A sequence can be taken as the set of numbers having a particular order for all the terms or we can say that arrangement of numbers in some order is known as sequence. There are many types of sequences such as recursive sequences, arithmetic sequences, special sequences, quadratic sequences, geometric sequences etc.

Some examples for sequence are :

2,4,6,8,10,12

3,9,27,81,243

The recursive sequence is the sequence in which any term in the sequence can be find with the help of previous term of that sequence.

In a sequence , first term always known as initial term.

and difference between two terms are known as common difference. It is denoted by d.

General form of sequence is :

[tex]a_1,a_2,a_3,----,a_n[/tex]

where , [tex]a_n[/tex] = last term in sequence.

According to question,

[tex]a_1 = 10[/tex] and [tex]a_n=2a_{n-1}[/tex]

first find the sequence ,

[tex]a_2= 2 a_{2-1} = 2 a_1 = 2(10) = 20\\\\a_3= 2 a_{3-1} = 2 a_2= 2(20) = 40\\\\a_4= 2 a_{4-1} = 2 a_3= 2(40) = 80[/tex]

Thus sequence is 10,20,40,80,...

and the explicit formula for sequence is :

[tex]a_n = 2a_{n-1}\\= > a_n = 2(2a_{n-2}) = 2^2 a_{n-2}\\= > a_n = 2^2 (2a_{n-3}) = 2^3 a_{n-3}\\ .\\.\\= > a_n = 2^{n-1} a_{n-(n-1)} \\ = > a_n = 2^{n-1} .a_1 = 2^{n-1}.10[/tex]

A compound function is when the output of one function is used as the input of another function. If we have a function ff and another function gg, the function fg(x)fg(x) is called "ff of gg of xx" or "fgfg of xx" and is a composition of the two functions.

The order in which functions are applied is important. Find the function of the

function. If you have two or more functions, there can be many different permutations of those functions, giving you many different composite functions.

fg(x)fg (x) can be written f[g(x)]f[g(x)] to indicate that the inner function should be applied before the outer function.

Solution:

Your problem → f(x)=3x, g(x)=((3x)/4)-2, Find f(g(x))

f(x)=3x, g(x)=3x4-2, fog(x)=?

Answer:

UT=27

ST=18

RV=15

US=15

Step-by-step explanation:

If the entirety of RT is 30, then you'd divide that by 2 to receive the number for both RV and VT. 30 divided by 2 is 15.

Because RVS and UVT are vertical, they are both 27. Similarly, RVU and SVT are vertical to each other, so SVT is the same as RVU which is 18.

Rita has a head start, has she began her race 28 Mile ahead of the starting  point.

Since they moved at a constant speed, then there speed is the same through out the journey.

Speed is given by the slope:

(y2 - y1) / (x2 - x1) = (130 - 65) / (2 - 1) = 65 / 1 = 65 mph

Roger's starting position, when t = 0

t = 1 ; distance = 65 miles

t = 0 ; 65 - speed per hour = 65

At t = 0 ; 65 - 65 = 0 miles

Hence, Roger does not have a head start.

For Rita :

Speed is also constant :

Speed or rate = slope of the graph :

(y2 - y1) / (x2 - x1) = (158 - 93) / (2 - 1) = 65 / 1 = 65 mph  

Rita's starting position, when t = 0

t = 1 ; distance = 93 miles

t = 0 ; 93 - speed per hour

At t = 0 ; 93 - 65 = 28 miles

Hence, Rita has a head start of 28 miles.

Using the segment addition postulate, it is found that:

3. The value of x is of x = 9.5.

4. The value of y is of y = ± 5.

The segment addition postulate is a geometry axiom that states that a line segment, divided into a number of smaller segments, has the length given by the sum of the lengths of the segments.

In item 1, we have that the largest segment is of AC, hence it represents the line, while point B splits the segment into two parts, that is, point B is between the other two.

In item 2, we have that:

For item 3, applying the Postulate, we have that:

AB + BC + CD = AD

4 + 4 + 2x - 6 = 21

2x = 19

x = 9.5.

