Taking into account the definition of molarity, 14.028 grams of sodium chloride must be added to make 400 mL of a 0.600 M sodium chloride.

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case, you know:

Replacing in the definition of molarity:

[tex]0.600 M=\frac{number of moles}{0.400 L}[/tex]

Solving:

number of moles= 0.600 M× 0.400 L

number of moles= 0.24 moles

Being the molar mass of sodium chloride 58.45 [tex]\frac{g}{mole}[/tex], that is the amount of mass that a substance contains in one mole, the mass of sodium chloride can be calculated as:

0.24 moles×58.45 [tex]\frac{g}{mole}[/tex]= 14.028 grams

Finally, 14.028 grams of sodium chloride must be added to make 400 mL of a 0.600 M sodium chloride.

The expression [tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx[/tex]  is an illustration of definite integrals

The approximated value of the definite integral is 0.0059

The definite integral is given as:

[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx[/tex]

For arctan(x), we have the following series equation:

[tex]\arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 1}}{2n + 1}}[/tex]

Multiply both sides of the equation by x^3.

So, we have:

[tex]x^3 * \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 1}}{2n + 1}} * x^3[/tex]

Apply the law of indices

[tex]x^3 * \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 1 + 3}}{2n + 1}}[/tex]

[tex]x^3 * \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}}[/tex]

Evaluate the product

[tex]x^3 \arctan(x) = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}}[/tex]

Introduce the integral sign to the equation

[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =\int\limits^{1/2}_{0} \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}}[/tex]

Integrate the right hand side

[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =[ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{x^{2n + 4}}{2n + 1}} ]\limits^{1/2}_{0}[/tex]

Expand the equation by substituting 1/2 and 0 for x

[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =[ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{(1/2)^{2n + 4}}{2n + 1}} ] - [ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{0^{2n + 4}}{2n + 1}} ][/tex]

Evaluate the power

[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx =[ \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{(1/2)^{2n + 4}}{2n + 1}} ] - 0[/tex]

[tex]\int\limits^{1/2}_{0} x^3 \arctan(x)\ dx = \sum\limits^{\infty}_{n = 0} {(-1)^n \cdot \frac{(1/2)^{2n + 4}}{2n + 1}}[/tex]

The nth term of the series is then represented as:

[tex]T_n = \frac{(-1)^n}{2^{2n + 5} * (2n + 4)(2n + 1)}[/tex]

Solve the series by setting n = 0, 1, 2, 3 ..........

[tex]T_0 = \frac{(-1)^0}{2^{2(0) + 5} * (2(0) + 4)(2(0) + 1)} = \frac{1}{2^5 * 4 * 1} = 0.00625[/tex]

[tex]T_1 = \frac{(-1)^1}{2^{2(1) + 5} * (2(1) + 4)(2(1) + 1)} = \frac{-1}{2^7 * 6 * 3} = -0.0003720238[/tex]

[tex]T_2 = \frac{(-1)^2}{2^{2(2) + 5} * (2(2) + 4)(2(2) + 1)} = \frac{1}{2^9 * 8 * 5} = 0.00004340277[/tex]

[tex]T_3 = \frac{(-1)^3}{2^{2(3) + 5} * (2(3) + 4)(2(3) + 1)} = \frac{-1}{2^{11} * 10 * 7} = -0.00000634131[/tex]

..............

At n = 2, we can see that the value of the series has 4 zeros before the first non-zero digit

This means that we add the terms before n = 2

This means that the value of [tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx[/tex] to 4 decimal points is

[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx = 0.00625 - 0.0003720238[/tex]

Evaluate the difference

[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx = 0.0058779762[/tex]

Approximate to four decimal places

[tex]\int\limits^{1/2}_0 {x^3 \arctan(x)} \, dx = 0.0059[/tex]

Hence, the approximated value of the definite integral is 0.0059

We are given the matrix vector;

[1  3 5 0]

[0 1 4 -2]

Now, let's find the general Ax = 0 solution for the free variables. Thus;

[A, 0] =  

[1 3 5  0]

[0 1 4 -2]

Thus;

R₁ → R₁ - 3R₂

⇒ [1 0 -7  6 0]

   [0 1 4  -2 0]

The general solution is:

x₁ = 7x₃ - 6x₄

x₂ = -4x₃ + 2x₄

x₃ and x₄ are free variables

x = [tex]\left[\begin{array}{ccc}x_{1} &&&x_{2} \\x_{3} \\x_{4} \end{array}\right][/tex] = [tex]x_{3} \left[\begin{array}{ccc}{7} &&&{-4} \\{1} \\{0} \end{array}\right] + x_{4} \left[\begin{array}{ccc}{-6} &&&{2} \\{0} \\{1} \end{array}\right][/tex]

Antigone speaks the words in the given passage to her sister Ismenia. Now, in these words, Antigone questions Ismenia's loyalty and commitment to the family by the use of the word "base" to mean family loyalty.

The reason for use of that word is because their brother was banned from receiving a decent funeral, which prevented his soul from being able to rest in peace. The king then ordered that whoever made a feneral for the brother of Ismenia and Antigona would be condemned to death.

Answer:

Strong Gravitational Field

Explanation:

The slope of the line tangent to the polar curve r = 3θ at the point where θ = π/2 is; Undefined

By converting into parametric equations, we have;

x(θ) = r(θ) cos θ = cos 3θ cos θ

y(θ) = r(θ) sin θ = cos 3θ sin θ

By product rule;

x'(θ) = -sin 3θ cos θ - cos 3θ sin θ

x'(π/2) = -sin 3(π/2) cos (π/2) - cos 3(π/2) sin (π/2)

x'(π/2) = 0

y'(θ) = -sin 3θ sin θ + cos 3θ cos θ

y'(π/2) = -sin 3(π/2) sin (π/2) + cos 3(π/2) cos (π/2)

y'(π/2) = 1

The slope m of the curve is gotten from;

m = y'(π/2)/x'(π/2)

m = 1/0

Thus the slope is undefined
