Pour résoudre cette expression, nous allons appliquer la distributivité, c'est-à-dire multiplier chaque terme entre parenthèses par le nombre devant les parenthèses.

On commence par 4x + [3 - (7-x)], ce qui donne:

4x + (3 - 7 + x)

Ensuite, nous pouvons appliquer la distributivité à 4x-(x-2):

4x + (3 - 7 + x) - (4x - x + 2)

Enfin, nous pouvons réorganiser les termes pour simplifier l'expression:

4x + 3 - 7 + x - 4x + x - 2

En réarrangeant, nous obtenons:

-2 - 4 + 5x

Donc, l'expression complète est: -2 - 4 + 5x.

In this question, we were given five relations and asked to determine if they are reflexive, symmetric, and/or transitive.

(a) The relation Ri on R is reflexive, symmetric, and transitive.

(b) The relation R on A is not reflexive, not symmetric, and transitive.

(c) The relation Rs on Z is not reflexive, not symmetric, and transitive.

(d) The relation R, on Z is not reflexive, not symmetric, and not transitive.

(e) The relation Rs on Z is reflexive, not symmetric, and transitive.

A reflexive connection is a relationship between items of a set A in which each element is related to itself. As the name implies, the image of each element of the set is its own reflection. In set theory, a reflexive relation is an essential concept.

(a) Ri is reflexive, symmetric, and transitive.

- Reflexive: For any x ∈ R, (x, x) ∈ Ri since |x - x| = 0 < 1.

- Symmetric: For any (x, y) ∈ Ri, we have |x - y| < 1, which implies |y - x| < 1. Therefore, (y, x) ∈ Ri.

- Transitive: For any (x, y), (y, z) ∈ Ri, we have |x - y| < 1 and |y - z| < 1. Adding these inequalities, we get |x - z| < 2, which implies (x, z) ∈ Ri.

(b) R is not reflexive, symmetric, or transitive.

- Not reflexive: For any x ∈ A, (x, x) ∉ R since x - x = 0 is not a positive integer.

- Not symmetric: For any distinct x, y ∈ A, if (x, y) ∈ R, then x - y = 1, which implies y - x = -1 is not a positive integer. Therefore, (y, x) ∉ R.

- Not transitive: Let A = {1, 2, 3} and R = {(1, 2), (2, 3)}. Then (1, 3) is not in R since 3 - 1 = 2 is not a positive integer.

(c) R3 is not reflexive, symmetric, or transitive.

- Not reflexive: For any x ∈ Z, (x, x) ∉ R3 since x * x = x^2 is not greater than 0.

- Symmetric: For any (x, y) ∈ R3, we have xy > 0, which implies yx > 0. Therefore, (y, x) ∈ R3.

- Not transitive: Let x = -1, y = 2, and z = -1. Then (x, y) ∈ R3 and (y, z) ∈ R3, but (x, z) = (-1, -1) ∉ R3 since xz = 1 is not greater than 0.

(d) R, is not reflexive, symmetric, or transitive.

- Not reflexive: For any y ∈ Z, (y, y) ∉ R, since 3 does not divide y + 2y = 3y.

- Not symmetric: For y = 1 and z = 2, we have (2, 1) ∉ R, but (1, 2) ∈ R since 3 divides 1 + 4 = 5.

- Not transitive: Let x = 2, y = 1, and z = 5. Then (x, y) ∈ R, (y, z) ∈ R, but (x, z) = (2, 5) ∉ R since 3 does not divide 2 + 10 = 12.

(e) Rs is the relation on Z given by Rs = {(x,y) ⬠Zx Z: there exists k ⬠N such that elyk and yak).

- Reflexive: This relation is not reflexive because (1, 1) ∉ Rs as there does not exist k such that 1 x k = 1.

- Symmetric: This relation is not symmetric because, for example, (1, 2) ∈ Rs but (2, 1) ∉ Rs since there does not exist k such that 2 x k = 1.

- Transitive: This relation is not transitive. For example, let x = 1, y = 2, and z = 4. Then (x, y) ∈ Rs and (y, z) ∈ Rs, but (x, z) ∉ Rs since there does not exist k such that 1 x k = 4.

In short, in this question, we were given five relations and asked to determine if they are reflexive, symmetric, and/or transitive.

(a) The relation Ri on R is reflexive, symmetric, and transitive.

(b) The relation R on A is not reflexive, not symmetric, and transitive.

(c) The relation Rs on Z is not reflexive, not symmetric, and transitive.

(d) The relation R, on Z is not reflexive, not symmetric, and not transitive.

(e) The relation Rs on Z is reflexive, not symmetric, and transitive.

122.08 pounds

Step-by-step explanation:

After using the limit definition of the derivative, the answer comes as 6x.

The function is f(x) = 3x² - x + 1.

We have to find the derivative of the function using the limit definition of the derivative, f'(x) = limax-0 f( x+ Ax )-f(a).

So, we know that the limit definition of the derivative, f'(x) = limax-0 f(x+ Ax)-f(a) / Ax

By substituting the given values in the above formula, we get; f'(x) = lim Ax-0 {f(x + Ax) - f(x)} / Ax

Now, let us find the derivative of the given function.

Substitute the values in the above formula; f'(x) = lim Ax-0 {f(x + Ax) - f(x)} / Axf'(x) = lim Ax-0 {[3(x + Ax)² - (x + Ax) + 1] - [3x² - x + 1]} / Axf'(x) = lim Ax-0 {[3(x² + 2xAx + A²) - x - Ax + 1] - [3x² - x + 1]} / Axf'(x) = lim Ax-0 {[3x² + 6xAx + 3A² - x - Ax + 1] - [3x² - x + 1]} / Axf'(x) = lim Ax-0 {[6xAx + 3A²] / A}f'(x) = lim Ax-0 {6x + 3Ax}f'(x) = lim Ax-0 {6x} + lim Ax-0 {3Ax}f'(x) = 6x + 0f'(x) = 6xTherefore, the derivative of f(x) = 3x² - x + 1 is f'(x) = 6x.