For item 4, due to the midpoint, we have that:

1/3|5x-3|=6

Absolute value equality entered

(1/3) |5x-3| = 6

Clear the absolute-value bars by splitting the equation into two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is (1/3) |5x-3|

For the Negative case, we'll use -(1/3) (5x-3)

For the Positive case, we'll use (1/3) (5x-3)

-(1/3) (5x-3) = 6

Multiply

-5x/3+1 = 6

Rearrange and add up

-5x/3 = 5

Multiply both sides by 3

-5x = 15

Divide both sides by 5

-x = 3

Multiply both sides by (-1)

x = -3

Which is the solution for the Negative Case

(1/3)(5x-3) = 6

Multiply

5x/3-1 = 6

Rearrange and add up

5x/3 = 7

Multiply both sides by 3

5x = 21

Divide both sides by 5

x = (21/5)

When two arcs are parallel to each other, the two arcs between them are congruent. If the two arcs they intersect are the same length, they are congruent.

Chords within a circle can be related in a variety of ways. Parallel chords cut congruent arcs in the same circle. That is, the arcs whose endpoints include one of each chord's endpoints have equal measures.

The lengths of the arcs connecting two parallel chords of a circle are equal. Similarly, if the lengths of the two arcs connecting two distinct chords are the same, the chords are parallel. If two chords have the same length, the arcs between their endpoints will have the same measure.

The mean of the salary is $120000.

By adding up a list of salaries and dividing by the total number of salaries on the list, mean salaries are derived. This means that exceptionally high and extremely low incomes have the same weight in the final average, which is crucial to bear in mind while investigating industry salaries.

By ranking the wages of a group of employees in descending order, you may determine the median base salary by finding the income that is in the middle of the distribution.

Mean=(5*440,00+2*100,000+1*540,000)/(5+2+1)

         =(220,000+200,000+540,000)/8

         =960,000/8

Median is 100,000.

We have to perform the vertical line test.

Use the vertical line test to determine whether a graph accurately represents a function. If a vertical line is moved across it and only ever touches it at one point, the graph is said to be a function. The graph is not a function if the vertical line traverses it more than once.

We have to draw the vertical lines on a graph if the vertical line touches the graph more then 1 then it is not a function if it touches 1 time then it is a function.

1st graph is not a function.

The following set of numbers 2√3, 4√2, and 3√5, can be the measures of the sides of an obtuse triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 2√3, b = 4√2, and c = 3√5

a + b > c     2√3 + 4√2 > 3√5     9.12 > 6.71     True

a + c > b     2√3 + 3√5 > 4√2     10.17 > 5.66    True

b + c > a     4√2 + 3√5 > 2√3     12.37 > 3.46     True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

(2√3)^2 + (4√2)^2 = 44

2. Compare it to the square of the largest side.

(3√5)^2 = 45

44 < 45

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

if they are smaller, then it is an obtuse triangle.

Hence, 2√3, 4√2, and 3√5 can be the measure of the sides of an obtuse triangle.

Answer: 38

Step-by-step explanation: In order to find the area you need to figure out all your sides. Now thankfully it's just a rectangle or this would be a bit more complicated haha!

The first step is to understand what all the sides are. Since you know you have a perimeter of 78 and base of 38, all you need to do is add 38 +38. The reason is that that's on both long sides of a rectangle.  This now leaves you with a number of 76.

Second step: Take the number 76 and subtract it your perimeter 78. This obviously leaves you with the number 2, which you'll have 1 on the shorter sides.

Therefore Area: 38 x 1 = 38

Given that, the isoceles triangle's base angles are equal

let angle D be its vertical angle.

With angle E equal to angle F

angle D+ angle E+ angle F=180'

angle D+ 55'+55'=180',

angle D+ 110'=180'

angle D=180'-110'

angle D=70'.

Figure DEF is an isosceles triangle. The measure of A is 55°, while the measure of B is 70°. As there are two possible measures of D, it can be calculated that the base area equal to 426 square units and the height equals 232 square units.
