Answer:

-4/5

Step-by-step explanation:

Because a perpendicular slope is the the opposite of the original slope.

Answer:

m=-4/5

Step-by-step explanation:

A line perpendicular simply has the negative reciprocal of the slope of the line they gave you. This means you flip it, and multiply by -1 conceptually.  

Answer:

Width = 5 meters

Length = 12 meters

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Perimeter = 34 meters

Width = x meters

Length = 2x + 2 meters

Perimeter of a rectangle = 2(length + width)

34 = 2{(2x+2) + x}

34 = 2(2x + 2 + x)

34 = 2(3x + 2)

34 = 6x + 4

34 - 4 = 6x

30 = 6x

x = 30 / 6

x = 5 meters

Width = x meters = 5 meters

Length = 2x + 2 meters

= 2(5) + 2

= 10 + 2

= 12 meters

Step-by-step explanation:

Exponential function is

\(y = a \times {b}^{x} \)

where a is the y intercept, or the initial value.

b is the constant rate.

Since a is the y intercept, this means a is 8. So we have

\(y = 8 \times {b}^{x} \)

Now, plug in 9 for x. 512 for y to find b.

\(512 = 8 \times {b}^{9} \)

\(64 = {b}^{9} \)

\( \sqrt[9]{64} = b\)

\(64 {}^{ \frac{1}{9} } = b\)

\(4 {}^{ \frac{1}{3} } = b\)

\( \sqrt[3]{4} = b\)

So the equation is

\(y = 8( \sqrt[3]{4} ) {}^{x} \)

Answer:

Y= 4   and    X=2

Step-by-step explanation:

When you are trying to find the X or Y value for an equation, set the opposite value to zero. That means that if you are trying to find Y in 6x+3y=12, you would make the X zero. Since six is being multiplied by X and X now equals zero, your equation for finding the Y value is now 3y=12. Divide them both by three and you get Y=4. In order to find your X value you would do the same thing. Since you are trying to find X, set the Y value to zero. That makes your equation for finding the X value 6x=12. That is because, again, you set Y to zero, and three times zero is zero. 6x=12 equals X=2 because you divide both sides by 6.

If a matrix is diagonalizable then it is invertible is False.

A matrix can be diagonalizable but not invertible. For example, the zero matrix (a matrix where all entries are 0) is diagonalizable but not invertible.

What is diagonalizable metrix?

A diagonalizable matrix is a square matrix that can be transformed into a diagonal matrix through a similarity transformation. In other words, a matrix A is diagonalizable if there exists an invertible matrix P and a diagonal matrix D such that A = PDP⁻¹.

Geometrically, diagonalizable matrices represent linear transformations that stretch or shrink the space along a set of independent directions, which are called eigenvectors. The diagonal entries of the diagonal matrix D correspond to the eigenvalues of A, which represent the scaling factors along these directions.

Not all matrices are diagonalizable. A matrix is diagonalizable if and only if it has a sufficient number of linearly independent eigenvectors. In particular, symmetric matrices are always diagonalizable, and non-diagonalizable matrices are often associated with non-invertible linear transformations or defective geometric structures.

A large pizza could be $10 and a medium pizza could be $7.

A solution is a specific kind of homogeneous mixture made up of two or more substances that is used in chemistry. A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture. Chemical polarity effects are involved in the mixing of a solution at a scale that leads to interactions that are unique to solvation. When the solvent makes up a larger portion of the mixture, as is frequently the case, the solution typically has the state of the solvent. The concentration of a solution, which measures how much solute is present in a specific volume of solution or solvent, is one crucial parameter. When water is one of the solvents, the phrase "aqueous solution" is used.

Let x = large pizza, y = med pizza

y = x - 3

2x = 2y + 6

2x = 2(x - 3) + 6

2x = 2x - 6 + 6

0 = 0

There are an infinite number of solutions.

The answer is , the area of this triangle is 14 unit².

To find the area of this non-right triangle with sides 4 and 7 and a 30-degree angle between them, we can use the formula for the area of a triangle given two sides and the included angle:
Area = (1/2) * side1 * side2 * sin(angle)
Plugging in the given values:
Area = (1/2) * 4 * 7 * sin(30)
Since sin(30) = 0.5, the equation simplifies to:
Area = (1/2) * 4 * 7 * 0.5
Area = 2 * 7
Area = 14 unit²

The volume of the solid is approximately 16.94 cubic units.

