Rock Particles are categorized into 6 types:

The values of A, B, and C that make the two planes parallel are:   A = (5B - C)/2and5B - 3C = |N₁||N₂|/2 and The values of A, B, and C that make the two planes perpendicular are:  A = (5B - C)/2and5B - 3C = 0.

Let's have a look at the planes. They are:

T₁ = 2x - 5y + z - 4 = 0 and T₂ = Ax + By + Cz + 10 = 0

Now we will try to solve the question using the concepts of vector and normal to the plane.

The vector and normal to the plane can be defined as follows:

A plane is a 2-dimensional surface that is defined by three points.

A normal is a vector that is perpendicular to the plane.

A vector is a quantity that has both magnitude and direction. Let's calculate the normal to both planes using the coefficients of x, y, and z in the equation of the planes.

The equation of the normal to a plane is given by:

N = ai + bj + ck where a, b, and c are the coefficients of x, y, and z in the equation of the plane.

Let's first find the normal to T₁.

The coefficients of x, y, and z are 2, -5, and 1, respectively.

Therefore, the normal to T₁ is given by:

N₁ = 2i - 5j + k

Now let's find the normal to T₂. The coefficients of x, y, and z are A, B, and C, respectively. Therefore, the normal to T₂ is given by:

N₂ = Ai + Bj + Ck

Now that we have found the normals to the two planes, we can determine if they are parallel or perpendicular based on the dot product of the two normals.

The dot product of two vectors is given by:

A.B = |A||B|cosθwhere A and B are two vectors, |A| and |B| are their magnitudes, and θ is the angle between them.

If the dot product of the two normals is zero, then the planes are perpendicular. If the dot product of the two normals is not zero, then the planes are parallel. In this case, we need to find the values of A, B, and C that make the two planes parallel or perpendicular.

Now let's find the dot product of the two normals:

N₁.N₂ = 2A - 5B + C

If the two planes are parallel, then their normals are parallel, which means that the dot product of the two normals is equal to the product of their magnitudes.

Therefore:

N₁.N₂ = |N₁||N₂|I

f the two planes are perpendicular, then their normals are perpendicular, which means that the dot product of the two normals is zero.

Therefore:

N₁.N₂ = 0

Now let's find the values of A, B, and C that make the two planes parallel or perpendicular. If the two planes are parallel, then their normals are parallel.

Therefore, the dot product of the two normals is equal to the product of their magnitudes.

Therefore:

2A - 5B + C = |N₁||N₂|I

f the two planes are perpendicular, then their normals are perpendicular.

Therefore, the dot product of the two normals is zero.

Therefore:2A - 5B + C = 0

Now let's solve the two equations for A, B, and C.

2A - 5B + C = |N₁||N₂|2A - 5B + C = 0A = (5B - C)/2

Substituting this value of A into the equation 2A - 5B + C = |N₁||N₂|, we get:

5B - 3C = |N₁||N₂|/2

Therefore, the values of A, B, and C that make the two planes parallel are:

A = (5B - C)/2and5B - 3C = |N₁||N₂|/2

The values of A, B, and C that make the two planes perpendicular are:

A = (5B - C)/2and5B - 3C = 0

Answer:

The inverse of the function is \(g (x)=-5x-4\).

Step-by-step explanation:

The function provided is:

\(f^{-1}(x)=-\frac{1}{5}\ x-\frac{4}{5}\)

Let us assume that:

\(y=f^{-1}(x)\)

Then the equation will be:

\(y=\frac{-x-4}{5}\)

To compute the inverse of the function substitute x as y and y as x.

\(x=\frac{-y-4}{5}\)

Now solve for y as follows:

\(x=\frac{-y-4}{5}\)

\(5x=-y-4\)

\(y=-5x-4\)

Thus, the inverse of the function is \(g (x)=-5x-4\).

Answer:

The answer is "-5x-4"

Step-by-step explanation:

Given:

\(\bold{f^{-1} (x)=(-\frac{1x}{5}-\frac{4}{5})}\)

solve the above equation:

\(\to f^{-1}(x)= \frac{-x-4}{5}\\\\\to f^{-1}(x)= -\frac{x+4}{5}\\\)

Let

\(y= f^{-1} x= -(\frac{x+4}{5})\\\\\)

inverse the above function:

\(\to x= -(\frac{y+4}{5})\\\\\to 5x= -(y+4)\\\\\to 5x= -y-4\\\\\to\boxed {y=-5x-4}\\\\\)

Let's define the variables:

x = number of adults.

y = number of children.

