The function which contains non-negative real number is y = (x - 1)² and the domain is [0, ∝).

What is real number?

In mathematics, real number are those numbers which contain negative numbers, whole numbers as well as natural numbers. And all the positive real number lies in the first quadrant in the graph. The set of real numbers (denoted by R) includes both rational numbers (positive, negative and zero) and irrational numbers.

According to the question, the given functions whose domain consists of all non-negative real numbers.

Non-negative real numbers lie in the first quadrant. Therefore, the function(d) contains all non-negative real numbers.

Given function: y = (x - 1)²

The domain for this function is: [0, ∝)

Hence, the function which contains non-negative real number is y=(x - 1)² and the domain is [0, ∝).

The rectangle MATH is translated by using the transformation rule P'(x, y) = (x - 7, y - 4) to create the rectangle M'A'T'H'.

In this problem we have the case of a rectangle, a geometric locus, that is translated both horizontally (7 units to the left) and vertically (4 units down). Vectorially speaking, a translation is represented by the following vector sum:

P'(x, y) = P(x, y) + T(x, y)     (1)

Where:

If we know that P(x, y) = (x, y) and T(x, y) = (- 7, - 4), then the transformation rule is derived below:

P'(x, y) = (x, y) + (- 7, - 4)

P'(x, y) = (x - 7, y - 4)

Area of the shape formed by joining triangle , trapezium and rectangle with height 3.5cm is equal to 6.25cm².

As given in the question,

Height of the shape = 3.5cm

length of the rectangle =3cm

Base of a triangle= 8mm

                           = 0.8cm

Parallel sides of the trapezium

side1 = 0.8cm

side 2= 3cm

Let x represents the height

Ratio of the height of rectangle ,trapezium and triangle =2:3:2

2x +3x+2x =3.5

⇒7x =3.5

⇒x =0.5

Height of rectangle =2×0.5

                             = 1cm

Height of trapezium =3×0.5

                               = 1.5cm

Height of the triangle =2×0.5

                                 = 1cm

Area of triangle = (1/2)× 0.8 ×1

                        = 0.4cm²

Area of trapezium = (1/2) ×(0.8+3)×1.5

                            = 2.85cm²

Area of rectangle = 3 ×1

                            =3cm²

Area of the shape =0.4 +2.85 +3

                            = 6.25cm²

Therefore, area of the shape formed by joining triangle , trapezium and rectangle with height 3.5cm is equal to 6.25cm².

Answer:

first choice in the image.

numerator: 12

denominator: 30

Step-by-step explanation:

"Name the numerator and denominator of the fraction that represents the number of trucks that he has loaded out of the total needing to be loaded"

so numerator = "number of trucks that he has loaded"

and denominator = "total needing to be loaded"

Joaquin was asked to load 30 trucks today. So his/her total would be 30.

thus the denominator is 30.

Joaquin has finished loading 12 already, which means he/she has loaded 12. so, the numerator is 12.

The number of books Henry read each number is 3 or 6/2 in a fraction.

A fraction is used to denote a portion or component of a whole. It stands for the proportionate pieces of the whole. The numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

As given in the question,

The number of books read in 2 months is 4.

Henry read books at a constant rate.

The Number of books read by Henry in 1 month is ( 6/2 ) = 3 books.

Sam's score percentage for the whole year was  15 %

This  is a simple question of average,

Sam improved his score by 20% in the 1st semester, and in the 2nd semester, his score improved by 10%.

let 20  in out of 100 and 10 out of 100.

then, the total percentage score is equal to 20+10=30.

and, the total percentage in which out of getting is 100+100 =200

we have to find sam's score percentage for the whole year

which is equal to the total percentage score by sam's divided by percentage which is out of getting and whole multiplied by 100 Because we are finding the percentage.

=>30*100/200=>15 percentage.

The table of values showing the relationship between the number of cakes the bakery makes and the number of bags of four the bakery uses is:

Cakes           |   3    6     9     12      15

Bags of flour|   1     2     3      4        5

A bakery made 9 cakes using 3 bags of flour.

We can introduce a relation between the number of cakes and the bags of flour in the form of a ratio.

Then, cakes : bags of flour = 9 : 3

We can simplify this ratio into 3:1.

So the ratio between the number of cakes and bags of flour = 3:1

We take values for number of bags of flour from 1 to 5 and found the corresponding values for number of cakes using the ratio 3:1.

For each value of number of bags of flour, we just needed to multiply 3 with it to get the number of cakes made.

So using this relationship between cakes made and the amount of flour used to make all their cakes, we can makes table with values:

Cakes           |   3    6     9     12      15

Bags of flour|   1     2     3      4        5

The measure of angle AXY based on the information will be A. 70°.

It should be noted that the value of a right angle is equal to 90°.

In this case, we will add the angles that are given and equate them to 90°. This will be:

6x + 40 + 10 + 2x = 90°

8x + 50 = 90°

Collect like terms

8x = 90° - 50°

8x = 40°

Divide

x = 40° / 8

x = 5°

Therefore, the value of angle AXY will be:

= 6x + 40

where x = 5.

= 6(5) + 40

Both conclusion are correct and the second conclusion is RS = RQ + QS.

The midpoint is halfway between the two end points, Its x value is halfway between the two x values. Its y value is halfway between the two y values.

Given that,

Part 1, If B is between A and C then AB + BC = AC

Then, we need to find the conclusion in Part 2 if Q is between R and S.

The required conclusion can be find out by using the concept of deductive reasoning.

Deductive reasoning involves a pattern which is followed in one argument and by following the same pattern we reach to a conclusion for some other argument.

Now, If we see in Part 1 if B is between A and C then the length of line segment AC is equal to sum of its mid segments AB and BC

⇒ AB + BC = AC

Similarly, if Q is between R and S, then the length of line segment RS is equal to sum of its mid segments RQ and QS

⇒ RS = RQ + QS

Hence, The required Conclusion is RS = RQ + QS.

1. Yes. There is a proportional relationship between the cost of items before tax and the price after tax because they share a constant of proportionality.

2. The constant of proportionality refers to the relative ratio that establishes the proportional relationship between two values.

Other descriptions of the constant of proportionality include:

Two variables possess a proportional relationship when their ratio or product produces a constant.

We can use the equation, k = y ÷ x, to find the constant of proportionality.

For instance, let the cost of items before tax be $100 with a 7% sales tax. The cost of the articles after tax is $107.

For x = -2:

y = 2(-2) + 3

y = -4 + 3

y = -1

For x = -1:
