According to the given data the domain of g[f(x)] is all real numbers.

√2 and -√2.

The correct option is 1.

The collection of potential inputs into a function, or the set of input values for which the function is defined, is known as the domain of the function. The collection of things that the machine will accept as inputs is known as the domain in the function machine paradigm.

We will respond to this question using two functions:

f(x) = x² and g(x)

= x²/ x-2

Because the domain of f(x) is the set among all real numbers,

Except for 2, the domain of g(x) is all real integers.

Now

g[f(x)]= g(x²)

=  x²/ x-2

Except for real numbers, the domain of g[f(x)] is all real numbers.

According to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.

A popular charting tool is a histogram. On an interval scale, it is used to describe either discrete or continuous data. It is widely used to show the key properties of distribution of the data in an easy-to-understand fashion.

Examine the histogram to see if it shows a normal distribution. Once you've plotted all of the frequencies here on the histogram, it will take on a shape. If the shape resembles a bell curve, it indicates that perhaps the frequencies are evenly distributed. A peak would appear on the histogram.

Ms. Wendell sells 25% of her her cows. While purchasing a cow, it is important to remember that weight is an important factor. While there may be some exceptions, the majority of cows sold in the United States weigh between 800 and 1200 pounds.

So, if your farm falls within this range, it would be wise to consider buying a cow from Mrs. Wendell .

Additionally, based on these numbers alone, it would make sense for you to purchase one or more cattle from Mrs. Wendell.

Therefore,

The smallest positive integer is 1.

Positive Numbers definition the meaning of positive whole numbers in numerical states that "Numbers that are more noteworthy than zero are positive numbers". Numbers can be grouped into three kinds: negative whole numbers, zero, and positive whole numbers. Normal numbers are extremely normal to people since they come from counting objects like apples or sheep.

If s is integer

S = n (a + l)/2

Normal numbers can be utilized to assess your assets, the amount of you possess. There is no biggest regular number. The following regular number can be found by adding 1 to the ongoing normal number, creating numbers that go on "for eternity". Every one of the numbers we use for counting are positive whole numbers. Positive numbers are entirely of a bigger gathering of numbers called whole numbers. Numbers are the entire numbers, both positive and negative. By entire numbers we mean numbers without divisions or decimals.

5. Addition property of equality

6. Substitution property

Step-by-step explanation:

The distance between (-3, 6) and (5, 2) is 4√5 by using the distance formula.

Distance between two points in x y plane by distance formula is:

= √{(x₁ - x₂)² + (y₁ - y₂)²}

Substituting the values of the points:

= √{( -3 - 5 )² + ( 6 - 2 )²}

Solving it further:

= √{( -8 )² + ( 4 )²}

= √{ 64 + 16 }

= √80

= √(2× 2 × 2 × 2 ×5 )

= 2×2× √5

= 4√5

So, the distance between (-3, 6) and (5, 2) is 4√5 by using the distance formula.

For the given wire, the length of each piece of wire will be 76inch and 24 inch and quadratic equation will be x² - 100x + 1800 = 0

An algebraic equation of a second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.

Given,

Length of wire = 100 inches

Sum of the areas of two squares = 400 inch²

let length of one wire - x

the length of other wire will be - 100-x

Now, the area of the square = Side²

⇒ (x/4)² + ((100 - x)/4)² = 400

⇒ (1/4)²  (x² + 10000 + x² - 2(100)(x)) = 400

⇒ 10000 + 2x² + - 200x = 400 × 16

⇒ 2x² - 200x = 6400 - 10000

⇒ 2x² - 200x = - 3600

⇒ x² - 100x + 1800 = 0

⇒On solving for the value of x, we have x= 76 and 24

Now,

76/4 = 19,

24/4 = 6

So, we have the length of each wire as 76inch and 24inch

Step-by-step explanation:

The value of x for given equation (2x - 20) /3 = 2x is x = -5

For given question,

we have been given an equation  2x minus 20 divided by 3 = 2x

i.e., (2x - 20) /3 = 2x

This equation models temperature change, where x represents the difference in degrees in the last 24 hours.

We need to solve given equation for x.

(2x - 20) /3 = 2x

(2x - 20)  = 3(2x)                ...........(Multiply by 3 on both sides)

2x - 20 + 20 = 6x + 20      ...........(Add 20 to both sides)

2x - 6x = 6x + 20 - 6x       ..........(Subtract 6x from both sides)

-4x = 20                            

x = -5                                  ..........(Divide by - 4 on both sides)

Therefore, the value of x for given equation (2x - 20) /3 = 2x is x = -5

If the area of the rectangle (as shown below in the reference.jpeg attached hereby for reference) is 32 sq. units, then the area of the triangle shown besides the rectangle will be 16 sq. units.

As per the question statement, area of a rectangle (as shown below in the reference.jpeg attached hereby for reference) having a length of 8 units and width of 4 units is 32.

We are required to calculate the area of the triangle (shown beside the above-mentioned rectangle in the reference.jpeg attached hereby).

From the diagram, it is clear that that base of the triangle is 4 units and since it is a right-angled triangle, it's altitude or height is 8 units.

Now the formula to calculate the area of a triangle (A) having base "b" and height "h", goes as [tex]A=(\frac{1}{2}*b*h)[/tex]

And, C means the cost

Now

We know that

Profit = R - C

Profit = Revenue - cost

=195x - (160x + 18000)

= 195x - 160x - 18000
