What is a function?

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

End behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis. Said differently, the end behavior of a function explains the graph's trend when we look at the right end of the x-axis (as x approaches +∞) and the left end of the x-axis (as x approaches -∞).

58 Find the missing angle measures: C 42 9 А. 10 B X х В. A 40 4 0 12 S 13 T 14 X 48 57 41 76 SIT 46

Answers

Let us first solve the triangle on the right side involving angle x.

Recall that the sum of angles in a triangle must be equal to 180°.

So we can write

[tex]\begin{gathered} 41+78+x=180 \\ 119+x=180 \\ x=180-119 \\ x=61\degree \end{gathered}[/tex]

Therefore, the angle x is equal to 61°

Now let us solve the triangle involving angle S and T.

Again applying the property that the sum of angles in a triangle must be equal to 180°

[tex]\begin{gathered} 48+57+S=180 \\ 105+S=180 \\ S=180-105 \\ S=75\degree \end{gathered}[/tex]

As you can see, the angle S and T form a straight line angle.

Recall that a straight line angle is equal to 180°

[tex]\begin{gathered} S+T=180 \\ 75+T=180 \\ T=180-75 \\ T=105\degree \end{gathered}[/tex]

Therefore, angle S = 75° and angle T = 105°

Now let us solve the remaining figure.

On the right side of the figure, apply the property that the sum of angles in a triangle must be equal to 180°

[tex]\begin{gathered} A+42+40=180 \\ A+82=180 \\ A=180-82 \\ A=98\degree \end{gathered}[/tex]

As you can see, the angles A and B are opposite angles.

We know that opposite angles are equal.

[tex]\angle A=\angle B=98\degree[/tex]

Now we know the angle B so let us apply the property that the sum of angles in a triangle must be equal to 180°

[tex]\begin{gathered} B+48+C=180 \\ 98+48+C=180 \\ 146+C=180 \\ C=180-146 \\ C=34\degree \end{gathered}[/tex]

Therefore, angle A = 98° and angle B = 98° and angle C = 34°

Help me please its homework and its the last question ;-; . Also hope you have had a good day ;}

Answers

The value of the angle x will be equal to 113.5°.

An angle may be defined as the figure which can be formed from two rays joining at a point. The lines will be called as the sides of the angle and the point at which the rays join is called vertex of the angle. There are generally 5 types of angles namely Acute angle, Obtuse angle, Reflex angle, Right angle and Complete angle. The value of a complete angle will be given as 360°. Since, in the question all the angles are measured to the nearest. So, the value of 59° could actually be something between 58.5° and 59.5°. Analogously, 108° is between 107.5° and 108.5°, and 81° is between 80.5° and 81.5°. Now, the summation of all four angles will be equal to 360°.

x + 58.5° + 107.5° + 80.5° = 360°

=> x = 360° - (58.5° + 107.5° + 80.5°)

=> x = 360° - 246.5°

=> x = 113.5° which is the required value.

If each quadrilateral below is a trapezoid, find the missing measures.

Answers

Applying the definition of the adjacent angles of a trapezoid, the value of x in quadrilateral TUVS is: x = 4.

What are the Adjacent Angles of a Trapezoid?

The adjacent angles of a trapezoid are the angles that are found on the same leg of the trapezoid, and they are said to be supplementary to each other because they have a sum of 180 degrees.

Given that quadrilateral TUVS is a trapezoid, where angles SVU and TSV are adjacent angles, therefore:

m∠SVU + m∠TSV = 180°

m∠SVU = 139°

m∠TSV = (14x - 15)°

Substitute

139 + (14x - 15) = 180

139 + 14x - 15 = 180

Combine like terms

124 + 14x = 180

14x = 180 - 124

14x = 56

14x/14 = 56/14

x = 4

Find the rates of change in population for both parks between 2009 and 2014, and determine which park showed faster population growthduring those years.

Answers

The table and graph given show the information about two national parks.

It is required to find the rate of change of the population of the two parks between 2009 and 2014, and then determine the park that shows faster population growth during those years.

Notice that the variable x represents the number of years after 2005.

Hence, the years 2009 and 2014 represent, x=4 and x=9, respectively.

The formula for the rate of change of a function f(x) between x=a and x=b is given by the formula:

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Calculate the rate of change for park A:

Substitute a=4 and b=9 into the formula:

[tex]\frac{f(9)-f(4)}{9-4}[/tex]

Substitute f(9)=2870 and f(4)=2370 from the table for park A into the expression for the rate of change:

[tex]\frac{2870-2370}{9-4}=\frac{500}{5}=100\text{ swallows per year}[/tex]

Calculate the rate of change for park B:

[tex]\frac{f(9)-f(4)}{9-4}[/tex]

Substitute f(9)=2800 and f(4)=2200 from the graph of park B:

[tex]\frac{2800-2200}{9-4}=\frac{600}{5}=120\text{ swallows per year}[/tex]

Notice that the rate of change in population for park B is higher than that of park A.

Hence, park B showed faster population growth during those years.

Answers:

Rate of change for park A= 100 swallows per year.

Rate of change for park B= 120 swallows per year.

Park B showed faster population growth during those years.

Recall that when two angles add to give 90 degrees, they are called "complementary angles" This is the case here where you are adding an unknown angle to one that measures 51 degrees to obtain a right angle (90 degrees)

The unknown angle (?) is called the "complementary angle to the 51 degree one.

Please select the third option :

C. Complementary.

Do you remember how it looks an angle that measures 90 degrees? It looks like the angle formed by a square edge, or by two lines that are perpendicular to each other.

When you have two angles one in contact (adjacent) to the other and the two together complete a right angle , those two angles are called complementary angles. There is nothing profound to derive from that, but that it is simply a definition.

1. A sum of money is to be shared among three friends Paul, Mark and Anna in the ratio 2: 3: 5 respectively. If Paul received $ 48,000. Determine


a. Anna’s Share
b. Mark’s share.
c. The total sum

Answers

a)Sum of money share by Anna is $120000

b)Sum of money share by Mark is $72000

c) The total sum the three friends have is $ 240000

The ratio of the amount of money shared among three friends is 2: 3: 5.

Let's take the common factor to be x.

Sum of money Paul has = 2x

Sum of money Mark has = 3x

Sum of money Anna has = 5x

It is given that Paul receive $48000

So,

2x = 48000

x = 24000

a) Anna's share = 5x

                          = 5× 24000

                          = $120000

b) Mark's share = 3x

                          = 3 × 24000

                          = $72000

c) The total share = 2x + 3x + 5x

                             = 10x

                             = 10 × 24000

                             = $240000

Therefore the sum of money share by Anna is $120000, Mark is $72000 and the total sum of money is $240000.
