The length of side BD is, 40

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In figure,

⇒ AB = 20

⇒ BC = 10

In triangle ABC;

We can find the side AC by using Pythagoras theorem as;

⇒ AB² = AC² + CB²

⇒ 20² = AC² + 10²

⇒ 400 - 100 = AC²

⇒ AC² = 300

⇒ AC = 10√3

Now, By using proportional relationship in triangles ABC and triangle ACD;

⇒ Hypotenuse / Short

⇒ AB / BC = AD / AC

Substitute all the values, we get;

⇒ 20 / 10 = AD/10√3

⇒ 2 × 10√3 = AD

⇒ AD = 20√3

In triangle ACD;

We an find CD by using Pythagoras theorem as;

⇒ AD² = AC² + CD²

⇒ (20√3)² = (10√3)² + CD²

⇒ 1200 - 300 = CD²

⇒ CD² = 900

⇒ CD = 30

Hence, Length of BD is,

⇒ BD = BC + CD

⇒ BD = 10 + 30

⇒ BD = 40

Thus, The length of side BD is, 40

41. MODELING - Wild Mustangs According to the Bureau of Land Management, the wild mustang population of Nevada in 2004 was 2515 more than six times the wild mustang population in Utah. The total number of wild mustangs in Nevada and Utah was 21,730. Determine the number of wild mustangs in each state in 2004.​

Answers

The number of wild mustangs in Utah and Nevada are 2745 and 18985

respectively.

What is a linear equation?

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

From the given information let the number of wild mustangs in Utah be 'x'

So, The number of wild mustangs in Nevada is 6x + 2515.

Therefore, x + 6x + 2515 = 21730.

7x = 21730 - 2515.

7x = 19215.

x = 19215/7.

x = 2745.

So, The number of wild mustangs in Utah is 2745 and hence the number of wild mustangs in Nevada is 6×2745 + 2515 = 18985.

Answers

In this case, with a standard deviation of 8 and a Z-score of 1.96 (which represents the 95th percentile), the interval would be from 85 - (8 * 1.96) to 85 + (8 * 1.96), or approximately 69 to 101.

A normal distribution of standardized test scores with a mean of 85 and a standard deviation of 8 has an approximately 95 percent of scores that fall between two points on the distribution. These points are commonly referred to as the "margin of error" and are used to create a confidence interval around the mean. To find the interval, we use the standard deviation and the Z-score to determine the number of standard deviations away from the mean the interval bounds lie. In this case, with a standard deviation of 8 and a Z-score of 1.96 (which represents the 95th percentile), the interval would be from 85 - (8 * 1.96) to 85 + (8 * 1.96), or approximately 69 to 101.

The matrix M is:

This satisfies the relation [an] = [an-1] * M.

Matrix Diagonalization Sequence An

The matrix M is determined by the recurrence relation. The first row of the matrix represents the coefficients of an and an-1 in the expression for an+1, and the second row represents the coefficients of an-2 and an-3.

Here, in the recurrence relation an+1 = 8an - 2an-1, the coefficient of an is 8 and the coefficient of an-1 is -2, so the first row of the matrix M is [8 -2].

Similarly, the second row of the matrix represents the coefficients of an-2 and an-3 in the expression for an-1. However, in the recurrence relation, there is no explicit expression for an-2 and an-3, so we set them to zero in the second row of the matrix, giving [1 0].

(a) describe the relationship among the lengths of the segments formed by the two secants. you may use words and/or an equation.

Answers

The lengths of the segments formed by two secants are proportional to the distances of the points where the secants intersect the circle from the center of the circle.

If we denote the lengths of the two segments as x and y, and the distance between the center of the circle and the point of intersection of the secants as d, then x/y = d1/d2, where d1 and d2 are the distances between the center and the points of intersection of the secant with the circle.

When two secants intersect a circle at two distinct points, the lengths of the segments formed by the two secants are proportional to the distances between the center of the circle and the points of intersection. This is because the two segments are radii that connect the center of the circle to the points of intersection of the secants with the circle.

The proportionality between the lengths of the segments and the distances from the center can be expressed mathematically as x/y = d1/d2, where x and y are the lengths of the two segments, d1 and d2 are the distances between the center and the points of intersection of the secants with the circle, and x/y represents the ratio of the lengths of the two segments.

So, as the distances from the center to the points of intersection increase, the lengths of the segments will also increase in the same ratio. And if the distances from the center decrease, the lengths of the segments will decrease in the same ratio.

Fill in the blanks to follow the steps in solving the equation:

5x − 12 − 6x = −10x + 7 − 1

Answers

Answer:

see explanation

Step-by-step explanation:

5x - 12 - 6x = - 10x + 7 - 1

step 1 : combine like terms

- x - 12 = - 10x + 6

step 2 : collect x- terms on the left side of the equation

add 10x to both sides

9x - 12 = 6

step 3 : collect constants on the right side of the equation

add 12 to both sides

9x = 18

step 4 : isolate x by dividing both sides by 9

x = 2

Final answer:

To solve the equation 5x - 12 - 6x = -10x + 7 - 1, combine like terms and isolate the x term and we get x=2

Explanation:

To solve the equation 5x - 12 - 6x = -10x + 7 - 1, we need to combine like terms on both sides of the equation. Let's start by combining the x terms on the left side:
(5x - 6x) - 12 = -10x + 7 - 1
Simplifying further:
-x - 12 = -10x + 6
Next, we want to get all the x terms on one side of the equation. We can do this by adding 10x to both sides:
-x - 12 + 10x = -10x + 6 + 10x
Simplifying further:
9x - 12 = 6
Now, we want to isolate the x term. Let's add 12 to both sides:
9x - 12 + 12 = 6 + 12
Simplifying further:
9x = 18
Finally, divide both sides of the equation by 9 to solve for x:
x = 2

The solution of the initial value problem is y = -3x/(3㏑x - 1)

What an initial value problem?