The intersection point of the two curves is (2, 6).

To find the height and radius of each cylindrical shell. Let's take a small vertical strip of width dx at a distance x from the y-axis. The height of this strip is the difference between the two curves:

h(x) = 3x - 3x^2

The radius of the shell is simply x, since it is the distance from the y-axis to the edge of the region.

The volume of each cylindrical shell is given by:

dV = 2πrh dx

Substituting for h and r, we get:

dV = 2πx(3x - 3x^2) dx

Integrating from x = 0 to x = 2, we get:

V = ∫(0 to 2) 2πx(3x - 3x^2) dx

Simplifying and integrating, we get:

V = π[2^4 - 2(2^5/5) + 2^6/9]

Therefore, the volume of the solid is approximately 16.94 cubic units.

According to the brief report by NCHS, approximately 6% of women in the United States married for the first time before their 18th birthday, and 50% of women married by their 25th birthday. 74% of women married by their 30th birthday.The probability of a family with two daughters marrying at different ages is asked in the question. The probability that both daughters will be married by the ages of 18, 25, and 30 will be determined

The question requires finding the probability that both daughters of a family will be married by the ages of 18, 25, and 30 respectively. Since each daughter's wedding is a separate event, the individual probability of a daughter marrying at a given age will be determined separately and then multiplied together to get the probability of both daughters being married at the given age. So, let's find the probabilities of each daughter marrying at a given age:

Probability of one daughter getting married by 18 years:

As per the brief report, 6% of women in the United States married before the age of 18.

Therefore, the probability of one daughter getting married before the age of 18 is 0.06

Probability of one daughter getting married by 25 years:

As per the brief report, 50% of women in the United States get married by the age of 25. Therefore, the probability of one daughter getting married by 25 years is 0.5.

Probability of one daughter getting married by 30 years:

As per the brief report, 74% of women in the United States get married by the age of 30. Therefore, the probability of one daughter getting married by 30 years is 0.74.

The probability of both daughters getting married at the same age is the product of each daughter's probability of getting married at that age.

The probability that both daughters will get married before the age of 18 is:

P(both daughters married at 18 years) = P(daughter1 married at 18) × P(daughter2 married at 18)= 0.06 × 0.06= 0.0036

The probability that both daughters will get married by the age of 25 is:

P(both daughters married at 25 years) = P(daughter1 married at 25) × P(daughter2 married at 25)= 0.5 × 0.5= 0.25

The probability that both daughters will get married by the age of 30 is:

P(both daughters married at 30 years) = P(daughter1 married at 30) × P(daughter2 married at 30)= 0.74 × 0.74= 0.5476

The probability that in a family with two daughters, both will be married before the age of 18 is 0.0036. The probability that both daughters will be married by the age of 25 is 0.25. Finally, the probability that both daughters will be married by the age of 30 is 0.5476.

An unnormalized relation refers to a table in a relational database that contains more than one row. This means that there are duplicate rows in the table, which violates the rules of normalization.

Normalization is a process in database design that aims to eliminate data redundancy and ensure data integrity. It involves breaking down a database into multiple tables and defining relationships between them. By doing so, we can efficiently store and retrieve data while minimizing inconsistencies.

In an unnormalized relation, duplicate rows can lead to various problems. For example, it can result in data inconsistencies, as updating one instance of a row may not reflect changes in other duplicate rows. Additionally, it can cause unnecessary storage and maintenance overhead.

To normalize an unnormalized relation, we need to identify the functional dependencies in the table and create separate tables for related data. This helps organize the data and reduces redundancy.

In summary, an unnormalized relation is a table in a relational database that has duplicate rows. It is important to normalize such relations to ensure data integrity and efficiency.

Answer:

x = ± 3

Step-by-step explanation:

given y varies as \(\frac{1}{x^2}\) , then

y = k × \(\frac{1}{x^2}\) = \(\frac{k}{x^2}\) ← k is the constant of variation

to find k use the condition x = 2 , y = 1

1 = \(\frac{k}{2^2}\) = \(\frac{k}{4}\) ( multiply both sides by 4 )

4 = k

y = \(\frac{4}{x^2}\) ← equation of variation

when y = \(\frac{4}{9}\) , then

\(\frac{4}{9}\) = \(\frac{4}{x^2}\) ( cross- multiply )

4x² = 36 ( divide both sides by 4 )

x² = 9 ( take square root of both sides )

x = ± \(\sqrt{9}\) = ± 3
