Answer:

The set \(S\) of non-negative integers in the inequality \(2x < 4\) is

\(S = \{0, 1\}\)

Step-by-step explanation:

The non-negative integers are given as \(\mathbb{Z}_{\ge 0} = \{ 0, 1, 2, \ldots \}\)

For the inequality \(2x < 4\), we have

\(2x < 4 \implies x < \dfrac{4}{2} \implies x < 2\)

Therefore,

\(x\in \mathbb{R}:x\in(\infty, 2)\)

Note: 2 is not included

The integers are

\(\ldots -2, -1, 0, 1\)

And the non-negative integers are

\(0, 1\)

Answer:

C. 49.

Step-by-step explanation:

The measure of the angle below <1 = 68 degrees (vertical angles).

m < 3 = 72 + 68         External angle of a triangle theorem.

m < 3 = 140

3x - 7 = 140

3x = 147

x = 49.

Answer:

C

Step-by-step explanation:

The angle at the top of the triangle is vertical to ∠ 1 and congruent

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 3 is an exterior angle of the triangle, then

3x - 7 = 72 + 68 = 140 ( add 7 to both sides )

3x = 147 ( divide both sides by 3 )

x = 49 → C

Answer:

(13, 16)

Step-by-step explanation:

Point A has coordinates (3,2) Point b has the coordinates (27,30)

Therefore the width of the diagram = 27 - 3 = 24 units and the height of the diagram = 30 - 2 = 28 unit

The length of the square = 28 unit / 4 square = 7 unit

Also, half of the height of the diagram = 28/2 = 14 unit

Therefore the x coordinate is given by:

27 - (2 × 7) = 27 - 14 = 13 or 27 - 14 (=13) or 3 + 7 + (24 - 3 × 7) = 13

Also, the y coordinate is given by:

30 - (2 × 7) = 30 - 14 = 16 or 30 - 14 (=16) or (30 + 2)÷2 = 16

Therefore the coordinate for point C is given by (13, 16)

Hello!

1 US dollar = 19.92 Mexican Pesos​

$8,25 = 19,92 * 8,25 =>164,34 Mexican Pesos​

Answer:

164.34 Pesos

Step-by-step explanation:

What we know is that 1 USD equals 19.92 Pesos

You have 8.25 USD, just multiply 8.25 by 19.92.

You should get 164.34.

Answer:  The correct answer is x = 19 / 5

Step-by-step explanation:

Solve the equation

5x + 3 = 22

Subtract 3 from both sides

5x + 3 − 3 = 22 − 3

5x = 19

Divide both sides by 5

5x/5 = 19/5

x = 19 / 5

a. The explanatory variable in this study is insomnia and the response variable is the likelihood of experiencing heart problems. b. Amount of caffeine consumed could be a confounding variable in this study because it fits the two properties of confounding variables.

In this study, the explanatory variable is "insomnia" and the response variable is "heart problems." A confounding variable, such as "amount of caffeine consumed," might affect the relationship between insomnia and heart problems. Caffeine consumption fits the two properties of confounding variables as it is related to both the explanatory variable (insomnia) and the response variable (heart problems). Consuming more caffeine can lead to insomnia, and it can also increase the risk of heart problems independently. Therefore, caffeine consumption could be a confounding variable in this study, potentially influencing the observed relationship between insomnia and heart problems.

Answer: 6a³ + a² - 7

Step-by-step explanation:

(5a³ + 4a² − 3a + 2) + (a³ − 3a² + 3a − 9)=

5a³ + a³ + 4a² − 3a² - 3a + 3a + 2 - 9=

6a³ + a² - 0 - 7 = 6a³ + a² - 7

Answer:

6a³ + a²-7

Step-by-step explanation:

1. Get rid of the parentheses by distributing them.

(5a³ + 4a² − 3a + 2) + (a³ − 3a² + 3a − 9) = 5a³ + 4a² − 3a + 2 + a³ − 3a² + 3a − 9

2. Add like-terms.

5a³ + 4a² − 3a + 2 + a³ − 3a² + 3a − 9 = 6a³ + a²-7

Based on the given set of coordinates pairs, we can draw a diagram to show the domain and the range.

Once we defined the domain and range sets, we noticed that there are to domain values 13 and 1 assigned with one range value 54, that relation violates the function definition.

For the three random tosses, there are only 4 potential values out of 8 possible combinations.

The sample space for W is thus:

HHH, W = 3-0 = 3

HHT, W= 2-1=1

HTH, W= 2-1=1

THH, W=2-1 =1

HTT, W= 1-2=-1

THT, W= 1-2=-1

TTH, W=1-2=-1

TTT, W=0-3 = -3

In this instance, W is defined as the random variable that captures the difference between the number of heads and tails in three coin flips.

