The explicit Sequence is [tex]a_n = 3. 6^{n-1[/tex].

The 10 term of the sequence is 3,023,308.

A series of terms is referred to as a geometric progression if each next term is produced by multiplying each previous term by a fixed amount. (GP), whereas the common ratio is the name given to the constant value.

Given:

3, 18, 108, 648, ...

First term, a= 3

common ratio, r= 18/3

                          = 6

Now, using geometric sequence

[tex]a_n = a. r^{n-1[/tex]

So, the explicit function is

[tex]a_n = 3. 6^{n-1[/tex]

let us find the fifth term

[tex]a_5[/tex] = 3. [tex]6^4[/tex]

    = 3888

[tex]\frac{4x^{2}+35x+44 }{(x+7)} simplify=4x+ \frac{7x+44}{x+7} \\divide: 4x+ \frac{7x+44}{x+7} \\ simplify= 7+\frac{-5}{x+7} \\\\answer: 4x+7\frac{-5}{x+7}[/tex]

Answer:

x−y=−2

4x−y=4

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

x−y=−2,4x−y=4

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

x−y=−2

Add y to both sides of the equation.

x=y−2

Substitute y−2 for x in the other equation, 4x−y=4.

4(y−2)−y=4

Multiply 4 times y−2.

4y−8−y=4

Add 4y to −y.

3y−8=4

Add 8 to both sides of the equation.

3y=12

Divide both sides by 3.

y=4

Substitute 4 for y in x=y−2. Because the resulting equation contains only one variable, you can solve for x directly.

x=4−2

Add −2 to 4.

x=2

The length of EF is 10.63 units.

The formula to find the distance between the two points is usually given by d=√((c – a)² + (d– b)²).

This formula is used to find the distance between any two points on a coordinate plane or x-y plane.

Given:

From the graph the coordinates of E( -3, -4) and F(4, 4).

Using Distance Formula

EF = √ (4 - (-3))² + ( 4 -(-4))²

EF = √ (4+ 3)² + (4+4)²

EF = √ 7² + 8²

EF = √ 49 + 64

EF = √113

EF = 10.63 units

The function that represents the point (x, y) being reflected across the y-axis is F(x, y) = F(-x, y)

A point (x, y) can be reflected across the y-axis by multiplying the x-coordinate by -1.

This is because the y-axis is a vertical line running through the center of a coordinate plane, and reflecting a point across this line means reversing its position along the horizontal (x) axis.

So, to reflect a point (x, y) across the y-axis, the function can be represented as:

f(x, y) = (-x, y)

This function takes in the coordinates (x, y) of a point and returns the new coordinates (-x, y) after reflecting it across the y-axis.

When Δ BCF is congruent to Δ BDE, then the value of x is obtained as 10.

What is congruence?

In mathematics, the term "congruent" refers to figures and shapes that can be flipped or rearranged to match up with other ones. These forms can be mirrored to produce related shapes.

It is given that Δ BCF ~ Δ BDE.

Since the triangles are congruent so, it can be written that -

BC/BD = BF/BE

Substituting the values in the equation -

52/(52 + 39) = 56/[(56) + (5x-8)]

Simplifying the equation -

52/91 = 56/[(56) + (5x-8)]

4/7 = 56/(48+5x)

Answer: To calculate the final value of an investment with compound interest, you can use the formula:

A = P(1 + r/n)^(nt)

where:

A = final amount

P = initial investment (principal)

r = annual interest rate (expressed as a decimal)

n = number of times interest is compounded per year

t = number of years the investment is held

In this case, we have:

P = 170000

r = 0.04 (4% expressed as a decimal)

n = 2 (semiannually)

t = 7

So plugging these values into the formula:

A = 170000(1 + 0.04/2)^(2*7)

A = 170000(1.02)^14

A = 170000(1.286816)

A = 217,912.72

The final value of the investment after 7 years is 217,912.72 baht.

Step-by-step explanation:

(a) The net change is -1

(b) The average rate of change is -1/5.

Net change of a function is the difference of the output values corresponding to two input values.

Consider the function y = f(x).

Net change from a point x = a to x = b is,

Net change = f(b) - f(a)

Average rate of change of a function from x = a to x = b is,

Average rate of change = [f(b) - f(a)] / [b - a]

The points are (0, 5) and (5, 4).

Here, the value of x on the indicated points are x = 0 and x = 5.

The value of y are f(0) = 5 and f(5) = 4.

Net change = f(5) - f(0) = 4 - 5 = -1

Average rate of change = [f(5) - f(0)] / [5 - 0] = (4 - 5) / 5 = -1/5

Hence the net change is -1 and the average rate of change is -1/5.

The number that replaces the question mark is 5.

Number is a mathematical object used to count, measure, and label. It is an abstract concept that can be represented by a symbol, such as a numeral or word. Numbers are used in various ways, including counting, measuring, and labeling. They can also be used to represent relationships between objects and ideas, and to measure the size, volume, and distance of objects.

This is because the pattern of the sequence is to add the two numbers that are next to each other together to get the next number. In the sequence, the two numbers that are next to the question mark are 6 and 7. When 6 and 7 are added together, the result is 13.

Answer: x is equal to 0.88

Step-by-step explanation:

To solve for x, we can start by simplifying both sides of the equation:

89(54x - 36) + 2 = -34(-40 + 16x) + 90x

First we can simplify the left side of the equation:

89(54x - 36) + 2 = 4846x - 3204 + 2 = 4846x - 3202

Now we can simplify the right side of the equation:

-34(-40 + 16x) + 90x = -34(16x - 40) + 90x = -544x + 1360 + 90x = -454x + 1360

Now we can set the left side of the equation equal to the right side and solve for x:

4846x - 3202 = -454x + 1360

Now we can add 454x to both sides and subtract 1360 from both sides

5,300x = 4660

x = 4660/5300

x = 0.88

Therefore, x is equal to 0.88

Answer:

0.86

Step-by-step explanation:

89(54x-36)+2=-34(-40+16x)+90x

For the given similar triangles ΔBCF ~ΔBDE, the value of x is, 10

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

One triangle, ΔBCF

one segment CF which is intersecting sides BD & BE

ΔBDE has one similar triangle inside, which is ΔBCF

Triangles ΔBDEand ΔBCF similar,

So, we can say ΔBCF ~ΔBDE

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, BD/BE = BC/BF
