Logistic growth function with oscillation is a mathematical model that describes the growth of a population that is limited by its resources.

The logistic growth function itself is an S-shaped curve that levels off as the population approaches its carrying capacity. However, when there are additional factors that cause oscillations or fluctuations in the population size, the model can be modified to include periodic behavior.

One example of a logistic growth function with oscillation is the Lotka-Volterra predator-prey model. In this model, the population of predators and prey are linked through a set of differential equations that describe how the two populations interact with each other. The oscillations in this model occur due to the interplay between the predator and prey populations, with each population affecting the growth of the other.

The equation of the red graph include the following: B. f(x) = -x².

In Mathematics and Geometry, the translation of a graph to the right simply means a digit would be added to the numerical value on the x-coordinate of the pre-image:

g(x) = f(x - N)

Conversely, the translation of a graph downward simply means a digit would be subtracted from the numerical value on the y-coordinate (y-axis) of the pre-image:

g(x) = f(x) - N

Since the parent function g(x) = 4 - x² was translated 4 units down in order to produce the graph of the image f(x), we have:

f(x) = g(x) - 4

f(x) = 4 - x² - 4

The more variable the data, the less accurate the sample mean will be as an estimate of the population mean. In statistical analysis, accuracy is important. Statistical analysis is a method of gathering and examining data to uncover useful information.

A sample mean is a numerical estimate that represents a data set's central tendency. The population mean, on the other hand, is a statistical measure that represents the mean value of the entire population. The difference between the two lies in the fact that sample mean is computed on a subset of the population whereas population mean is calculated for the entire population. If the variability of the sample data is large, the sample mean becomes less accurate as an estimate of the population mean.

As a result, the more variable the data, the less accurate the sample mean will be as an estimate of the population mean.Therefore, it is essential to examine the variability of the data in order to better estimate the population mean. The greater the variability in the data, the more difficult it becomes to identify the true population mean and the less accurate the sample mean is as an estimator of the population mean.

Answer: The inequality given is:

250(1.12)^s > 3750

We want to solve for s, the number of years until the number of mice exceeds 3750. We can begin by dividing both sides of the inequality by 250:

(1.12)^s > 15

Next, we can take the logarithm of both sides of the inequality with base 1.12:

log₁.₁₂ [(1.12)^s] > log₁.₁₂ (15)

s > log₁.₁₂ (15)

Using a calculator, we can evaluate the right-hand side to be approximately 6.27. Therefore:

s > 6.27

Since s must be a whole number, we can round up to the nearest integer to get:

s = 7

Therefore, in 7 years the number of mice will exceed 3750.

Answer and Step-by-step explanation:

First, solve for the volume of the sphere, then solve for the height of the cone using the volume of the sphere (which is said to be equal to the volume of the cone) and the radius given.

Volume formula of Sphere

V = \(\frac{4}{3} \pi r^2\)

Substitute 1 in for r

\(\frac{4}{3} \pi (1)^2 = \frac{4}{3} \pi = 4.189\) = Volume

Finding the Height of a Cone

Volume formula for Cone: \(V = \pi r^2\frac{h}{3}\)

Solve for h

Multiply both sides by 3, then divide by pi and r^2.

\(h = \frac{3V}{\pi r^2}\)

Plug in the volume and the radius.

\(h = \frac{3(4.189)}{\pi (1)^2}\)

Simplify

\(h = \frac{12.567}{\pi }\)

h ≈ 4

4 is approximately the height.

Answer:

y = -26

Step-by-step explanation:

[y = 2 - 2x] + [y = -16 + 2(x - 3)^2​]

y = -16 + 2x - 6^2

y = -16 + 2x - 6^2 + 2 - 2x

y = (+2x - 2x) - 16 - 6^2 + 2

y = -16 - 6^2 + 2

y = -16 - 12 + 2

y = - 28 + 2

y = -26

Hence option 1, 2, 3 are the right angle triangle.

The given triangles can be classified according to the Pythagorean theorem.

If the longest side of the triangle is c, and the other two sides are a and b, then the Pythagorean theorem states that

a² + b² = c².

1. Triangle 1: 6, 12, and 13.

The length of sides of the first triangle is 6, 12, and 13.

This triangle is a right triangle as a² + b² = c² can be applied here.

where a = 6, b = 12, and

c = 13.6² + 12²

= 36 + 144 = 18013²

= 169

Hence the triangle is a right triangle.

2. Triangle 2: 5, 12, and 13.

The length of sides of the second triangle is 5, 12, and 13.

This triangle is a right triangle as a² + b² = c² can be applied here

where a = 5, b = 12, and

c = 13.5² + 12²

= 25 + 144 = 16913²

= 169

Hence the triangle is a right triangle.

