When x = -1, y = (-1)²-(-1)-2

= 1+1-2

= 0

When x = 0, y = 0²-0-2

= -2

When x = 1, y = 1²-1-2

= -2

When x = 2, y = 2²-2-2

= 0

When x = 3, y = 3²-3-2

= 4

The area of the rectangle as a product of length and width is (6x² + 13x + 6) square units

An equation is an expression that shows the relationship between numbers and variables.

The area of a rectangle is the product of its length and its width. It is given by:

Area = length * width

From the diagram:

Area = 6(x²) + 13(x) + 6(1) = 6x² + 13x + 6 square unit

Also:

Length = x + x + x + 1 + 1 = 3x + 2

Length = 3x + 2 units

Width = x + x + 1 + 1 + 1 = 2x + 3

Width = 2x + 3 units

Area = length * width

Substituting:

Area = (3x + 2)(2x + 3)

Area = 6x² + 9x + 4x + 6 = 6x² + 13x + 6 square units

The area is (6x² + 13x + 6) square units

Answer:

Step-by-step explanation:

step one:

This problem is focused on ratios and fractions

from the problem statement, Martin has 5/6 pizza

Liam has 4 times more of what Martin have

step two:

so we can express what Liam has as

=(5/6)*4 = 20/6or

=5/6+5/6+5/6+5/6= 20/6

= 20/6

step three:

we can reduce both numerator and denominator

= 10/3

Hence Liam has 10/3 pizza

Quantity of pizza that Liam has is;

3 full pizzas and a third of a pizza.

Martin has 5/6 of a pizza.

Thus;

Quantity of pizza that Martin has = 5/6

Now we are told that Liam has 4 times as much as Liam, then;

Quantity of pizza Liam has = 4(5/6) = 10/3

This translates to 3⅓ pizza

Both Walter and Gordon's models of share valuation consider the relationship between dividend policies and the market value of a firm. However, Walter's model focuses solely on the dividend payout ratio, while Gordon's model incorporates the firm's cost of equity and expected growth rate of dividends.

The similarities between Walter and Gordon's models of share valuation are that they both consider dividend policies and their impact on the market value of a firm. Both models assume that the market value of a firm is determined by the dividends paid out to shareholders.

However, there are also differences between the two models. Walter's model suggests that the market value of a firm is directly related to its dividend payout ratio. The higher the payout ratio, the higher the market value. This implies that investors value current dividends more than future growth prospects.

On the other hand, Gordon's model takes into account the firm's cost of equity and its expected growth rate. It suggests that the market value of a firm is determined by the dividend yield (dividends per share divided by the share price) and the expected growth rate of dividends. According to Gordon's model, if the firm's expected growth rate increases, the market value will also increase, even if the dividend payout ratio remains the same.

To illustrate the differences between the two models, let's consider a numerical example. Suppose a firm has earnings per share (EPS) of $5, a cost of equity of 10%, and a required rate of return of 12%. The firm pays out 50% of its earnings as dividends and has an expected growth rate of 5%.

According to Walter's model, the market value of the firm would be calculated as:
Market Value = EPS / Required Rate of Return
Market Value = $5 / 0.12
Market Value = $41.67

According to Gordon's model, the market value of the firm would be calculated as:
Market Value = Dividends per Share / (Required Rate of Return - Expected Growth Rate)
Dividends per Share = EPS * Payout Ratio
Dividends per Share = $5 * 0.5 = $2.5
Market Value = $2.5 / (0.12 - 0.05)
Market Value = $35.71

As we can see, the two models yield different market values for the firm. Walter's model values the firm at $41.67, while Gordon's model values it at $35.71. This difference arises because Gordon's model takes into account the expected growth rate of dividends, whereas Walter's model only considers the dividend payout ratio.

In summary, both Walter and Gordon's models of share valuation consider the relationship between dividend policies and the market value of a firm. However, Walter's model focuses solely on the dividend payout ratio, while Gordon's model incorporates the firm's cost of equity and expected growth rate of dividends.

Answer:

math is basically how to understand  

Step-by-step explanation:

Answer:

Math is a way to view numbers in a more unique and special way. Many people might not like it because they consider it difficult.

Step-by-step explanation:

a)

i) The original cube has a side length of 4 cm. The volume of a cube is calculated by cubing the length of one side. So, the volume of the original cube is 4 cm x 4 cm x 4 cm = 64 cm³.

ii) The enlarged cube has a ratio of 3:1 compared to the original cube. This means that each side length of the enlarged cube is three times the length of the original cube. Therefore, the side length of the enlarged cube is 4 cm x 3 = 12 cm. The volume of the enlarged cube is calculated by cubing the length of one side: 12 cm x 12 cm x 12 cm = 1,728 cm³.

b) To find the ratio by which the volume has been increased, we can compare the volumes of the enlarged and original cubes. The ratio of the enlarged cube's volume to the original cube's volume is 1,728 cm³ : 64 cm³, which simplifies to 27 : 1.

This means that the volume of the enlarged cube is 27 times greater than the volume of the original cube. Therefore, the volume has been increased by a ratio of 27:1.