W = the number of heads minus the number of coins.

We have 3 coin tosses, which gives us 2*2*2=8 outcomes. The outcomes and accompanying values for W can be listed as follows:

HHH, W = 3-0 = 3

HHT, W= 2-1=1

HTH, W= 2-1=1

THH, W=2-1 =1

HTT, W= 1-2=-1

THT, W= 1-2=-1

TTH, W=1-2=-1

TTT, W= 0-3 = -3

After pouring some water from container A into container B, the new height of the water in both containers will be equal.

When container A is filled with water to the brim, it reaches its maximum capacity. Let's assume the initial height of the water in container A is h.

When some water is poured from container A into container B, the water level in both containers will gradually equalize until they reach the same height. Let's denote this new height as H.

The reason the water levels equalize is due to the principle of fluid equilibrium. When the containers are connected and the water is allowed to flow, the water seeks a common level. This occurs because the pressure at the same height in a fluid is equal.

Therefore, after pouring water from container A to container B, the final height of the water in both containers will be H, which indicates that the water has reached an equilibrium point where the pressure is equal in both containers.

Polynomial identities are mathematical expressions that are true for all values of the variables involved.

Polynomial identities play a fundamental role in algebra and can be used to solve problems, prove mathematical statements, and describe numerical relationships. These identities are equations that hold true for any values of the variables involved. For example, the polynomial identity (a + b)^2 = a^2 + 2ab + b^2 is valid for all values of a and b. By using polynomial identities, we can simplify expressions, factorize polynomials, solve equations, and establish connections between different mathematical concepts.

Polynomial identities provide a powerful tool for proving mathematical statements. By manipulating and rearranging expressions using these identities, we can demonstrate the validity of various mathematical relationships. These identities also help us describe numerical relationships, such as the patterns and properties of polynomial functions. By applying polynomial identities, we can analyze the behavior of polynomials, determine the roots or zeros of functions, identify symmetry properties, and investigate the interactions between coefficients and variables. Polynomial identities serve as the building blocks for algebraic reasoning and provide a framework for understanding and exploring the intricate structures of polynomial expressions and equations.

Answer: 2021

Step-by-step explanation:

At the instant when x=4 and y=3, (dx/dt) ≈ 0.143.  We are given the rates of change of z and x with respect to t, and a relationship between x and y, but we are not given the rate of change of y with respect to t.

However, we can use the relationship between x, y, and z to find an expression for (dy)/(dt).

From the hint, we have:

z^2 = x^2 + y^2

Differentiating both sides with respect to t, we get:

2z(dz/dt) = 2x(dx/dt) + 2y(dy/dt)

Simplifying and dividing by 2, we get:

z(dz/dt) = x(dx/dt) + y(dy/dt)

Substituting the given values of (dz)/(dt) and (dx)/(dt), we have:

z = sqrt(x^2 + y^2)

(dz/dt) = 1

(dx/dt) = (3(dy/dt))/t

At the instant when x=4 and y=3, we have:

z = sqrt(4^2 + 3^2) = 5

(dx/dt) = (3(dy/dt))/t

To find (dy/dt), we substitute into the expression we derived earlier:

z(dz/dt) = x(dx/dt) + y(dy/dt)

5(1) = 4(3(dy/dt))/t + 3(dy/dt)

5 = (12/t + 3)(dy/dt)

(dy/dt) = 5/(12/t + 3) = 5t/(12t + 36) = (5/12)(t/(t + 3))

Substituting this into the expression for (dx/dt), we get:

(dx/dt) = (3(dy/dt))/t = (3/12)(t/(t + 3)) = (1/4)(t/(t + 3))

At the instant when x=4 and y=3, we have:

(dx/dt) = (1/4)(4/(4 + 3)) = 1/7

Therefore, at the instant when x=4 and y=3, (dx/dt) ≈ 0.143.

The solution to the compound inequality is x > -3. The correct option is the third option x > -3

From the question, we are to solve the given compound inequality

2x - 2 > -8 or -4x ≤ -36

Solving the first inequality

2x - 2 > -8

Add 2 to both sides of the inequality

2x -2 + 2 > -8 + 2

2x > -6

Divide both sides by 2

2x/2 > -6/2

x > -3

Solving the second inequality

-4x ≤ -36

Divide both sides of the inequality

-4x/-4 ≤ -36/-4

x ≥ 9

From the two solutions, we can conclude that x > -3
