After 31 years the population will be the same. Their populations will be 2072 when they are the same.

Growth rates are calculated by dividing the difference between the ending and beginning values for the period under consideration by the starting value. The most common time periods for growth rates are annually, quarterly, monthly, and weekly.

The formula for the growth of the population is:

A = P(1+r)^n

A is the total number population after n years.

P is the initial number of population

r is rate of interest.

For town A,

The initial population is 700. The growth rate is 3.5% = 0.035.

The population of town A after t year is y = 700(1+0.035)^t

For town B,

The initial population is 1400. The growth rate is 1.25% = 0.0125.

The population of town A after t year is y = 1400(1+ 0.0125)^t

The system of equations is:

y = 700(1+0.035)^t

y = 1400(1+ 0.0125)^t

The intersection point is (31.537,2071.432).

Step-by-step explanation:

Answer: 14

Step-by-step explanation:

f(-2) means x is -2, so we can solve for when x = -2 by plugging -2 into the equation.

[tex]f(-2) = 3(-2^{2}) - (-2)\\=3(4) + 2\\=12+2\\=14[/tex]

Answer:

Step-by-step explanation:

So what you start with is the variable "x" in 3 different places. When you are changing the x variable, you need to plug it into every variable in the equation. Start by doing that and the problem will look like: f (-2) = 3 (-2)^2 - (-2) Now you can start with either the 3 (-2)^2 or the - (-2), but it is better to go from left to right.

The smallest of the consecutive numbers is 495

From the question, we have the following parameters that can be used in our computation:

Mathematical statement

The mathematical statement is given as

The sum of four consecutive multiples of 11 is 2046

The smallest mulitple of 11 is represented by 11x

Where x is an integer greater than 0

This means that the other numbers are 11(x + 1), 11(x + 2) and 11(x + 3)

When represented as an equation, we have

11x + 11(x + 1) + 11(x + 2) + 11(x + 3) = 2046

Evaluate the like terms

44x = 2046 - 66

So, we have

44x = 1980

Divide through by 44

x = 45

The smallest is then calculated as

Smallest = 11 * 45

Evaluate

Smallest = 485

Hence, the smallest of the numbers is 495

[tex]$\boxed{(c) : 11}$[/tex]

Step-by-step explanation:

We can think of this problem as placing $7$ dividers (representing the boys) in $20$ slots (representing the people). Thus, the number of ways to arrange the boys and girls is the number of ways to place the dividers, which is $\binom{20}{7}$.

To find the average value of $S$, we need to find the total number of arrangements where $S = k$ for each possible value of $k$, then divide by the total number of arrangements.

Let's first consider the case where $k=0$. There is only $1$ way to arrange the boys and girls such that there are no boys and girls standing next to each other: BBBBBBBBBBBBBBBBBBBBB.

Next, let's consider the case where $k=1$. There are $\binom{7}{1}\binom{13}{6}$ ways to arrange the boys and girls such that there is exactly $1$ pair of boys and girls standing next to each other. To see this, consider that there are $\binom{7}{1}$ ways to choose the position of the divider that separates a boy and a girl, and $\binom{13}{6}$ ways to arrange the remaining dividers and slots.

We can continue this process to find the total number of arrangements for each possible value of $k$. When we add up all of these arrangements and divide by the total number of arrangements, we get the average value of $S$.

More specifically, the average value of $S$ is equal to

[\frac{1\cdot1+\binom{7}{1}\binom{13}{6}\cdot1+\binom{7}{2}\binom{13}{5}\cdot2+\binom{7}{3}\binom{13}{4}\cdot3+\binom{7}{4}\binom{13}{3}\cdot4+\binom{7}{5}\binom{13}{2}\cdot5+\binom{7}{6}\binom{13}{1}\cdot6+\binom{7}{7}\binom{13}{0}\cdot7}{\binom{20}{7}}.]

Simplifying this expression gives us $\boxed{(c) : 11}$.

Therefore , As a result 5, 10, and 15 make up the reasonable domain for the function 2 (l + w) = 64..

