Please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!

Answer:

In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

Answer:

Linear

Step-by-step explanation:

The type of function which is represented in the table is quadratic, the correct option is B.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The table

Now,

Looking at the table, we can see that each input value is paired with only one output value, so the relationship is a function. We can also see that the difference between the output values is not constant, so the function is not linear. The quotient of the output values is not constant either, so the function is not exponential. The quotient of the output values does not change in a predictable way, so the function is not logarithmic.

Therefore, by the function the answer will be quadratic.

Answer:

x = 15

y = 25

Step-by-step explanation:

WV = NP

WX = NM

VX = PM

VX/PM = WV/NP

8/20 = 6/x

8x = 120

x = 15

WV/NP = WX/NM

6/15 = 10/y

6y = 150

y = 25

Answer:

8. 15

10. 90

12. 36

Step-by-step explanation:

8.

The mean of the 5 data is 51.

(55 + 60 + 35 + 90 + x) ÷5 = 51

(240 + x) ÷5 = 51

240 + x = 255

x = 15

10.

The mean of the 5 data is 127.

(100 + 112 + 98 + 235 + x) ÷5 = 127

(545 + x) ÷5 = 127

545 + x = 635

x = 90

12.

The mean of the 5 data is 40.

(34 + 56 + 45 + 29 + x) ÷5 = 40

(164 + x) ÷5 = 40

164 + x = 200

x = 36

Answer:

17

Step-by-step explanation:

We can use this formula:

[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex] where x and y indicate the coordinates of the two points

[tex]\sqrt{4-(-4)^2 + (8-(-7)^2} = \sqrt{64 + 225} = \sqrt{289} = 17[/tex]

Answer:

17

Step-by-step explanation:

You are given two points so you use the distance formula

[tex] \sqrt{( {x 2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]

Substitute your points into the formula

Answer: 1. -5 because what you do on the left you do on the right

Answer:

Step-by-step explanation:

Convert each number to its decimal equivalent for easier comparison with the other numbers:

1/8 = 0.125        1 (smallest)

2/4 = 0.50         3

8/4  = 2.0           4

3/15  = 0.20        2

2 2/7 = 2.28        6  (largest)

20/10​ = 2.00       5 (next to largest)

The smallest number is 1/8 (see above), and the largest is 2.28 (2 2/7).

Answer:

The answer is below

Step-by-step explanation:

Let x represent the unknown weight of each of the circles, since there are three of those type of circles, hence the unknown weight is 3x.

From the diagram, the sum of the total weight at one side must be equal to the sum of the total weight at the other side so that they can be balanced, hence:

3x + 4 = 12

subtracting 4 from both sides:

3x + 4 - 4 = 12 - 4

3x = 8

Dividing through by 3:

3x/3 = 8/3

x = 8/3

The weight of each of the circle is 8/3 grams
