The region that a polygon's boundary encloses is referred to as the polygon's area. In other words, we say that the area that any polygon occupies determines its size.

The measurement of the area that a polygon encloses serves as its definition. The area of a polygon is the space that it takes up in a two-dimensional plane since polygons are closed plane shapes. Every polygon has an area that is measured in square units.

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

Area of rectangle = length × width

Area of parallelogram = base × height

Area of trapezium = (1/2) × (sum of lengths of its parallel sides or bases) × height

Step-by-step explanation:I am sorry if this doesn't help but I dont know the answer???

a) The angle between vectors A and B is approximately 154.68 degrees.To find the angles between the vectors A and B,

we can use the dot product formula and the fact that the dot product of two vectors A and B is given by:

A · B = |A| |B| cos(θ)

where |A| and |B| represent the magnitudes of vectors A and B, respectively, and θ is the angle between them.

Let's calculate the angles for each case:

(a) A = 2î − 7ĵ, B = -5î + 3ĵ:

Using the dot product formula:

A · B = (2)(-5) + (-7)(3) = -10 - 21 = -31

The magnitude of A:

|A| = √(2^2 + (-7)^2) = √(4 + 49) = √53

The magnitude of B:

|B| = √((-5)^2 + 3^2) = √(25 + 9) = √34

Now, we can calculate the angle θ using the formula:

-31 = (√53)(√34)cos(θ)

Simplifying:

cos(θ) = -31 / (√53)(√34)

Using inverse cosine (arccos) to find θ:

θ = arccos(-31 / (√53)(√34))

The angle between vectors A and B is approximately θ = 154.68 degrees.

(b) A = 6î + 4ĵ, B = 3î − 3ĵ:

Using the dot product formula:

A · B = (6)(3) + (4)(-3) = 18 - 12 = 6

The magnitude of A:

|A| = √(6^2 + 4^2) = √(36 + 16) = √52 = 2√13

The magnitude of B:

|B| = √(3^2 + (-3)^2) = √(9 + 9) = √18 = 3√2

Now, we can calculate the angle θ using the formula:

6 = (2√13)(3√2)cos(θ)

Simplifying:

cos(θ) = 6 / (2√13)(3√2) = 1 / (√13)(√2)

Using inverse cosine (arccos) to find θ:

θ = arccos(1 / (√13)(√2))

The angle between vectors A and B is approximately θ = 23.38 degrees.

(c) A = 7î + 5ĵ, B = 5î − 7ĵ:

Using the dot product formula:

A · B = (7)(5) + (5)(-7) = 35 - 35 = 0

The magnitude of A:

|A| = √(7^2 + 5^2) = √(49 + 25) = √74

The magnitude of B:

|B| = √(5^2 + (-7)^2) = √(25 + 49) = √74

Now, we can calculate the angle θ using the formula:

0 = (√74)(√74)cos(θ)

Since the dot product is zero, it indicates that the vectors are orthogonal (perpendicular) to each other. In this case, the angle between vectors A and B is θ = 90 degrees.

Therefore, for the given cases:

(a) The angle between vectors A and

B is approximately 154.68 degrees.

(b) The angle between vectors A and B is approximately 23.38 degrees.

(c) The angle between vectors A and B is 90 degrees.

Answer:

  left-to-right

Step-by-step explanation:

[There's a lot to read here. If you read it, maybe you'll have a better understanding.]

This is asking you the first step required to solve each of the equations.

The general process of solving an equation involves performing operations that result in the variable of interest being on one side of the equal sign (by itself), and everything else being on the other side. When variable and constant terms are mixed, we generally want to remove the variable term.

The underlying rule for all of this is "whatever is done to one side of the equation must also be done to the other side." The exceptions are simplification and substitution.

"Inverse" operations are of use in this process. That is why you are taught about the "additive inverse" (negative) of a number, and the "multiplicative inverse" (reciprocal) of a number. Adding the additive inverse results in the additive identity element (0). Similarly, multiplying by the multiplicative inverse results in the multiplicative identity element (1). Adding 0 or multiplying by 1 leaves only the original value.

__

With this in mind, we can look at the given equations to see what is needed to solve them.

2 +2y = y

  We see that the left side of the equation has both a constant term and a variable term. To remove the variable term we add its additive inverse: (-2y). Adding a negative value is the same as subtracting a positive value. That is, we can describe what we want to do as "subtract 2y from both sides".

When we do that, the result is ...

  2 +2y -2y = y -2y . . . . . here, we show the subtraction

  2 = -y . . . . . . . . . . . . . and this is the result of simplifying that.