A connection between a group of sources and one output for each input is referred to as a function. A function is, to put it simply, a collection of equation  connected to a single, unique output. In mathematics, a function is a statement, rule, or law that describes the connection between two variables (the dependent variable). One input leads to one output when a rule of this type is used. by Alex Federspiel, the photographer. This statement gives an example of y=x2. There is just one output for y from any input for x. According to our definition, y is a function of x since x is the input value.

We must determine the length and breadth values necessary to make the rectangle's perimeter 64.

Answer:

  6.08 fluid ounces

Step-by-step explanation:

You want the amount of stain required to cover the surface area of the ends and three sides of a beam 6" square and 6 ft long. 128 floz of stain will cover 200 square feet.

The two ends of the beam are 1/2 ft square, so the area of each is ...

  A = s² = (1/2 ft)² = 1/4 ft²

The two ends have a total area of ...

  2 × (1/4 ft²) = 1/2 ft² . . . . end area

Three of the four sides of the beam are to be stained, so their total area is the area of 3 rectangles, each of which is 1/2 ft by 6 ft.

The area of each rectangle is ...

  A = LW

So, the area of the three rectangles is ...

  total side area = 3 × (1/2 ft)(6 ft) = 9 ft²

Then the area to be stained is the sum of the end area and the side area:

  stained area = (1/2 ft²) +(9 ft²) = 9.5 ft²

The amount of stain required is proportional to the area, so we can write the proportion ...

  q/(9.5 ft²) = (128 floz)/(200 ft²)

Multiplying by 9.5 ft² gives ...

  q = (128 floz)(9.5/200) = 6.08 floz

The homeowner needs 6.08 fluid ounces of stain to stain the beam.

Add

9 + 5/6

Write as a mixed number

9 5/6

Answer:

9 and 5/6

Step-by-step explanation:

We can start by adding 5 + 4 which equals 9

Then we add 1/2 to 1/3

Both these numbers can be changed to one with the same denominator

So, 1/2 = 3/6 and 1/3 = 2/6

= 3/6 + 2/6

= 5/6

Add 5/6 back to the 9 we got earlier, we get 9 5/6

Answer:

0 ≤ n ≤ 5

Step-by-step explanation:

We have the function for growth as
[tex]g(n) = 10(1.02)^n[/tex]

We also know that after a specific n days, the flower has grown to 11.04 inches

Since g(n) represents the height of the flower, we can substitute 11.04 for g(n) and solve for n

∴We get

[tex]11.04 = 10(1.02)^n[/tex]

Switching sides we get

[tex]10(1.02)^n = 11.04[/tex]

Divide both sides by 10 to get

[tex]1.02^n = 1.104[/tex]

Take log on both sides

[tex]\log(1.02^n) = \log(1.104)[/tex]

[tex]\log(x^a) = a \log(x)[/tex]

So

[tex]\log(1.02^n) = n \log(1.02)[/tex]

Therefore

[tex]n \log(1.02) = \log(1.104)[/tex]

[tex]n = \dfrac{\log(1.104)}{\log(1.02)}[/tex]

Using a calculator this works out to

[tex]n = 4.9963[/tex]

Therefore it takes at least these many days for the flower to reach 11.04 inches

Rounding number of days to 5, we get the right side of the inequality as n ≤ 5

n cannot be negative so it starts of with a value of 0 so on the right side of the inequality we get n ≥ 0 which can be rewritten as 0 ≤ n

Together the domain of n can be represented as

0 ≤ n ≤ 5

To get the percentage of those who love outdoor activities as well as non-fiction, we must complete the table.

Given:

Total number of those who love Fiction and Non Fiction but who love indoors = 50

From that list those who love fiction = 24, thus, those who love indoor and non-fiction =

50 - 24 = 26

Total number of those who were served are = 90

If the total number of those who love Fiction and Non-Fiction but who love indoors = 50

Then the total number of those who love Fiction and Non Fiction but who love Outdoors = 90 - 50 = 40

If the total number of those who love outdoor (Fiction and non-fiction) = 40 and those who prefer fiction only from this category is = 30;