Answer: \(\$ 713.84\)

Step-by-step explanation:

Given

The price of a chainsaw is \(\$539.95\)

The price of each safety chaps is \(\$69.95\)

Total price before sales tax

\(\Rightarrow C=539.95+2\times 69.95\\\Rightarrow C=\$ 679.85\)

with a tax of 5%, the total cost will be

\(\Rightarrow C_t=1.05C\\\Rightarrow C_t=1.05\times 679.85=\$ 713.84\)

Using the standard z table, a 95% confidence interval for p is (0.5327,0.6173).

In the given question,

A poll is taken in which 302 out of 525 randomly selected voters indicated their preference for a certain candidate.

We have to find a 95% confidence interval for p.

From the question, x=302, n=525

So estimation point,

P=x/n

P=302/525

P=0.575

Now the z value of 95% confidence interval is 1.960 using the standard z table.

Margin of Error (E)=z×√{P(1−P)}/n

Now putting the value

E=1.960×√{0.575(1−0.575)}/525

E=1.960×√(0.575×0.425)/525

E=1.960×√0.244/525

E=1.960×√0.000465

E=1.960×0.0216

E=0.0423

At 95% confidence interval for p is

P−E ≤ p ≤ P+E

Now putting the value

0.575−0.0423≤ p ≤0.575+0.0423

0.5327≤ p ≤0.6173

Hence, a 95% confidence interval for p is (0.5327,0.6173).

Answer:

x = 15

Step-by-step explanation:

\((\sqrt{4(x -5}) ^{2}\) = 40  If you square the square root of something, it would end up being itself.

4(x - 5) = 40

4x - 20 = 40  Add 20 to both sides

4x = 60  Divide both side by 4

x = 15

Answer:

\(\sqrt{4}(x-5)^2=40 \implies x=5 +2 \sqrt{5}, \quad x=5-2 \sqrt{5}\)

\(\sqrt{4(x-5)^2}=40 \implies x=-15, \quad x=25\)

Step-by-step explanation:

Given equation:

\(\sqrt{4}(x-5)^2=40\)

Simplify  √4 = 2 :

\(\implies 2(x-5)^2=40\)

Divide both sides by 2:

\(\implies (x-5)^2=20\)

Square root both sides:

\(\implies x-5=\pm \sqrt{20}\)

Simplify the right side of the equation:

\(\implies x-5=\pm \sqrt{4 \cdot 5}\)

\(\implies x-5=\pm \sqrt{4} \sqrt{5}\)

\(\implies x-5=\pm 2 \sqrt{5}\)

Add 5 to both sides:

\(\implies x=5 \pm 2 \sqrt{5}\)

Therefore, the solutions are:

---------------------------------------------------------------------------------------

Given equation:

\(\sqrt{4(x-5)^2}=40\)

Square both sides:

\(\implies 4(x-5)^2=1600\)

Divide both sides by 4:

\(\implies (x-5)^2=400\)

Square root both sides:

\(\implies x-5=\pm \sqrt{400}\)

\(\implies x-5=\pm 20\)

Add 5 to both sides:

\(\implies x=5-20=-15\)

\(\implies x=5+20=25\)

Therefore, the solutions are:

The Theoretical yield of solid precipitate is 1.42g/mol

Now, consider solid precipitate as cacl2

let us take the mass of cacl2 and calculate the moles of cacl2.

Mass of CaCl2 =2.0 g

By, default the molar mass of CaCl2 =110.98 g/mol

To calculate the Moles we have a formula:

Moles=Given mass*1 mol/Molar mass of a precipitate.-----(1)

substitute the values in equation (1)

Moles of CaCl2 =2.0 g * 1 mol/110.98g

                           = 0.018 mol

Take another solid precipitate:

Mass of K2Co3=2.0 g

The molar mass of K2Co3 =138.205 g/mol

Now calculating the moles of K2Co3

substitute the values in equation(1)

Moles of K2Co3 =2.0 g * 1 mol/ 138.205g

                             =0.0145 moles

According to balanced equation 1mole of CaCl2 reacts with 1 mole of K2CO

Thus, 0.018 moles of CaCl2 will react with 0.018 moles of K2CO3

And,0.0145 moles of K2CO3 will produce 0.0145 moles of CaCO3

Molar mass of CaCO3 =100.0869 g/mol

Theoretical yield of CaCO3 =moles of CaCO3 *molar mass of CaCO3

                                                =0.0145 moles * 100.0869 g/mol

                                                 =1.45g/mol

The area of the triangle ABC is 6 square centimeters.

To find the area of the triangle, we can use Heron's formula, which is based on the lengths of the triangle's sides. Heron's formula states that the area (A) of a triangle with side lengths a, b, and c can be calculated using the following formula:

A = √(s(s-a)(s-b)(s-c))

where s is the semi-perimeter of the triangle, calculated as:

s = (a + b + c) / 2

In this case, the side lengths are given as a = 4 cm, b = 5 cm, and c = 3 cm.

Calculating the semi-perimeter:

s = (4 + 5 + 3) / 2 = 6 cm

Using Heron's formula:

A = √(6(6-4)(6-5)(6-3))

= √(621*3)

= √(36)

= 6 cm²

Therefore, the area of triangle ABC is 6 square centimeters.
