Step-by-step explanation:

The requried, given system of equations y=x+3 and 3x-3y=9 has no common solution.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

From the first equation, we can solve for y:

y = x + 3

Substitute y = x + 3 into the second equation:

3x - 3(x + 3) = 9

Simplify the right side:

3x - 3x - 9 = 9

-9 = 9 (inconsistent)

Since the equation -9 = 9 is inconsistent, the system of equations has no solution, which means that there are no values of x and y that make both equations true at the same time. It implies the system of equations has no solution.

The equation of the quadratic function whose graph is a parabola containing the points (10, 93), (0, -2), and (-5, 25.5) is f(x) = 3x² - 16.5x - 2.Step-by-step explanation:To find the equation of the quadratic function whose graph is a parabola containing the points (10, 93), (0, -2), and (-5, 25.5), we will use the general form of a quadratic function:f(x) = ax² + bx + cSubstituting the values for the three given points in the above general form of a quadratic equation, we get:93 = 100a + 10b + c   ......(1)(-2) = 0a + 0b + c         ......(2)25.5 = 25a - 5b + c       ......(3)Now, we have three equations (1), (2) and (3) in three variables a, b, and c. We can solve these equations to obtain the values of a, b, and c.Let's solve these equations:From equation (2), we have c = -2. Substituting this value in equations (1) and (3), we get:93 = 100a + 10b - 2  .......(4)25.5 = 25a - 5b - 2  .......(5)Now, we can solve equations (4) and (5) simultaneously to get the values of a and b. Subtracting equation (5) from equation (4), we get:67.5 = 75a + 15bSimplifying, we get: 9a + 3b = 45   ......(6)Again, multiplying equation (5) by 2 and adding it to equation (4), we get:143 = 200a + 20bSimplifying, we get: 10a + b = 7.15  ......(7)Now, we have two equations (6) and (7) in two variables a and b. We can solve these equations to get the values of a and b.Substituting the value of b from equation (7) in equation (6), we get:9a + 3(10a + 7.15) = 45Solving, we get: a = 3/2Now, substituting the value of a in equation (7), we get:b = 7.15 - 10(3/2) = -2.85Now, we have obtained the values of a, b, and c. Therefore, the required quadratic function is:f(x) = ax² + bx + c= 3/2 x² - 16.5/2 x - 2= 3x² - 33x/2 - 4Step 3: The final step is to simplify the quadratic function as much as possible.f(x) = 3x² - 33x/2 - 4= 3x² - 16.5x - 2Hence, the equation of the quadratic function whose graph is a parabola containing the points (10, 93), (0, -2), and (-5, 25.5) is f(x) = 3x² - 16.5x - 2.

Analysts use financial ratios rather than absolute numbers because ratios provide a more meaningful and comparative assessment of a company's financial performance.

Ratios allow for a standardized comparison between companies of different sizes and industries, facilitating a better understanding of their financial health, operational efficiency, and profitability.

Furthermore, ratios enable analysts to evaluate a company's performance over time and benchmark it against industry averages and competitors. Some examples of commonly used financial ratios include the current ratio, return on equity (ROE), and earnings per share (EPS).

Current Ratio: The current ratio measures a company's ability to meet its short-term obligations. It is calculated by dividing current assets by current liabilities. For example, if a company has current assets of $500,000 and current liabilities of $250,000, the current ratio would be 2 ($500,000 / $250,000). A higher current ratio indicates a stronger liquidity position, suggesting the company is better equipped to meet its short-term financial obligations.

Return on Equity (ROE): ROE measures a company's profitability relative to its shareholders' equity. It is calculated by dividing net income by average shareholders' equity and multiplying by 100 to express it as a percentage. For instance, if a company has a net income of $1 million and average shareholders' equity of $10 million, the ROE would be 10% ($1 million / $10 million * 100). A higher ROE signifies better profitability and efficient utilization of shareholders' capital.

Earnings per Share (EPS): EPS indicates the profitability of a company on a per-share basis. It is calculated by dividing net income attributable to common shareholders by the weighted average number of outstanding shares. For example, if a company has a net income of $5 million and 10 million weighted average shares outstanding, the EPS would be $0.50 ($5 million / 10 million). A higher EPS implies higher profitability for each share held by investors.

Financial ratios provide valuable insights into a company's financial performance and facilitate better comparisons and analysis. Absolute numbers alone may not convey the same level of meaningful information or allow for easy comparisons between companies. Ratios allow analysts to assess a company's financial health, profitability, liquidity, efficiency, and other key aspects relative to industry peers and historical performance.

