Step-by-step explanation:

[tex]a^{-1} =\frac{1}{a} \\24^{-1} =\frac{1}{24}[/tex]

A negative exponent is converted to a fraction while the power goes to the base which is at the denominator.

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

and, the 10 term of the sequence is

[tex]a_5[/tex] = 3. [tex]6^9[/tex]

Answer: Justin is 9 years old, Peyton is 6 years old and Matt is 24 years old

Step-by-step explanation: Let the age of Justin be x years .

And Peyton is three years younger than Justin, therefore Peyton age is

(x-3) years

And Matt is four times as old as Peyton, therefore Matt age is

4(x-3) years

And it is given that

x + x - 3 + 4 (x - 3) = 39

x + x - 3 + 4x - 12 = 39

6x - 15 = 39

6x = 54

x = 9

Therefore , Justin is 9 years old, Peyton is 6 years old and Matt is 24 years old .

Their ages Mario is four years old, while Martina is five.

If a person is "x" years old now, then "n" years from now, that person will be "x + n" years old. The age of this would be equal to x - n years n years ago.

Mario is four years old, while Martina is five.

Explanation:

2x -y = 6 adding two to the number 4x -2y = 12

3x + 2y = 23

The sum of the two figures

4x - 2y = 12

3x + 2y = 23

7x = 35 by 7 multiply both sides.

Marina is x years old.

2x - y = 6 Put 5 in place of x, then figure out y.

2(5) -y = 6

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.

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

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.

Answer:

To multiply using fraction form, we can convert the decimal numbers to fractions and then multiply them together.

4.4 can be written as 44/10

3.2 can be written as 32/10

So the multiplication would be:

(44/10) * (32/10) = (4432)/(1010) = 1408/100

To simplify this fraction, we can divide the numerator and denominator by their greatest common factor which is 4, we get:

1408/100 = 352/25

So the product of 4.4 and 3.2 is 352/25 in fraction form.

The definition of a rate of change is a rate that expresses how one quantity changes in relation to another quantity. When d(t)=2t is stated, the average speed from t=5 to t=9 is 28 feet or 2 feet per second.

A rate of change is a rate that describes how one quantity changes in relation to another quantity.

d(t)=2t² is given, we need to find the average speed in feet per second from t=5 to t=9.

d(t)=2t².

The average rate of change is calculated by the formula:

d(t₂) - d(t₁) / t₂ - t₁

So plug in 5 as t₁ and 9 as t₂.

=> d(9) - d(5) / 9 - 5

=> (2×81) - (2×25) / 9 - 5

=> 162 - 50 / 4

=> 112 / 4 = 28

Therefore the average speed is 28 feet.

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

4806x-3204+2=1360-544x+90x

4806x+500x-90x=3204-2+1360

5260x=4562

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.

Please note that this is a simple interest calculation, and in real world some other factors like taxes, fees, etc should be taken into account.

(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.

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)

4(48+5x) = 56 × 7

192 + 20x = 392

20x = 392 - 192
