Answer:

\( \boxed{ \tt{d = \sqrt{D^{2} -\frac{4A}{\pi}} }}\)

Step-by-step explanation:

\(if \: A=\frac{\pi *D^{2} }{4} - \frac{\pi *d^{2} }{4} \\ then \to \\ A = \frac{\pi}{4} (D^{2} - {d}^{2} ) \\ (D^{2} - {d}^{2} ) \pi = 4A \\ D^{2} - {d}^{2} = \frac{4A}{\pi} \\ {d}^{2} = D^{2} -\frac{4A}{\pi} \\ d = \sqrt{D^{2} -\frac{4A}{\pi}} \)

Answer:

\(\boxed{\text{\Large \sqrt{-1.27324A+D^2}$}}\)

Step-by-step explanation:

\(\displaystyle A=\frac{\pi \times D^2}{4} - \frac{\pi \times d^2}{4}\)

\(\displaystyle A=0.785398D^2 - 0.785398d^2\)

Solve for d

\(\displaystyle A-0.785398D^2= - 0.785398d^2\)

\(\displaystyle \frac{A-0.785398D^2}{- 0.785398} = d^2\)

\(-1.27324A+D^2=d^2\)

\(\displaystyle \sqrt{-1.27324A+D^2} =d\)

Algebra is the branch of mathematics that deals with numbers and values which are represented with letters and symbols.

Sometimes, we do not want to mention a particular number, we can represent the number by a letter or a suitable symbol. This approach is algebraic.

For example, d + d = 2d

This is an example of an algebraic expression

Given the algebraic expression,

\(3\frac{1}{8} \div (x - 4 \frac{7}{28} ) = \frac{17}{18} + 1 \frac{5}{6} \)

Step 1:

Simplify the expression by converting the mixed numbers into improper fractions:

25/8 ÷ ( x - 119/28) = 17/18 + 11/6

Step 2: Simplify the right side of the equation

25/8 ÷( x - 119/28) = 17/18 + 33/18

25/8 ÷( x - 119/28) = 50/18

Step 3: Multiply both sides of the equation by (x - 119/28)

25/8 = 50/18 × (x - 119/28)

Step 4: Multiply both sides of the equation by (18/50)

25/8 × (18/50) = (x - 119/28)

Step 5: Simplify the left side of the equation

9/8 = (x - 119/28)

Step 6: Add 119/28 to both sides of the equation

9/8 + 119/28 = x

Step 7: Calculate the value of x:

x = 9/8 + 119/28

= 63/56 + 238/56

= 301/56

By following these guidelines given below, teens can support the development of a healthy and resilient brain as they transition into adulthood.

A teen's decision-making can have a significant impact on their brain development. During adolescence, the brain undergoes structural and functional changes, particularly in the prefrontal cortex, which is responsible for decision-making, impulse control, and reasoning. The brain's reward center, the limbic system, also plays a prominent role during this period. When teens make choices, especially those related to risk-taking behaviors, it can affect the development and wiring of these brain regions.

To help teens strengthen their brains as they mature into adults, here is some advice:

Engage in balanced and healthy activities: Encourage teens to participate in a range of activities that promote physical, mental, and emotional well-being, such as exercise, reading, hobbies, and creative outlets.

Foster critical thinking skills: Encourage teens to question information, think critically, and consider the consequences of their decisions. Engaging in debates, discussing ethical dilemmas, and seeking multiple perspectives can help develop critical thinking abilities.

Practice self-regulation: Encourage teens to develop self-control and impulse management skills. This can involve techniques like deep breathing, mindfulness, and taking a pause before making impulsive decisions.

Seek positive role models and peer groups: Encourage teens to surround themselves with positive influences and supportive friends who engage in responsible behaviors and make sound decisions.

Prioritize sleep and stress management: Emphasize the importance of adequate sleep and stress reduction techniques, as these factors greatly impact brain health and cognitive function.

By following these guidelines, teens can support the development of a healthy and resilient brain as they transition into adulthood.

The dividends per share for preferred stock for each year are: Year 1 - $1.25, Year 2 - $2.25, Year 3 - $3.25. The dividends per share for common stock for each year are all $0.

To determine the dividends per share for preferred and common stock for each year, we need to divide the total dividends by the number of shares for each type of stock.

Preferred Stock:

Dividends per share of preferred stock = Total dividends for preferred stock / Number of preferred shares

Year 1:

Dividends per share of preferred stock for Year 1 = $50,000 / 40,000 shares = $1.25

Year 2:

Dividends per share of preferred stock for Year 2 = $90,000 / 40,000 shares = $2.25

Year 3:

Dividends per share of preferred stock for Year 3 = $130,000 / 40,000 shares = $3.25

Common Stock:

Dividends per share of common stock = Total dividends for common stock / Number of common shares

Year 1:

Dividends per share of common stock for Year 1 = ($50,000 - Total dividends for preferred stock) / 100,000 shares = ($50,000 - $50,000) / 100,000 shares = $0

Year 2:

Dividends per share of common stock for Year 2 = ($90,000 - Total dividends for preferred stock) / 100,000 shares = ($90,000 - $90,000) / 100,000 shares = $0

Year 3:

Dividends per share of common stock for Year 3 = ($130,000 - Total dividends for preferred stock) / 100,000 shares = ($130,000 - $130,000) / 100,000 shares = $0

The dividends per share for preferred stock for each year are: Year 1 - $1.25, Year 2 - $2.25, Year 3 - $3.25. The dividends per share for common stock for each year are all $0.

Answer:

  (d)  (1, 2)

Step-by-step explanation:

You want to know which of the given points satisfies the inequality.

We find it easiest to plot the given points on a graph of the solution. This shows us that (1, 2) is a solution to the inequality. (It lies in the solution area.)

__

Additional comment

Another way to choose the answer is to try each of the points in the inequality.

If you can visualize the boundary line (without plotting it) as a line with positive slope and a y-intercept of 2, you can more readily reject the first choice and accept the last choice. (0, 3) is above the y-intercept, and (1, 2) is to the right of it (in the solution space).

You may also recognize the x-intercept will be -3, so the second choice lies above the boundary line.

If triangles ΔXYZ is congruent to ΔJKL, then the segment which corresponds to KJ is YX.

Given that, two triangles ΔXYZ and ΔJKL are congruent to each other.

So the corresponding vertices are,

Vertex X of ΔXYZ corresponds to vertex J of ΔJKL

Vertex Y of ΔXYZ corresponds to vertex K of ΔJKL

Vertex Z of ΔXYZ corresponds to vertex L of ΔJKL

Now, the segment which corresponds to KJ in ΔXYZ will be the segment formed by joining the vertices that corresponds to K and J.

We already have,

K corresponds to Y and J corresponds to X.

So the equivalent segment is YX.

Hence the segment required is YX.