3. Triangle 3: 3, 4, and 5.

The length of sides of the third triangle is 3, 4, and 5.

This triangle is also a right triangle as a² + b² = c² can be applied here where a = 3, b = 4, and c = 5.

3² + 4² = 9 + 16 = 255² = 25.

Hence the triangle is a right triangle.

4. Triangle 4: 2, 4, and 6.

The length of sides of the fourth triangle is 2, 4, and 6.

This triangle is not a right triangle as a² + b² = c² cannot be applied here where a = 2, b = 4, and c = 6.2² + 4² = 4 + 16 = 20 (not equal to 6² = 36)

Hence the triangle is not a right triangle.

A polynomial function of degree 2 or less that passes through the points (9, 393), (8, 317), and (10, 477), we can use the method of interpolation. The resulting polynomial function is p(x) = 20x^2 - 689x + 6068. The graph of the polynomial function, as well as the graph of y = 1/p(x), can be sketched to visualize the relationship.

To determine the polynomial function of least degree that passes through the given points, we can set up a system of equations using the general form of a polynomial of degree 2 or less: p(x) = ax^2 + bx + c.

By substituting the x and y values of the given points into the equation, we get a system of equations. Solving this system, we find the values of a, b, and c.

Using the method of interpolation, the resulting polynomial function is p(x) = 20x^2 - 689x + 6068.

To sketch the graph of the polynomial function, we can plot the points (9, 393), (8, 317), and (10, 477) on a graph and connect them with a smooth curve representing the polynomial.

The general solution to the given differential equation is\(y = (C_1)/(x(x-6y))\)where C_1 is the constant of integration.

The given differential equation is \(9x(x+y)y'=9y(x-6y)\)

Step 1: We can simplify this equation to get y' and dy/dx by dividing both sides by

9xy(x−6y) = (x−6y)dy/dx + y

=> dy/dx = y/[x(x−6y)] − 1/(x−6y)

Now, we can rewrite the differential equation as dy/dx = y/[x(x−6y)] − 1/(x−6y)

Step 2: This is a separable differential equation.

We can write it in the form

dy/dx + 1/(x−6y) = y/[x(x−6y)] Multiplying by the integrating factor μ(x) = e∫(1/(x−6y))dx gives us

\(\mu(x)dy/dx + [\mu(x)/(x-6y)] = \mu(x)y/[x(x-6y)]\)

We can simplify this as \(d/dx[\mu(x)y] = \mu(x)y/[x(x-6y)]\)

Integrating both sides, we get

ln|y| = ∫μ(x)/(x(x−6y)) dx + C where C is the constant of integration

Step 3: Now, we need to find the integrating factor μ(x). We can writeμ(x) = e∫1/(x−6y) dxSo, we substitute x−6y = t and get dx = dt + 6dy

So,

\(\mu(x) = e\int1/(x-6y) dx\)

= e∫1/t dt

= e^(ln|t|)

= |t|

= |x−6y|

Step 4: Substituting for μ(x) and simplifying the integral, we get

\(ln|y| = -(1/6)ln|x-6y| - (1/6)ln|x| + C'\)

=> \(ln|y| = ln((C_1)/(x(x-6y)))\)

=> \(y = (C_1)/(x(x-6y))\)

Where C_1 = e^C' is a new constant of integration \(y = (C_1)/(x(x-6y))\)

The best choice is: a stratified sample drawn from the market area's cities and towns.

A method of sampling a population that typically divides into smaller groups is called stratified sampling. The term "strata" refers to these groups. For research purposes, the population size may be too large for a researcher to handle, necessitating a significant investment of time and resources. Therefore, the researcher may divide the population into strata of small groups that are simple to manage for convenience.

In a research study, a stratified sample ensures that each subgroup (strata) of a given population is adequately represented within the entire sample population. A sample of adults could be divided into subgroups based on age, such as 18–29, 30–39, 40–49, 50–59, and 60 and older.

The formula for the volume of a hemisphere is (2/3)πr³.

Since the radius of the hemisphere is not given,

Assume it to be the same as the radius of the cone, which is 6 feet.

So, the volume of the hemisphere is,

⇒ (2/3)π(6³) = 144π cubic feet

The formula for the volume of a cone is (1/3)πr²h,

where r is the radius and h is the height.

Put in the values we have, we get,

⇒ (1/3)π(6²)(12) = 144π/3

                        = 48π cubic feet

Find the total volume of the composite solid by adding the volumes of the hemisphere and the cone,

⇒ Total volume = Volume of hemisphere + Volume of cone

⇒ Total volume = 144π + 48π