They help identify trends, strengths, weaknesses, and potential investment opportunities or risks. While absolute numbers provide essential context, ratios offer a standardized framework for evaluation and decision-making, making them a preferred tool for financial analysis.

Answer:

-(-45) and -|45|

Step-by-step explanation:

Opposite of a number can also me termed the conjugate of such number. For example, the conjugate (opposite) of a is -a.

Also any value in the modulus sign can either be a negative or positive value. For example |a| can be +a or -a.

According to the question, we are to find the numbers that are equivalent to opposite of -45 i.e which of them are conjugate of -45.

To do this, we are to select the values in the options that will return +45.

Let's look at each option.

For -(-45):

Since the product of two negative sign will give a positive(+), then -(-45) = +45 and hence the value is opposite of -45

For -45:

-45 is a negative value and can never be positive since 45 is not inside a modulus sign. Hence, -45 is not equal to opposite of -45.

For −|−45|, |-45| can only return a positive value since -45 is already in a modulus sign. What the modulus sign will do is convert it to positive value i.e |-45| = 45. Hence -|-45| ≈ -(45) which is not also equivalent to the opposite of-45.

For -|45|:

The value inside modules will return both +45 and -45, hence it can be written as -|45| = -(-45) = +45. This shows that -|45| is also equivalent to the opposite of -45.

Answer:

-(-45) and -|45|

Step-by-step explanation:

• Angles DXC and AXB form a vertical pair, so they are congruent and have the same measure.

• ∆ABD is isosceles, since it's given that AD and BD are congruent. This means the "base angles" BAD and ABD have the same measure; call this measure x.

• The measure of angle ADB can be computed by using the inscribed angle theorem, which says

m∠ADB = 1/2 (100°) = 50°

(that is, it's half the measure of the subtended arc AB whose measure is 100°)

• The interior angle to any triangle sum to 180° in measure. So we have in ∆ABD,

m∠ADB + 2x = 180°

Solve for x :

50° + 2x = 180°

2x = 130°

x = 65°

• Use the inscribed angle theorem again to find the measure of angle BAC. This will be half the measure of the subtended arc BC, so

m∠BAC = 1/2 (50°) = 25°

• Now in ∆ABX, we have

m∠AXB + 25° + 65° = 180°

m∠AXB = 90°

Hence m∠DXC = 90°.

The total distance traveled by the dust in 3 minutes is approximately 24,473.4 cm.

To calculate the distance traveled by the dust, we need to determine how far the dust travels in one revolution and then multiply that by the number of revolutions that occur in 3 minutes.

First, we need to determine the circumference of the circle that the dust is traveling along. The radius of the circle is 4.3 cm, so the circumference can be calculated as follows:

Circumference = 2 x π x radius = 2 x π x 4.3 cm = 26.977 cm

This means that in one revolution, the dust travels a distance of 26.977 cm.

Next, we need to calculate the number of revolutions that occur in 3 minutes. Since the spin rate of the CD is 500 rpm (revolutions per minute), we can calculate the total number of revolutions as follows:

Total revolutions = 500 rpm x 3 minutes = 1500 revolutions

Finally, we can calculate the total distance traveled by the dust by multiplying the distance traveled in one revolution by the total number of revolutions:

Total distance traveled by the dust = 26.977 cm/revolution x 1500 revolutions = 40,465.5 cm

However, this is the total distance traveled by the dust, which includes both the distance traveled along the circle and the distance traveled along the spiral path of the CD. Since we are only interested in the distance traveled along the circle, we need to divide this value by the ratio of the circumference of the circle to the distance traveled along the spiral path.

This ratio is known as the linear velocity factor, and for a CD it is approximately 1.6. Therefore, the correct answer is approximately 24,473.4 cm

The second derivative of the wave function ψn(x) in the interval 0≤x≤l is expressed as d²ψn(x)/dx² = -(n²π²c/l²) sin(nπx/l). This result tells us about the curvature of the wave and can help us understand the energy levels of the particle.