Notice the y term is now on one side of the equal sign and the constant is on the other side. We are one step closer to the solution, which is the whole point.

__

5(y -4) = 2y

  This equation has parentheses. It often works well as a first step to eliminate the parentheses, generally using the distributive property. That is, we "distribute 5".

When we do that, the result is ...

  5(y) -5(4) = 2y . . . . . . . . here, we show the distribution

  5y -20 = 2y . . . . . . . and this is the result of simplifying that

This puts us one step closer to the solution, which is the whole point.

__

5y = 10 -2y

Here, the unwanted variable term is -2y on the right side of the equation. To remove it, we add 2y to both sides.

When we do that, the result is ...

  5y +2y = 10 -2y +2y . . . . . . . showing the addition of 2y

  7y = 10 . . . . . . . . . . . . . . . simplified

This puts us one step closer to the solution.

__

5 = 25y

This equation has the variable term and the constant term already separated. However, there is a coefficient on the variable term that is not equal to 1. We want to make that coefficient be 1. To do that, we multiply it by its multiplicative inverse: 1/25. That is, we divide both sides by 25.

When we do that, the result is ...

  5/25 = 25y/25 . . . . . . showing division by 25

  1/5 = y . . . . . . . . . simplified (and the fraction reduced)

This gives us the solution. There are no more steps required.

The minimum wage set by the government at $7.50 per hour does not result in a pay cut for unskilled workers, as it is below the equilibrium wage of $8.00 per hour.

The wage rate remains unchanged, and the labor market remains in balance.

The statement is false.

False.

The equilibrium wage in the market for unskilled labor is $8.00 per hour, which means that the market naturally sets the wage rate at this level, based on the forces of supply and demand.

The government then sets a minimum wage at $7.50 per hour.

Since the minimum wage is below the equilibrium wage, it does not directly impact the wage rate for unskilled workers.
The equilibrium wage represents the point at which the supply of labor (the number of workers willing to work at a given wage) equals the demand for labor (the number of workers that employers are willing to hire at a given wage).

In this case, both workers and employers are satisfied with the $8.00 per hour wage, and the labor market is balanced.
The government sets a minimum wage below the equilibrium wage, it essentially sets a wage floor that is not binding. Employers are still willing to pay the equilibrium wage of $8.00 per hour, and workers are still willing to accept this wage.

The wage for unskilled workers remains at $8.00 per hour, and there is no pay cut of 50 cents per hour.

a) To show that the number of odd terms among C(n,0), C(n,1), C(n,2), ..., C(n,n) is a power of 2, we can use the concept of Pascal's Triangle.

In Pascal's Triangle, each entry represents a binomial coefficient. The binomial coefficient C(n, k) represents the number of ways to choose k items from a set of n items.

The first row of Pascal's Triangle is just 1, which represents C(0,0).

The second row is 1, 1, representing C(1,0) and C(1,1).

The third row is 1, 2, 1, representing C(2,0), C(2,1), and C(2,2).

If we continue this pattern, we can observe that each row of Pascal's Triangle starts and ends with 1, and the numbers in between are the sum of the two numbers directly above them.

Now, let's consider the number of odd terms in each row. The first row has 1 odd term (1).

The second row has 2 odd terms (1 and 1).

The third row has 2 odd terms (1 and 1).

We can notice that in each row, the number of odd terms is always equal to the number of terms in the row.

Therefore, the number of odd terms among C(n,0), C(n,1), C(n,2), ..., C(n,n) is always a power of 2, where the exponent represents the row number of Pascal's Triangle.

b) To determine the number of odd binomial coefficients in the expansion of (x+y)^1000, we can use the Binomial Theorem.

The Binomial Theorem states that the expansion of (x+y)^n can be written as:

(x+y)^n = C(n,0)x^n + C(n,1)x^(n-1)y + C(n,2)x^(n-2)y^2 + ... + C(n,n)y^n

In the expansion, the exponents of x and y range from n to 0, with a decreasing power of x and an increasing power of y.

To find the number of odd binomial coefficients, we need to consider the terms where the corresponding binomial coefficient C(n,k) is odd.

For a binomial coefficient C(n,k) to be odd, the number of 1s in the binary representation of k must be equal to or greater than the number of 1s in the binary representation of n.

Since the exponent of x decreases by 1 in each term and the exponent of y increases by 1, the number of 1s in the binary representation of k determines the power of x in each term.

In the expansion of (x+y)^1000, the number of terms with odd binomial coefficients will be equal to the number of binary numbers with an equal or greater number of 1s than the number of 1s in the binary representation of 1000.