We know that 133 people used the public swimming pool. then we can write:

x + y = 133

We also know that the receipts for admission totaled 270.75, then we can write other equation as:

2.25x + 1.5y = 270.75

Then the system of equations is:

x + y = 133

2.25x + 1.5y = 270.75

In the first equation we can isolate x to get:

y = 133 - x

Now replace that in the other equation to get:

2.25x + 1.5*(133 - x) = 270.75

0.75x + 199.5 = 270.75

0.75x = 270.75 - 199.5

x = 71.25/0.75 = 95

Option a, adjacency matrix. An adjacency matrix is a two-dimensional array that represents a graph's edges, where the rows and columns correspond to the vertices of the graph. If there is an edge between two vertices, the corresponding element in the matrix is set to 1, otherwise it is set to 0. This implementation is useful for dense graphs, where the number of edges is close to the maximum possible number of edges.

An adjacency matrix is a simple and efficient way to represent graphs that have a large number of vertices and edges. It allows for fast lookups of the existence of an edge and is useful for various algorithms that require graph representation. However, it is not suitable for sparse graphs, where the number of edges is much smaller than the maximum possible number of edges. In such cases, an adjacency list would be more appropriate.

The common implementation of a graph that uses a two-dimensional array to represent the graph's edges is called an adjacency matrix.

The total combinations of fruit he can bring is 20 if Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school the answer is 20.

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school

Total number of fruits = 1+1+1+1+1+1

Total number of fruits = 6

n = 6

He wants to bring three pieces of fruit to school,

r = 3

The difference in the values of the two cars when they are each 7 years old is equal to $6,000.

In order to determine the difference in the values of the two cars, we would have to write an equation that models the price of the cars after a length of time, by using the data points shown in the graph above.

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

For Car A, we have:

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (9 - 12)/(4 - 2)

Slope, m = -3/2

Slope, m = -1.5

At point (4, 9), a linear equation for car's value can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

Where:

Substituting the given points into the formula, we have;

y - y₁ = m(x - x₁)

y - 9 = -1.5(x - 4)

y = -1.5x + 15

In 7 seven years, the value of Car A is given by:

y = -1.5x + 15

y = -1.5(7) + 15

y = $4,500

Note: The negative sign indicates that the value of the car is depreciating.

For Car B, we have:

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (10 - 18)/(5 - 1)

Slope, m = -8/4

Slope, m = -2

At point (5, 1), a linear equation for car's value can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

y - 1 = -2(x - 5)

y = -2x + 11

In 7 seven years, the value of Car B is given by:

y = -2x + 11

y = -2(7) + 3.5

y = $10,500

Now, we can determine the difference as follows:

Difference = $10,500 - $4,500

Difference = $6,000.

To determine if the inspector is justified in claiming that all the engine fan blades must be replaced, we can perform a hypothesis test using the sample variance and the given population variance threshold.

The null hypothesis (H0) is that the population variance is less than or equal to 0.18 mm2, and the alternative hypothesis (Ha) is that the population variance is greater than 0.18 mm2.

Using the chi-square distribution and a significance level of 0.01, we can calculate the critical chi-square value that corresponds to the upper tail area of 0.01.

Next, we calculate the chi-square test statistic using the sample variance, the sample size, and the population variance threshold. If the test statistic exceeds the critical chi-square value, we reject the null hypothesis and conclude that the fan blades must be replaced.

To find a 90% confidence interval for the population standard deviation, we can use the chi-square distribution and the degrees of freedom (n-1), where n is the sample size. The confidence interval will be constructed based on the chi-square values corresponding to the lower and upper tails of 0.05 each.

Performing these calculations will provide the necessary information to determine if the inspector is justified in claiming that all the engine fan blades must be replaced and to establish the confidence interval for the population standard deviation.

Type I error is formed when she concludes the town's unemployment rate is not 9% when it actually is, which is an option (a).

Given that:

A large nationwide poll recently showed an unemployment rate of 9% in the US.

The mayor of a local town wonders if this national result holds true for her town, so she plans on taking a sample of her residents to see if the unemployment rate is significantly different than 9% in her town.

Here the null hypothesis is taken as that the unemployment rate is 9%, whereas the alternative hypothesis is that it is not 9%.

Type I error is the error formed when the null hypothesis is rejected, but the hypothesis is actually true.

So, here the conclusion is that the unemployment rate is not 9%, but it actually is 9%.

Converting 1,000 mg to 1 gram would require moving the decimal place zero places to the left.

Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor. The process may also require selection of the correct number of significant digits, and rounding. Different units of conversion are used to measure different parameters. By definition conversion of units means the conversion between different units and measurements of the same quantity done by the process of multiplication or division. In maths, conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons. Units are used for measuring length, measuring weight, measuring capacity, measuring temperature, and measuring speed.

If we want to calculate how many Grams are 1000 Milligrams we have to multiply 1000 by 1 and divide the product by 1000. So for 1000, we have (1000 × 1) ÷ 1000 = 1000 ÷ 1000 = 1 Gram.

So finally 1000 mg = 1 g