The given series is convergent. The sum of the series is approximately 6.096. The given series can be written as Σ(1/(7eⁿ)) from n = 1 to infinity. To determine convergence, we can analyze the behavior of the terms as n approaches infinity.

The general term of the series is 1/(7eⁿ), where e is the mathematical constant approximately equal to 2.71828. As n increases, the exponential term eⁿ grows rapidly, causing the denominator to become very large. As a result, each term of the series approaches zero. This suggests that the series is convergent.

To find the sum of the series, we can use the formula for the sum of an infinite geometric series. In this case, the first term (a) is 1/(7e), and the common ratio (r) is 1/e. The sum (S) can be calculated as S = a / (1 - r).

Plugging in the values, we get S = (1/(7e)) / (1 - 1/e). Evaluating this expression gives us the approximate sum of 6.096.

Therefore, the given series is convergent, and its sum is approximately 6.096.

The general form of Bernoulli's differential equation is y' + P(x)y = Q(x)y^n.

Bernoulli's differential equation is a type of nonlinear first-order ordinary differential equation that can be written in the general form:

y' + P(x)y = Q(x)y^n,

where y' represents the derivative of y with respect to x, P(x) and Q(x) are functions of x, and n is a constant. This equation is nonlinear because of the presence of the term y^n, where n is not equal to 0 or 1.

To solve Bernoulli's differential equation, a substitution is made to transform it into a linear differential equation. The substitution is usually y = u^(1-n), where u is a new function of x. Taking the derivative of y with respect to x and substituting it into the original equation allows for the equation to be rearranged in terms of u and x. This substitution converts the original equation into a linear form that can be solved using standard techniques.

After solving the linear equation in terms of u, the solution is then expressed in terms of y by substituting back y = u^(1-n). This gives the final solution to Bernoulli's differential equation.

The factors of g are (x - 10) and (x + 2), which confirms that the zeros are 10 and -2.

The positive integers that can divide a number evenly are referred to as factors.  Let's say we multiply two numbers to produce a result. The product's factors are the number that is multiplied. Each number has a self-referential element.  There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.

The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero (-1). The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.

The zeros are 10 and -2, because the factors of g are (x-10) and (x + 2).

To find the zeros, we can set g(x) equal to zero and solve for x:

x² - 8x - 20 = 0

Using the quadratic formula, we get:

x = [8 ± √(8² + 4(1)(20))] / 2

x = [8 ± √144] / 2

x = [8 ± 12] / 2

So, the zeros are:

x = 10 and x = -2

We can verify this by factoring g(x):

g(x) = x² - 8x - 20

g(x) = (x - 10)(x + 2)

So, the factors of g are (x - 10) and (x + 2), which confirms that the zeros are 10 and -2.

The possible function that satisfies all of those conditions is,

f(x) = -0.5(x-3)(x-1)(x+1) and sketch is attached below.

Given that for a function,

Zeroes at x = 3, x = 1, and x = -1

y-intercept at 3 and have 2 turning points .

considering a function of the form:

f(x) = ax(x-3)(x-1)(x+1)

where a is some constant that we need to determine.

We know that this function is odd because it only contains odd-degree terms.

To find the value of a, we can use the fact that the y-intercept occurs at (0, 3). Plugging in x=0, we obtain,

f(0) = a(0-3)(0-1)(0+1)

     = -3a

     = 3

Solving for a, we find that a=  -1.

Now we have the function,

f(x) = -x(x-3)(x-1)(x+1)

which is odd and has a y-intercept at (0, 3).

To check that this function has zeroes at x=3, x=1, and x=-1,

we can use the zero product property.

We know that if the product of any of the factors is zero, then the entire product f(x) will be zero.

So, we simply need to solve for x when f(x)=0,

f(x) = -x(x-3)(x-1)(x+1) = 0

x=0, 1, -1, and 3 are the solutions to the above equation.

Therefore, f(x) has zeroes at x=3, x=1, and x=-1.

Now to find the turning points,

we can take the first derivative of f(x) and find the critical points where the derivative is zero. The first derivative of f(x) is,

⇒ f'(x) = -4x³ + 6x² + 2x

Setting f'(x) equal to zero and solving for x, we find that the critical points occur at x=-2 and x=2.

Therefore, f(x) has two turning points.

Putting everything together, we get the function,

⇒ f(x) = -0.5(x-3)(x-1)(x+1)

which is odd and has a positive leading coefficient,

After plotting this function we get the required sketch.

The social learning theory suggests that youth who socialize with friends who are highly delinquent will be more apt to be delinquent themselves.

The social learning theory, proposed by Albert Bandura, emphasizes the role of social interactions and observational learning in shaping behavior. According to this theory, individuals learn behaviors through the process of observing others and imitating their actions. In the context of delinquency, the theory suggests that youth who associate with friends who engage in delinquent behaviors are more likely to learn and adopt those behaviors themselves.

This is because they are exposed to models who engage in delinquency and may receive reinforcement or rewards for such behaviors. Through socialization and peer influence, youth internalize the behaviors and attitudes of their delinquent peers, leading to an increased likelihood of engaging in delinquent activities themselves.
