Solve for n. Can someone please help.

Answer:

12 inches.

Step-by-step explanation:

We know that the length of the stamp is 4/3 inches.

Let the width be x inches.

Then the area of the actual stamp is:

[tex]\frac{4}{3}x\text{ inches}^2[/tex]

We know that the rectangular picture of the stamp is 81 times greater than the actual stamp’s area. Therefore, the area of the picture is 81 times the above. So:

[tex]81(\frac{4}{3}x)\text{ inches}^2[/tex]

So, the area of the rectangular picture is the area of the actual stamp multiplied by a scale factor k.

When we use the scale factor to scale area, we need to square it. Hence, the area of the actual stamp times the scale factor squared is equal to the area of the rectangular picture. Therefore:

[tex]\frac{4}{3}x(k^2)=81(\frac{4}{3}x)[/tex]

Let’s solve for the scale factor. Divide both sides by 4/3(x). Hence:

[tex]k^2=81[/tex]

Take the square root of both sides:

[tex]k=9[/tex]

So, the scale factor from the actual stamp to the picture is 9.

So, the actual stamp has a length of 4/3.

Then ThThe length of the stamp’s picture will be:

[tex]\frac{4}{3}k[/tex]

Substitute 9 in for k to get:

[tex]=\frac{4}{3}(9)=12[/tex]

So, the length of the stamp’s picture is 12 inches.

Complete question :

In one year, the population of Douglas, the former copper mining town on the U.S.-Mexico border, shrunk by 200. Over the last ten years, the town’s population is going down at an average rate of 1.16% per year. Douglas’ current population in November 2020 is 15,140. a. Write an equation to model the population decay of Douglas using the data given. b. If the town’s population loss continues to occur at this rate, what will the population of Douglas in 6 months from now? Round your answer to the nearest integer. c. If the town’s population loss continues to occur at this rate, what will the population of Douglas in one year? Round your answer to the nearest integer. d. If the town’s population loss continues to occur at this rate, what will the population of Douglas in November 2027? Round your answer to the nearest integer.

Answer:

15052 ; 14,964 ; 13953

Step-by-step explanation:

Given that:

Rate of population decline = 1.16% annually

Population in November 2020 = 15140

A = I(1 - r)^t

Where ;

A = final population

I = initial population

r = rate of decline

t = number of years

Population in 6 months

t = 6 months = 0.5 year, r = 1.16% = 0.0116

A = 15140(1 - 0.0116)^0.5

A = 15140(0.9884)^0.5

A = 15051.931

A = 15052 ( nearest integer)

Population after 1 year :

A = 15140(1 - 0.0116)^1

A = 15140(0.9884)^1

A = 14964.376

A = 14964 ( nearest integer)

Population in 2027:

t = 2027 - 2020

A = 15140(1 - 0.0116)^7

A = 15140(0.9884)^7

A = 13952.596

A = 13953 ( nearest integer)

Calculate 12 to the power of -5 and get 1/248832:

35831808 - 1/248832 | 12²

Subtract 1/248832 from 35831808 to get 8916100448255 / 248832:

8916100448255 / 248832 | 12²

calculate 12 to the power of 2 and get 144:

8916100448255 / 248832 | 144

Express 8916100448255 / 248832 | 144 as a single fraction.

8916100448255 / 248832 X 144

Multiply 248832 and 144 to get 35831808:

Answer:

Result = 0.0045

Step-by-step explanation:

Given

[tex]0.09 * 0.05[/tex]

Required

Determine the result

Following Charlie's steps:

0.09 is a 2 decimal placed digit

and

0.05 is a 2 decimal placed digit

So, the product is as follows:

9 --------- 2 decimal place

5 --------- 2 decimal place

------------------------------------------

45 --------- 4 decimal place

Shifting the decimals in 45 to 4 decimal places will give us: 0.0045

Hence, the final answer is 0.0045

Answer: A false, B true, C true

Step-by-step explanation:

A) intercept with y axis

That means x=0

y= 3*0-2

y= -2 So A is false

B) intercept with x axis

That means y=0

0= 3x-2

2=3x

2/3= x B is true

C) The form of linear function is

f(x)= mx +n, where m is the slope

In this case m= 3 so C is true

1. The y - intercept is 2. ⇒ False

2. The x - intercept is 2/3 ⇒ True.

3. The slope is 3. ⇒ True.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The function is,

f (x) = 3x - 2

Now,

1. To find the y - intercept we substitute x = 0 in the function.

Hence, The y - intercept is,

f (x) = 0 - 2

f (x) = - 2

Hence, The statement y - intercept is 2 is False.

2. To find the x - intercept we substitute f(x) = 0 in the function.

Hence, The y - intercept is,

f (x) = 3x - 2

0 = 3x - 2

3x = 2

x = 2/3.

Hence, The statement x - intercept is 2/3 is True.

3. We know that;

The slope intercept form of the line is,

y = mx + b

Where, m is slope of the line.

And, b is y - intercept.

So, By comparing with the function f (x) = 3x - 2 , we get;

Slope (m) = 3

Hence, The slope is 3 is True.
