The area that the forest would occupy after 7 years is 2288 km²

An equation is an expression showing the relationship between numbers and variables.

Let y represent area of the forest after x years.

y = abˣ

a is the initial value and b is the multiplication factor.

A certain forest covers an area of 3400 km², hence a = 3400 km². The area decreases by 5.5%, hence b = 100% - 5.5% = 94.5%. Hence:

y = 3400(0.945)ˣ

After 7 years:

y = 3400(0.945)⁷ = 2288 km²

The area of the forest after 7 years is 2288 km²

Answer:

y=-3x+4

Step-by-step explanation:

If we use rise over run from one point to the next, you will see that you rise vertically 3 units, then run horizontally 1 unit.

Then Make the rise negative because this is a negative graph. So -3/1

Divide -3 by 1. -3/1=-3. mx=-3

Now we have to find the y-intercept. This is where the graph crosses/intersects the y-axis. As if you look at the y-axis, you will see that the graph intersects the y-axis at (0,4).

So your y-intercept is 4. b=4.

The orthogonal trajectories for the family of curves 3x^2 − y^2 = C are circles with the equation x^2 + y^2 = C/3.

To find this, we can take the derivative of the original equation 3x^2 − y^2 = C with respect to x, which will give us 6x. Then, we can take the negative reciprocal of this derivative, which is -1/6x. This is the slope of the orthogonal trajectories.

We then can use the point-slope form of a line to get y - y1 = -1/6x (x - x1). Since the slope of the orthogonal trajectories is always -1/6x, we can just set the equation y - y1 = -1/6x (x - x1) equal to 0 and solve for x to get x1 = -y1/6.

We can then plug this value back into the point-slope equation to get y - y1 = -1/6(-y1/6) (x - (-y1/6)), which simplifies to y - y1 = y1/6 + x. Now, if we let y1 = -C/3, then we get y - (-C/3) = C/6 + x, which can be rewritten as x^2 + y^2 = C/3.

Therefore, the orthogonal trajectories for the family of curves 3x^2 − y^2 = C are circles with the equation x^2 + y^2 = C/3.

To find out how many bricks are needed to make the wall, we need to find the total area of the wall and divide it by the area of one brick.

The area of the wall is:

length x height x width = 10 m x 1 m x 0.5 m = 5 m^2

The area of one brick is:

10 cm x 10 cm x 20 cm = 2000 cm^3

To convert the area of the wall from square meter to cubic centimeter, we need to multiply it by 100*100 = 10000.

5 m^2 x 10000 = 50000 cm^2

Now we can divide the total area of the wall by the area of one brick to find out how many bricks are needed:

50000 cm^2 / 2000 cm^2/ brick = 25 bricks

So, 25 bricks will be needed to make the wall.

The measure of the missing angle in a triangle is C = 18°.

An acute angle is one that is 45 degrees. It is a 90-degree angle or half of a right angle. Look at the illustration of the 45-degree angle. Angles are expressed in degrees or radians.

A straight angle is one in which the two arms extend in precise opposition to one another. A 180° angle is a straight angle. A protractor can be used to measure angles; a straight angle is an angle that is measured at 90 degrees.

The two arms are perpendicular to one another at a right angle. Each angle measures 45° when the right angle is divided into two equal pieces. An acute angle is one that is 45 degrees. It is a 90-degree angle or half of a right angle.

Given one of the angles A = 45°

And B is 65% of the total angle sum = 65/100 × 180

                                                             = 117°

For angle C, using angle sum property

⇒ A + B + C = 180°

⇒ 45° + 117° + C = 180°

⇒ C = 180° - (45° + 117°)

⇒ C = 180° - 162°

On solving the equation, it is seen that about 12 ounces of the 15% solution must be mixed with about 6 ounces of the 6% solution to get 18 ounces of the 12% perfume.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Let x = number of liters of the 15% solution

Let 18 − x = number of liters of the 6% solution

Solution Ounces Strength Amount of Perfume

15%         x            15            15x

6%          18 - x      6             6(18 - x)

Mixture   18           12            (18)(12)

So, the equation will be -

(amount of perfume in 15% solution) + (amount of perfume in 6% solution) = (amount of perfume in mixture)

15x + 6(18 − x) = (18)(12)

Solve the equation using distributive property -

15x + 108 - 6x = 216

Combine the like terms -

15x - 6x = 216 - 108

Simplify the equation further -

9x = 108

x = 108/9

x = 12

Now, substituting the value of x in 18 − x = 18 - 12 = 6.

Therefore, the amount in ounces is obtained as 12 ounces and 6 ounces.

In mathematics, an angle is a figure made up of two rays that share a terminal and are referred to as the sides of the angle and the vertices of the angle, respectively.

Angles, which are frequently expressed in terms of degrees or radians, are used to quantify the size of turns.

The law of cosines, the law of sines, and the Pythagorean theorem are only a few examples of mathematical equations that use angles, which are a key component of geometry.

When understanding shapes, angles are equally crucial.

The angles within a triangle, a quadrilateral, and a polygon can provide information on the number of sides a shape has in addition to whether or not it is regular.

Angles are also used to calculate the arcs and circles of an object.

Answer:

63

Step-by-step explanation:

Consecutive odd integers increase by the addition of 2 therefore if the smallest value is x then the next odd number is x + 2

So therefore; x + x + 2 + x + 4 + x + 6 = 264

Collect like terms

x + x + x + x + 2 + 4 + 6 = 264

4x + 12 = 264

4x = 264 - 12

4x = 252

Divide both sides by 4

x = 63

Therefore the smallest of the four consecutive integers is 63

A triangle is a polygon with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified by their sides (such as equilateral, isosceles, or scalene) or by their angles (such as acute, right, or obtuse).

The set of lengths (3,4,5) will create a triangle. This is because it follows the "triangle inequality theorem" which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

The set of lengths (10, 20, 30) will not create a triangle. This is because 10 + 20 is less than 30, so it does not satisfy the triangle inequality theorem.

The set of lengths (15.5, 45, 20.5) will not create a triangle. This is because 15.5 + 20.5 is less than 45, so it does not satisfy the triangle inequality theorem.

Hence,

a. (3, 4, 5) will create a triangle.

b. (10, 20, 30) will not create a triangle

c. (15.5, 45, 20.5) will not create a triangle.

The graph in the upper left corner best shows the population size of a K-selected species over time in a stable environment.

This graph shows the population of the species increasing at a slow rate until it reaches the carrying capacity of the species (the dashed line). After reaching the carrying capacity, the population of the species remains relatively stable, fluctuating slightly around the carrying capacity. This is evidence of a K-selected species, which tend to have a higher carrying capacity and longer life spans, and the population size remains relatively stable over time in a stable environment. Mathematically, this can be expressed as y = K = C, where y is the population size, K is the carrying capacity, and C is the constant value of the carrying capacity.

The ODE's general solution has real solution and complex eigen functions. Typical trajectories are sinusoidal curves.

The general solution of the ODE involves complex eigenfunctions, which are solutions of the form e^(ikx), where k is a real number and i is the imaginary unit. By combining these complex eigenfunctions with real coefficients, a general real solution can be obtained. Typically, these solutions will take the form of sinusoidal curves, with the amplitude and period determined by the coefficients of the eigenfunctions. The coefficients can be determined using initial conditions, allowing for more specific trajectories to be determined. For example, if the initial condition is known, then the coefficients of the eigenfunctions can be determined using Fourier analysis, allowing for the trajectory of the system to be determined.