An initial value problem is a differential equation in which the initial value of the function is given.

How to solve the initial value problem?

Since we have the initial value problem

y' = (xy + y²)/x² , y(1) = 3.

We see that it is a homogeneous differential equation.

What is a homogeneous differential equation?

A homogeneous differential equation is a differential equation in which the powers of x and y are the same.

So, we proceed to solve the equation as folows.

Let y = vx.

So,

y/x = v and dy/dx = xdv/dx + v

So, substituting these two into the differential equation, we have that

y' = (xy + y²)/x²

dy/dx = (xy/x² + y²/x²

xdv/dx + v = y/x + (y/x)²

xdv/dx + v = v + v²

xdv/dx = v²

Now using the method of separation of variables, we have that

dv/v² = dx/x

Integrating both sides, we have that

∫dv/v² = ∫dx/x

-v⁻¹ = ㏑x + C

-1/v = ㏑x + C

Substituting v = y/x into the equation, we have that

- 1/y/x = ㏑x + C

-x/y = ㏑x + C

So, making y subject of the formula, we have that

y = -x/(㏑x + C)

Since y(1) = 3, we have that

3 = -1/(㏑1 + C)

3 = -1/(0 + C)

3 = -1/C

C = -1/3

So, y = -x/(㏑x + (-1/3))

y = -x/(㏑x - 1/3)

y = -x/(3㏑x - 1)/3

y = -3x/(3㏑x - 1)

So, the solution is y = -3x/(3㏑x - 1)

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that

ω₁ = 70% ÷ 100% = 0.7; 70% pure antifreeze.

ω₂ = 95% ÷ 100% = 0.95.

ω₃ = 85% ÷ 100% = 0.85.

V₁ = ?; volume of 70% antifreeze.

V₂ = ?; volume of 95% antifreeze.

V₃ = V₁ + V₂.

V₃ = 180 gal.

The quantity will be calculated as:-

V₁ = 180 gal - V₂.

ω₁ · V₁ + ω₂ ·V₂ = ω₃ · V₃.

0.70 · (180 gal - V₂) + 0.95 · V₂ = 0.85 · 180 gal.

Answer:

Option A.

Step-by-step explanation:

Laura and Sean find the product of 3x4 using different methods.
Laura: It's 2 thirds of 4.
²×4 = 3 +
Use words, pictures, or numbers to compare their methods in the space below.
Sean: It's 4 groups of 2 thirds.
2|3
+
= 4x
8
83 this is also worth 100 points

Answers

Both Laura and Sean arrive at the same answer of 8/3 by using different methods.

Laura starts by multiplying 2/3 by 4 to find the total amount of 2/3 in 4 units.

Sean starts by finding the total amount of 2/3 in one group and then multiplying that amount by the number of groups, 4.

Both methods lead to the same answer, so it doesn't matter which method is used. The important thing is that the answer is correct.

What is an inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Dani wants to spend less than 1 hour at the gym.

She will spend 20 minutes lifting weights and then will walk around the indoor track.

It takes her 4.5 minutes to walk around the track.

The number of times that Dani can walk around the track,

< (60 - 40)/4.5

< 40/4.5

< 8.9

Therefore, she can walk around 8 times around the track.

WHICH SYSTEM IS THE SOLUTION OF THE GRAPH?

Answers

The solution to the system of inequalities is following as y ≤ -4 ;y ≤ - x + 4

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

As per option (A), we have the system of inequality as follows:

y ≤ -4

y ≤ - x + 4

The region is above the graph, hence our inequality should be y ≤ - x + 4

The inequality sign part comes from visible the graph, the line is drawn using a dashed line, hence the line is included in the region.

Thus, this graph corresponds to a system of inequalities which is the correct answer that would be option (A).

find the coordinates of point $p$ along the directed line segment $ab$ so that the ratio of $ap$ to $pb$ is $1$ to $3$ .

Answers

The point $p$ has coordinates such that the ratio of the distances $ap$ to $pb$ is $1$ to $3$.

To find the coordinates of point $p$ along the directed line segment $ab$, we will use the ratio of $ap$ to $pb$ being $1$ to $3$. First, we need to find the length of $ap$ and $pb$. To do this, we will use the formula for the distance between two points: [tex]$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$[/tex]. We know the coordinates for points $a$ and $b$, so we can plug them into the formula to find the length of $ab$, which is $d_{ab}$. We can then use the ratio of $1$ to $3$ to find the lengths of $ap$ and $pb$. $d_{ap}=\frac{1}{4}d_{ab}$ and $d_{pb}=\frac{3}{4}d_{ab}$. We can then use the formula for the distance between two points again, this time with the coordinates of $a$ and $p$, to find the coordinates of $p$. Finally, we can plug the coordinates of $p$ back into the formula to check if the ratio of $ap$ to $pb$ is indeed $1$ to $3$.
