear and that we can use the slope-intercept form of a linear equation to represent it. .

The slope-intercept form of a linear equation is y = mx b, where m is the slope and b is the y-intercept. In this case, the slope m is -1/2 because the output values ​​decrease by 1 every time the input values ​​increase by 2. The y-intercept b is 2 because the output value is 2 when the input value is 0.

Therefore, the function rule for this table is:

f(x) = -1/2 x 2

where x is the input value and f(x) is the output value.

Alternatively, we can also represent the function in table entries, for example:

f(0) = 2

f(2) = 1

f(4) = 0

f(6) = -1

Both representations are equivalent and describe the same function.

The solution of the given linear equation when

1. there is no solution, is x=-7.

2.one solution, is x=0.

What is a linear equation, exactly?

A linear equation is an equation which can be written in the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept. The slope represents the rate of change of y with respect to x, and the y-intercept is the point where the line crosses the y-axis.

Now,

If there is no solution, then the equation must be contradictory, meaning that it simplifies to a statement that is always false.

5x - 2x + 7 - x = 0

2x + 7 = x

1. x = -7, which leads to a contradiction.

Therefore,

                 there is no solution to the equation when x=-7.

If there are infinitely many solutions, then the equation must be an identity, meaning that it simplifies to a statement that is always true.

5x - 2x + 7 - x = 2x + 7 - x

2x + 7 = 2x + 7

This simplifies to 0 = 0, which is true for all values of x.

2. Therefore, there are infinitely many solutions to the equation.

If there is one solution, then the equation must be consistent, meaning that it simplifies to a statement that is true for only one value of x.

5x - 2x + 7 - x = 3x + 7

2x + 7 = 3x + 7

-x = 0

x = 0

Therefore,

3.              the equation has one solution, x = 0.

Based on the provided information, the table summarizes service times (in seconds) of dinners at a fast food restaurant. To determine the number of individuals included in the summary, we can sum up the frequencies listed in the table:

7 + 24 + 14 + 1 + 4 = 50

Therefore, there are 50 individuals included in the summary.

Regarding the exact values of all the original service times, it is not possible to determine them precisely based on the given information. The table only provides ranges of service times and their corresponding frequencies. We can determine the range within which each individual's service time falls, but we cannot determine the exact value within that range.

Answer: 4/13

Step-by-step explanation:

Number of cards in a deck = 52

Number of spades = 13

Number of aces = 4

Number of ace of spade = 1

Probability of either a spade or an ace :

P(spade or ace) = P(spade U ace)

P(spade U ace) = p(spade) + p(ace) - p(spade n ace)

Probability = required outcome / Total possible outcomes

P(spade) = 13 / 52

P(ace) = 4 / 52

P(spade n ace) = 1 / 52

P(spade U ace) = p(spade) + p(ace) - p(spade n ace)

= 13/52 + 4/52 - 1/52

= 16 / 52 = 4 /13

This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.

Elimination of the parameter means to rewrite the equations in terms of only x and y. To do this, substitute t from one equation into the other equation. Here, the two equations are:x = t1/3 and y = t – 4Substitute t from the first equation into the second equation:y = (x^3) – 4Now the equation is in terms of x and y only.

This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.The rectangular equation, y = (x^3) – 4 can be plotted on a graph. It is a cubic equation. The graph will look like a curve that passes through the point (0, -4) and continues to move towards infinity. The graph will be symmetric to the origin because the equation involves an odd power of x.

If the equation involved an even power of x, the graph would be symmetric to the y-axis. The graph will never touch the x-axis or y-axis, it will only approach them.In conclusion, the rectangular equation y = (x^3) – 4 is derived from the two parameter equations, x = t1/3 and y = t – 4. The graph of this equation is a cubic curve that is symmetric to the origin. The curve passes through (0, -4) and approaches the x and y-axes but never touches them.

Answer:

X = 10

Z = 67

Step-by-step explanation:

We see that the angles are formed by the intersection of two lines.

Angles z and  67° are vertically opposite angles and therefore they are equal to each other

z°= 67°

Angles z and (7x + 43) are supplementary angles. The sum of these angles add up to 180°

z + 7x + 43 = 180

67 + 7x + 43 = 180

7x + 110 = 180

7x = 180 -110 = 70
