hich of the relations given by the following sets of ordered pairs is not a function? {(5,2),(4,2),(3,2),(2,2),(1,2)} {(-4,-2),(-1,-1),(3,2),(3,5),(7,10)} {(-8,-3),(-6,-5),(-4,-2),(-2,-7),(-1,-4)} {(-6,4),(-3,-1),(0,5),(1,-1),(2,3)}

Answers

Answer 1

{(-4,-2),(-1,-1),(3,2),(3,5),(7,10)} is not the function .

• In mathematics, ordered pair is a pair of numbers which are written in a specific order. They are generally written in (x,y) form. For example (3,5) is a ordered pair.

• Function can also be represented by a set of ordered pairs. A function Is a set of ordered pairs in which no two different ordered pairs have same value of x coordinate.

Case 1 : {(5,2),(4,2),(3,2),(2,2),(1,2)}

No two ordered pair have the same value of x coordinate. So it is a function.

Case 2 : {(-4,-2),(-1,-1),(3,2),(3,5),(7,10)}

Two ordered pair have the same value of x coordinate (3,2) and (3,5). So, it can not be considered as a function.

Case 3 : {(-8,-3),(-6,-5),(-4,-2),(-2,-7),(-1,-4)}

No two ordered pair have the same value of x coordinate. So it is a function.

Case 4 : {(-6,4),(-3,-1),(0,5),(1,-1),(2,3)}

No two ordered pair have the same value of x coordinate. So it is a function.

Therefore, {(-4,-2),(-1,-1),(3,2),(3,5),(7,10)} is not the function.

Dr. Gordon has a scale drawing of a building site thr drawing uses the scale 2 in on the drawing for every 100 ft on the building site dr gordon marks a 6 in. by 3.2 in section of the draeing to show the section she will search what is the area of the section she will search?

Answers

The required area of the section Dr. Gordan will search is equal to 48,000ft².

As given in the question,

Scale used by Dr. Gordan

2 in = 100 ft

⇒1 in = 50 ft

Dr. Gordon marks a 6 in. by 3.2 in section

Length = 6 in

= ( 6 × 50 )ft

= 300ft

Width = 3.2in

= ( 3.2 × 50 )

= 160ft

Area of the section = length × width

= 300 × 160

= 48,000 ft²

Therefore, the required area of the section Dr. Gordan will search is equal to 48,000ft².

Which answer choice do I pick?

Answers

Answer:

D. f(x) = 8x

Step-by-step explanation:

At each increasing x point, the y point increases by 8, this means that for each x increasing by 1, y increases by 8, which means y = 8x

Answer:

Fourth choice, f(x) = 8x

Step-by-step explanation:

y is going up or down and x is left or right, u riht the slope like y/x

so it's going up 8 units every 1 unit it goes to the right so it's 8/1 which is 8 so 8 is ur slope

The mean of 20 observations is 12.5. By error, one observation was noted as (-15) instead of 15. Then the correct mean is ___?

Answers

Answer:

The correct mean is -12.5.

Step by step explanation:

If one of the 20 observations is a negative number, then the mean would be negative. This is because, when a negative number is in contact with (meaning added, subtracted, multiplied by) a positive number, the whole answer is negative, because it's opposite signs.

Use a two-column proof to prove the Triangle Proportionality Theorem:

*image attached*

Answers

Answer:

A line ED parallel to one side of the triangle {CB} has intersected the other two sides of the triangle [AB and AC] making the sides proportional.

Step-by-step explanation:

The Triangle Proportionality Theorem states that:

If a line parallel to one side of a triangle intersects the other two sides then it divides those sides proportionally. The segments joining midpoints of the two sides of the triangle will be parallel to the third side and half the length.

This means if a line divides two sides of a triangle proportionally, then it is parallel to the third side.

In this case;

AD/AB =AE/AC is true because;

A line ED parallel to one side of the triangle {CB} has intersected the other two sides of the triangle [AB and AC] making the sides proportional.

The type of reaction is Decomposition reaction.

What is Decomposition reaction?

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation:

AB → A + B.

Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Given reaction:

[tex]C_{12}H_{22}O_{11}[/tex] → 12C + 11[tex]H_{2}O[/tex]