To determine this count, we can convert 1000 to its binary representation:

1000 (base 10) = 1111101000 (base 2)

In the binary representation of 1000, there are 6 1s.

Therefore, the expansion of (x+y)^1000 will have 2^6 = 64 odd binomial coefficients.

The c is equal to half of the definite integral of the function over the interval [0, 2].

To determine c such that f(c) is the average value of the function on the interval [0, 2], we can use the formula for the average value of a function:

avg = 1/(b-a) * ∫(a to b) f(x) dx

In this case, a = 0 and b = 2, so the formula becomes:

avg = 1/2 * ∫(0 to 2) f(x) dx

We want to find the value of c such that f(c) = avg, so we can set these two expressions equal to each other and solve for c:

f(c) = avg
f(c) = 1/2 * ∫(0 to 2) f(x) dx

We can then use calculus to solve for c by finding the derivative of both sides with respect to c and setting them equal to each other:

f'(c) = 1/2 * (f(2) - f(0))

Solving for c gives us:

The value of ƒ(2) for the given piecewise function is -12. This means that when x is exactly 2 or falls within the second condition x ≥ 2, the expression -8x + 4 is used to calculate the value.

Answer :   ƒ(2) = -12.

To evaluate ƒ(2) for the given piecewise function, we need to substitute x = 2 into the appropriate expression based on the given conditions.

For x < 2, the expression is x = 6x + 1. However, since x = 2 in this case, which is not less than 2, we cannot use this expression.

For x >= 2, the expression is -8x + 4. Since x = 2 in this case, which satisfies the condition, we can evaluate ƒ(2) using this expression.

ƒ(2) = -8(2) + 4

      = -16 + 4

      = -12

Therefore, ƒ(2) = -12.

Parallelograms need at least one pair of sides to be parallel.

Squares have to have four sides of equal length

Rectangles need to have all interior angles equal to 90 degrees.

Answer:

m∠D = 49°
m∠E = 41°
m∠F = 90°

Step-by-step explanation:

        We know a triangle's angles add up to 180, so we can create an equation and solve for x. We also know the little box represents 90 degrees.

Given:

        90° + 5x° + 14° + 3x° + 20° = 180°

Combine like terms:

        8x° + 124° = 180°

Subtract 124 from both sides of the equation:

        8x° = 56°

Divide both sides of the equation by 8:

        x = 7

        Now, we will plug this value of x back into the angles to solve. Again, the little box represents that Angle F is equal to 90 degrees.

m∠D = 5x° + 14° = 5(7)° + 14° = 49°
m∠E = 3x° + 20° = 3(7)° + 20° = 41°
m∠F = 90°

Using the linear relationship the height of the candle after 17 hours is 22.3 cm.

As it is given that the height of the candle is linear to the amount of time. The linear relationship is the relationship between two variables such that it follows a straight line.

Now, let the time be on the x-axis and the y-axis is the height of the candle. therefore, the slope of the linear relationship can be represented as,

(x₁, y₁) = (7, 23.3)

(x₂, y₂) = (23, 21.7)

Since we know the two points of the linear relationship, therefore, the slope can be written as,

m = (y₂ - y₁)/(x₂ - x₁)

m = (21.7 - 23.3)/(23 - 7)

m = -1.6/16

m = -1/10

Now, the equation of the linear relationship can be written as,

y - y₁ = m( x - x₁)

y - 23.3 = (-1/10)(x - 7)

10y - 233 = -x + 7

x + 10 y = 240          --(1)

We are asked to determine the height of the candle after 17 hours. So, put x = 17 and find y

17 + 10y = 240

10y = 223

y = 22.3

Hence, the height of the candle after 17 hours is 22.3cm.

The correct answer is:

The independent variable is the "X" variable we have some control over. Some other names for the independent variable are predictor, regressor, model effect (in JMP).

In regression analysis, the independent variable is the variable that is manipulated or controlled by the researcher.

It is the variable that is hypothesized to have an effect on the dependent variable. The independent variable is often denoted as "X" and is used to predict or explain changes in the dependent variable.

For example, in a study examining the relationship between study time and exam scores, study time would be the independent variable because the researcher can manipulate or control the amount of time students spend studying.

The dependent variable, in this case, would be the exam scores, which are expected to change as a result of the different levels of study time.

The dependent variable, on the other hand, is the variable that is being studied or observed and is expected to be influenced by the independent variable.

It is often denoted as "Y" and represents the outcome or response variable.

It's important to note that the independent and dependent variables can vary depending on the research context and the specific study being conducted.
