What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

We know that the function are relation when the input values only be distinct and the output values can be different or same.

So, according to that

{(1,3), (3, 7), (5, 11), (7, 15), (9, 19)} is a function.

and, {(1, 3), (1,7), (5, 11), (5, 15), (9, 19)} is not a function.

and, {(-2, 4), (-1, 1), (0, 0), (1, 1), (2, 2)} is a function

and, {(2,4), (1, 1), (0,0), (1,-1), (2,-4)} is not a function.

and, {(6,3), (4, 1), (2, 1), (0, -1), (-2,-3)} is a function.

and, {(1,3), (3,7), (3, 11), (7, 15), (9,19)} is not a function.

Answer:

10.) suplementary  because they both make 180

11.) Congurent because they are vertical angles because they are on different sides of the line.

12.) congruent because they both are on the same line and are linear

13.) Supplementary beacuse the two angle create 180 degrees

14.) Suplementary beacuse the two angle create 180 degrees and are linear

Answer:

The height of the candle after 14 hours is 15.4 centimeters

Step-by-step explanation:

A linear function is a polynomial function of the first degree of the form:

f(x)= m*x + b or y= m*x + b

where m is the slope of the function and b is the ordinate at the the y-intercept.

In this case height=m*time + b

Given two points of the line, point 1 (x1, y1) and point 2 (x2, y2), we can find the equation of the line or linear function.

You must first find the slope of the line using the expression:

[tex]m=\frac{y2 - y1}{x2 - x1}[/tex]

In this case you know the two points are (x1, y1)= (10,17) and (x2, y2)=(21,12.6)

So the slope is:

[tex]m=\frac{12.6-17}{21-10}[/tex]

m= -0.4

Now you find the value of b, replacing m in the equation, the values ​​of x and y by the values ​​of the coordinates of one of the points and solving for b to obtain its value.

Replacing (x1, y1)= (10,17) and m=-0.4 in the expresion y=m*x+b:

17= -0.4*10 + b

and solving you get:

17= -4 + b

17 + 4= b

21= b

So: height= -0.4*time + 21 where the height is expressed in centimeters and the time in hours.

To calculate the height of the candle after 14 hours, you simply replace the time by 14:

height= -0.4*14 + 21

height= 15.4

The height of the candle after 14 hours is 15.4 centimeters

Opposite angles are congruent, and consecutive angles are supplementary. All sides are congruent by definition. The diagonals bisect the angles

Part 1) What is the measure of angle  ?

-----> remember that the diagonals bisect the angles

Part 2) What is the measure of angle  ?

Remember that

In a rhombus consecutive angles are supplementary

Answer:

X = 2.5.

Step-by-step explanation:

I believe 2.5 should be the solution. Here is how you can solve the equation:

Combine like-terms, First combine the simpler numbers, add 0.8 to 5.6X + 3.95. This should get you the equation: 7.5X = 5.6X + 4.75. Then combine 7.5X and 5.6X by subtracting 5.6X from 7.5X to get the equation: 1.9X = 4.75.

Now, divide 4.75 by 1.9. By dividing these two numbers you should get the equation: X = 2.5.

Step-by-step explanation:

Answer:

The total bill = $20.85

Annie = $7.95

Suz = $4.17

Cynthia = $8.80

Step-by-step explanation:

Let the total bill = $x

For Annie

Annie, you had 3 slices and a medium soda so you should pay one-third of the bill. I'll chip in a dollar more than that, replied Annie.

Annie = 1/3 of x + $1

= 0.33x + $1

For Suz

And since you had only 2 slices and also ordered a small soda, you should pay 20% of the bill.

20% of x = 1/5x

= 0.2x

Cynthia said I ate 3 slices and had a large soda so I'll pay the remaining $8.80.

0.33x + $1 + 0.2 x + $8.80 = $x

Collect like terms

$1 + $8.80 = x - 0.33x - 0.2x

$9.80 = x - 0.53x

$9.80 = 0.47x

x = $9.80/0.47

x = $20.85106383

≈ $20.85

Therefore,

For Annie,

The total amount she is paying is

0.33x + $1

= 0.33 × $20.85 + $1

= $6.95 + $1

= $7.96

For Suz

= 0.2x

= 0.2 × $20.85

= $4.17

For Cynthia

= $8.80
