The domain of the function f(x) = x³ is all real numbers

The term domain in function is defined as the set of possible input values and in the graph it consists of all the input values shown on the x-axis.

Here we have the function f(x) = x³.

Now, we have to find the domain of the function.

As per the definition we all know the the set of all x values in the graph is defined as the domain of the function.

As per the given graph we have identified that the domain is all real numbers because the horizontal extent of the graph is the whole real number line.

Here we have also know that the same applies to the vertical extent of the graph, so the domain and range include all real numbers.

The values of angles x and y in the trapezium are 48 and 115 degrees.

A trapezium is a quadrilateral with one pair of sides parallel to each other. Sum of angles pair between parallel line is 190 degrees.

Therefore, let's find x and y in the trapezium.

y + 132 = 180

subtract 132 from both sides of the equation

y + 132 - 132 = 180 - 132

y = 48 degrees

x + 65 = 180

subtract 65 from both sides of the equation

x + 65 - 65 = 180 - 65

x = 115 degrees.

When we compare the given expression with the slope-intercept form, we get the required slope. Here, the slope is -3.

A line's slope or gradient numerically expresses its steepness and direction. It provides the ratio of how much y alters when x alters by a particular amount. Since m is the slope and c is the y-intercept, y=mx+c is the general form. This is the slope-intercept form.

Compare the given expression y=-3x-7 with the slope-intercept form. We get, the slope value as m=-3 and the intercept value as c=-7. Therefore, the required answer is -3. So the value of y changes with -3 times of x.

Option B) The cat weighs 4 kilograms when it is 7 months old.  is the correct answer.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

Given, w gives the weight of the cat, in kgs, when it is "m" months old.

Since w gives weight in kilograms. It outputs weight when we tell the age in months,

thus,

w(7) means weight when the cat is 7 months old.

and w(7) = 4 represents that the cat weighs 4 kilograms when the age of the cat is 7 months.

The positive difference between the two answers is 8.6 units.

Rachel first calculates the expression as it is written and rounds the answer to the nearest whole number:

She then calculates it again, but rounds each of the 3 numbers in the expression to the nearest integer:

$\frac{3}{2} 18$ = 27

The positive difference between the two answers is:

18.4 - 27 = -8.6

So, the positive difference between the two answers is 8.6 units.

It's worth noting that when you round the numbers before performing the calculations, the result may be different than the exact result, but it can be useful in some cases to have an approximation of the answer.

Answer:

There are 105 boys in preschool.

Step-by-step explanation:

We can set an equation:

(boys/girls)=3/4;

boys + Girls = 245

We know that Boys = 3/4* Girls

substitute it into the second equation:

3/4* Girls + Girls = 245

(3/4 + 1) * Girls = 245

(7/4)Girls = 245

Girls = 2454/7

Girls = 140

So there are 140 girls in preschool.

Now we can use the ratio of boys to girls (3:4) to find the number of boys:

boys = (3/4) * 140 = 105

There are 105 boys in preschool.

The scale factor of AABC dilation of ADEF with center (0, 0) is 3.

Scale factor is a numerical value used to indicate the proportional change in the size of an object or image. It is often expressed as a fraction or ratio, for example 1:2, where the first number (1) represents the original size, and the second number (2) represents the new size. This is also referred to as a "scaling factor," since it indicates how much larger or smaller the new size is compared to the original size. Scale factors can be used to resize objects in different directions, such as width, height, and depth.

This means that each point of ADEF was scaled up by a factor of 3. This means that the length and width of ADEF were multiplied by 3 to make the new figure AABC. For example, if the length of ADEF was 6, then the length of AABC would be 18. Similarly, if the width of ADEF was 9, then the width of AABC would be 27.

The range of f(x)= x² is [0, +∞) or the set of all non-negative real numbers.

The range of a function is the set of all possible output values (y-values) for the function.

To determine the range of the function f(x) = x², plug in some values for x:

If x = 0, then f(x) = 0² = 0, which is a non-negative real number.

If x = 1, then f(x) = 1² = 1, which is a non-negative real number.

If x = -1, then f(x) = -1² = 1, which is a non-negative real number.

For any real number x, x² is always non-negative, so the range of the function is all non-negative real numbers [0, +∞).

Alternatively, we can also see that the parabola of the function opens upward and the vertex is at the origin. Therefore, the range of the function is all non-negative real numbers.

The slope of the line passing through the points (- 9, 3) and (7, 7) is 1/4.

In the given question we have to find the slope of the line passing through the points (- 9, 3) and (7, 7).

The formula for finding the slope of line is

m = [tex]\frac{y(2)-y(1)}{x(2)-x(1)}[/tex]

The given points are (- 9, 3) and (7, 7).

From the given point;

x(1) = -9, y(1) = 3, x(2) = 7, y(2) = 7.

Now putting the value in the formula

m = [tex]\frac{7-3}{7-(-9)}[/tex]

m = [tex]\frac{4}{7+9}[/tex]

m = [tex]\frac{4}{16}[/tex]

m = 1/4

The measure of <HMG is 40 degree.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Given:

In triangle HJL

HJ = HL (given)

let <HJL = <HLJ= 75  (Angles opposite to equal side also equal)

Using Angle Sum property in HKL

75 + 90 + <KHL = 180

<KHL = 180 - 165

<KHL = 15

Now, in Triangle HKM

<KHM = 35 + 15 = 50

So, Using Angle Sum property

50 + 90 + <HMK = 180

<HMK = 180- 140

<HMK = 40