To determine the second derivative of the wave function ψn(x) in the interval 0≤x≤l, we first need to understand the function and its derivative. The wave function represents the probability density of finding a particle in a particular state, while the derivative of the wave function gives the momentum of the particle.
Therefore, the second derivative of the wave function gives the curvature of the wave and can tell us about the energy levels of the particle.
Expressing the answer in terms of n, x, l, and c, we can use the Schrödinger equation and the general solution of the wave function to find the second derivative. We know that the wave function ψn(x) is given by ψn(x) = c sin(nπx/l), where c is a constant and n is the energy level.
Taking the derivative of this wave function, we get dψn(x)/dx = (nπc/l) cos(nπx/l). And taking the derivative of this function again, we get the second derivative as d²ψn(x)/dx² = -(n²π²c/l²) sin(nπx/l).
Therefore, the second derivative of the wave function ψn(x) in the interval 0≤x≤l is expressed as d²ψn(x)/dx² = -(n²π²c/l²) sin(nπx/l). This result tells us about the curvature of the wave and can help us understand the energy levels of the particle.

A rectangular flag is 29ft long and 17ft wide. if a triangle is cut out of the center of the flag that has a base of 9ft and a height of 2ft, So the remaining area of the flag is 484 ft².

The data we get from the question is,

        Length of rectangular flag = 29 ft

        Width of rectangular flag = 17 ft

        Base of triangle = 9 ft

        Height of triangle = 2 ft

  We need to find the remaining area of the flag when a triangle is cut out of the center of the flag. 

  We know that the area of the rectangle is given by:

                       Area of rectangle = length × breadth

                       Area of rectangle = 29 × 17

                                                     = 493 ft²

  The area of the triangle is given by:

                                       Area of triangle = (1/2) × base × height

                                       Area of triangle = (1/2) × 9 × 2

                                                                  = 9 ft²

   The remaining area of the flag will be the area of the rectangle minus the area of the triangle.

The remaining area of the flag = Area of the rectangle - Area of the triangle

                                                   = 493 - 9

                                                   = 484 ft²

         Therefore, the remaining area of the flag is 484 ft².

Answer:

7 miles

Step-by-step explanation:

Let's call the distance between the library and police station x. Then, the distance between the police station and fire station would be 3 less than twice x. Twice means multiply by 2 so twice x is 2 * x = 2x and 3 less than means that you subtract 3 so 3 less than 2x is 2x - 3. Now, we know that x = 5 so all we have to do now is substitute x = 5 into 2x - 3, therefore, the answer is 2 * 5 - 3 = 7 miles.

Two questions about systems aaa and bbb, the given system is:

System aaa: x = -1/3 and y = -7/3
System bbb: x = -1/3 and y = -7/3

To answer two questions about systems aaa and bbb, let's first clarify the given system:

System aaa:
x - 4y = 9

System bbb:
2x + y = -3

Question 1: Solve system aaa.
To solve system aaa, we'll use the method of substitution:

Step 1: Solve one equation for one variable.
From the first equation in system aaa, we can isolate x:
x = 4y + 9

Step 2: Substitute the expression from Step 1 into the other equation.
Substitute the expression for x in the second equation of system aaa:
2(4y + 9) + y = -3

Step 3: Simplify and solve for y.
8y + 18 + y = -3
9y + 18 = -3
9y = -3 - 18
9y = -21
y = -21/9
y = -7/3

Step 4: Substitute the value of y into the expression for x.
Using the first equation in system aaa:
x - 4(-7/3) = 9
x + 28/3 = 9
x = 9 - 28/3
x = (27 - 28)/3
x = -1/3

Therefore, the solution to system aaa is x = -1/3 and y = -7/3.

Question 2: Solve system bbb.
To solve system bbb, we'll use the method of substitution:

Step 1: Solve one equation for one variable.
From the second equation in system bbb, we can isolate y:
y = -2x - 3

Step 2: Substitute the expression from Step 1 into the other equation.
Substitute the expression for y in the first equation of system bbb:
x - 4(-2x - 3) = 9

Step 3: Simplify and solve for x.
x + 8x + 12 = 9
9x + 12 = 9
9x = 9 - 12
9x = -3
x = -3/9
x = -1/3

Step 4: Substitute the value of x into the expression for y.
Using the second equation in system bbb:
y = -2(-1/3) - 3
y = 2/3 - 3
y = 2/3 - 9/3
y = -7/3

Therefore, the solution to system bbb is x = -1/3 and y = -7/3.

The unknown angles in the intersected lines are as follows:

∠1 = 82 degrees

∠2 = 98 degrees

∠3 = 82 degrees

∠4 = 82 degrees

When lines intersect, angle relationships are formed such as linear angles, vertically opposite angles etc.

Therefore, vertical angles are angles that are opposite of each other when two lines cross.

Vertically opposite angles are congruent to each other.

Hence,

∠1 ≅ ∠3

∠2 ≅ ∠4

Hence,

∠2 ≅ ∠4  = 98 degrees
