The best prediction of the population in the year 2013 is 3541 based on the fact that the population decreases by 1.4% every year

What is the number of years between 2008 and 2013?

The number of years between 2008 when the population figure was at 3,800 and 2013 is 5 years, hence when determining the population for the year 2013 we need to bear in mind that the population has decreased by 1.4% over a period of 5 years

FV=PV*(1-r)^N

FV= best prediction of the population in the year 2013

PV=population in 2008=3800

r=decreasing rate of the population=1.4%

N=number of years that have passed between 2008 and 2013

FV=3800*(1-1.4%)^5

FV=3541

The required absolute value equation is |x - 87.4| = 1.5

Also,  if the thermometer reads 87.4° F, the least possible temperature is 85.9° F and the greatest possible temperature is 88.9° F

In this question, the thermometer is accurate within 1.5 degrees of the actual temperature in degrees Fahrenheit.

We need to find the least and greatest possible temperature if the thermometer reads 87.4° F

Let x be the temperature in degrees Fahrenheit.

From given information, an absolute value equation would be,

|x - 87.4| = 1.5

We know that, | ±a | = a

x - 87.4 = ±1.5

Case 1: x - 87.4 = 1.5

            x = 1.5 + 87.4

            x = 88.9° F

Case 2: x - 87.4 = -1.5

             x = -1.5 + 87.4

             x = 85.9° F

Therefore, the required absolute value equation is |x - 87.4| = 1.5

Also,  if the thermometer reads 87.4° F, the least possible temperature is 85.9° F and the greatest possible temperature is 88.9° F

The given expression (7 x 10³)(5.4 x 10⁴)/ 9 x 10² as a number in scientific notation is 4.2 × 10^5.

According to the question.

We have an expression (7 x 10³)(5.4 x 10⁴)/ 9 x 10².

Since, we have to write the above expression as a number in scientific notation.

As we know that, scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Thererefore, the expression (7 x 10³)(5.4 x 10⁴)/ 9 x 10² as a number in scientific notation

(7 x 10³)(5.4 x 10⁴)/ 9 x 10²

= (7 × (10^7) × 54)/ 9 × (10^2) × 10

= 7 × 6 × 10^(7 - 3)

= 42 × 10^4

= 4.2 × 10^5

Hence, the given expression (7 x 10³)(5.4 x 10⁴)/ 9 x 10² as a number in scientific notation is 4.2 × 10^5.

Step-by-step explanation:

by bringing all terms to the same fractions (with the same denominator).

so, we have

7

5/7

that means we want to bring both numbers to .../7 form.

7 means 7 whole units.

1 whole unit has now many parts ?

if we aim for 2 parts, that makes 1 whole unit 2/2.

if we aim for 3 parts, 1 whole unit is 3/3.

...

you see, 3/3 = 1/1 = 1.

that is the whole trick.

so, we are looking for 7 parts, and 1 whole unit is 7/7.

now we have 7 whole units.

how many parts are those ?

well, 7 × 7/7 = 49/7

there we go.

we have

7 - 5/7 = 49/7 - 5/7 = 44/7 = 42/7 + 2/7 = 6 2/7

Answer:

x/(1-x)

Step-by-step explanation:

We start by induction. The first 2 terms are x/(1-x^2) and x^2/(1-x^4), respectively. When we add them together using special factorizations, we get: (x^3+x^2+x)/(1-x^4). We quickly realize that the numerator is a geometric series. Applying the following formula, we can simplify our expression to (x^4-x)/(1-x^4)(x-1). Now, we introduce our 3rd term, and add that to our sum. That gets us: (x^7+x^6+...+x)/(1-x^8). This is another Geometric series, and we apply the exact same formula, for this new fraction: (x^8-x)/(1-x^8)(x-1). We realize this is a pattern, and we can utilize this pattern for the sum of the first n terms.
We look at the exponents. For the first 3 terms, the Degree is 8, for the first 2 terms, the Degree is 4. We take note that this looks like x^2^n.

Using that our general formula IS: (attached to this text) (x^2^n-x)/(1-x^2^n)(x-1). Now, when 0<x<1 and n approaches infinity, what do we get?
all terms x^2^n are so small, it's basically redundant, and can be crossed off. This leaves us with -x/(x-1), which can be simplified to x/(1-x).

Applying the same-side-interior angles theorem, the values are:

x = 95°

z = 35

An examples of angles that are referred to as same-side-interior angles are x° and 85°.

According to the same-side-interior angles theorem, the sum of x and 85 will give 180 degrees if lines h and o are parallel to each other.

Since h║o, therefore:

x + 85 = 180

x + 85 - 85 = 180 - 85

x = 95°

(6z - 115)° and x° are vertical angles, therefore:

6z - 115 = x

Plug in the value of x

6z - 115 = 95

6z - 115 + 115 = 95 + 115

6z = 210

6z/6 = 210/6

Answer:

365 x 4 = 1460

Step-by-step explanation:

The area model shows that 365 multiplied by 4 is equal to 18.

First, we draw a rectangle to represent the number 365. We divide it into three parts vertically to represent the digits 3, 6, and 5.

  3       6       5

Next, we draw a rectangle to represent the number 4. We position it to the right of the rectangle for 365.

  3       6       5

                  4

To find the area, we calculate the individual areas of each section and then add them up.

The area of the rectangle representing 3 is 3 times the height, which is 1.

 3       6       5

 |         |         |

 |         |         |

 |         |         |

The area of the rectangle representing 3 is 3.

The area of the rectangle representing 6 is 6 times the height, which is 1.

  3       6       5

 | |       |         |

 | |       |         |

 | |       |         |

The area of the rectangle representing 6 is 6.

The area of the rectangle representing 5 is 5 times the height, which is 1.

  3       6       5

 | | |     |         |

 | | |     |         |

 | | |     |         |

The area of the rectangle representing 5 is 5.

The area of the rectangle representing 4 is 4 times the height, which is 1.

  3       6       5

 | | |     | |     |

 | | |     | |     |

 | | |     | |     |

So, the area of the rectangle representing 4 is 4.

Now, the total area, we add up the areas of the individual sections:

= 3 + 6 + 5 + 4

= 18

Therefore, the area model shows that 365 multiplied by 4 is equal to 18.

The range of the function y = x^2 + 4x + 7 is y >= 3

The equation of the function is given as

y = x^2 + 4x + 7

Start by differentiating the above function

So, we have

y' = 2x + 4

Set the above equation to 0

So, we have

2x + 4 = 0

Divide through the equation by  2

So, we have

x + 2 = 0

Evaluate the like terms:

x = -2

Substitute x = -2 in y = x^2 + 4x + 7

y = (-2)^2 + 4(-2) + 7

Evaluate the expression

y = 3

The leading coefficient of the equation y = x^2 + 4x + 7 is positive
