Which of these classes do the matrices A and B belong to more than one answer is possible for each matrix: invertible; orthogonal; projection; permutation; diagonalizable; Markov. A= [001, 010, 100] B [ 111,111,111]
Matrix A belongs to the permutation and Markov classes.
This is the case for matrix A, as it has one 1 in each row and column and 0s everywhere else. Matrix A is also a Markov matrix, which means that all the entries are non-negative and the sum of each row is equal to 1. This can be seen by summing each row, which yields 1+0+0 = 1, 0+1+0 = 1, and 1+0+0 = 1.
Matrix B belongs to the orthogonal, projection, and diagonalizable classes. Matrix B is orthogonal, which means that it is a square matrix whose columns and rows are orthonormal unit vectors (i.e. the dot product of any two columns or rows is 0). This is the case for matrix B, as the dot product of any two columns or rows yields 0. Matrix B is also a projection matrix, which means that it is a square matrix whose columns are all of unit length (i.e. the dot product of any two columns or rows is 1). This can be seen by taking the dot product of any two columns or rows, which yields 1. Finally, matrix B is diagonalizable, which means that it can be transformed into a diagonal matrix using a similarity transformation. This can be seen by calculating the eigenvalues and eigenvectors of matrix B, which yields the same diagonal matrix.

when calculating the percent of pitches thrown at least 92 mph, why did we have to subtract from 100%?
When calculating the percent of pitches thrown at least 92 mph, we subtract from 100% to find the percentage of pitches that fall within a certain threshold (in this case, 92 mph).
When calculating the percentage of pitches thrown at a certain speed, say 92 mph, we use 100% as a reference point. 100% means all of the pitches. By subtracting the percentage of pitches thrown below 92 mph from 100%, we find the percentage of pitches that were thrown at 92 mph or above. This helps us understand what proportion of pitches were thrown at this speed or higher, compared to the total number of pitches thrown. By doing this, we can see how many pitches fall within a certain threshold, in this case 92 mph or above.

a runner starts 125 m west of a flagpole and runs east at 8.0 m/s. how long does it take the runner to reach the flagpole?
It takes the runner distance 15.625 seconds to get to the flagpole because 125m/8m/s equals 15.625s.
1. Determine the distance: 125 metres
2. Determine the velocity: 8 m/s
3. Calculate the time as follows: 125 m/ 8 m/s = 15.625 s
We must know the distance the runner must cover and their pace in order to determine how long it will take them to get to the flagpole. This time, the runner begins 125 metres west of the flagpole and moves east at a speed of 8.0 metres per second. The formula distance (in meters)/speed (in metres per second) = time can be used to determine how long it takes the runner to get to the flagpole (in s). Given that the speed is 8 m/s and the distance is 125 m, the calculation is 125 m/ 8 m/s = 15.625 s. It follows that the runner needs 15.625 seconds to get to the flagpole. This formula can be used to determine how long it will take any object to go a specific distance at a specific speed. It is crucial to remember that in order to obtain the duration in s, the speed must be expressed in m/s and the distance must be expressed in m.

Answer:
1/2
Step-by-step explanation:
So the point of this question is to compare all of the answers and see which one fits best. To do this, first change the denominator to match 5/8. To convert 1/2 into eighths, multiply 2 by 4 so you get eight. Since you did that, you have to do the same to the numerator. Therefore:
1/2 = 4/8
Is 4/8 less than 5/8? Yes. Is it greater than 1/9? Yes, but how? Do the same thing but instead convert 1/2 into ninths. Multiple 2 by 4.5 to get 9 and 1 by 4.5 to get 4.5.
1/2 = 4.5/9
4.5/9 is greater than 1/9, so you answer would be 1/2.
Normally you would test every answer, but to save time I'll just stop there because the first option was correct. I hope you understand. :)
Answer:
1/2
Step-by-step explanation:
1/2 = 4/8 which is less than 5/8.

the fourteen digits of an account number are to be written, one per unit square, in the string of unit squares below. the sum of any three consecutive digits is 15. what is the value of x?
The value of x is 4 which means that the first digit in the sequence is 4, the second digit is 5, the third digit is 6, and so on.
This problem is asking for the value of x in a sequence of 14 digits where the sum of any three consecutive digits is equal to 15. To solve for x, we can use the information provided and basic algebra.
Let's assign a variable to each of the 14 digits in the sequence. For example, let x be the first digit, (x + 1) be the second digit, (x + 2) be the third digit, and so on. Then, the sum of any three consecutive digits must equal 15:
x + (x + 1) + (x + 2) = 15
Expanding and solving for x, we get:
3x + 3 = 15
3x = 12
x = 4
So, the value of x is 4. This means that the first digit in the sequence is 4, the second digit is 5, the third digit is 6, and so on. By continuing this pattern, we can fill in the entire sequence of 14 digits such that the sum of any three consecutive digits is equal to 15.

1. The equation is z^{16} = -1 - i.
We have express our answer in the form of

When we enter it into the first equation, we obtain,
[tex]r^{16}e^{16i\theta }=-1-i\; \; \; \; \; \; \; \; \; \; \; \;[/tex]--(2)
Using the modulus of both sides, we obtain,

Divide by √2 on both side, we get
[tex]e^{16i\theta }=-\frac{1}{\sqrt{2}}-\frac{1}{\sqrt{2}}i[/tex]
We can write [tex]e^{16i\theta }[/tex] as
[tex]\; \; \; \;cos16\theta +isin16\theta =-\frac{1}{\sqrt{2}}-\frac{1}{\sqrt{2}}i[/tex]
On comparing, we get
[tex]\; \; \; \;cos16\theta=-\frac{1}{\sqrt{2}}\;, \; \; \; \; \; \; \; sin16\theta =-\frac{1}{\sqrt{2}}[/tex]
Angle must therefore be in the third quadrant.
[tex]16\theta=\pi +\frac{\pi }{4}=\frac{5\pi }{4}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;16\theta=\frac{5\pi }{4}+2\pi =\frac{13\pi }{4}[/tex]
[tex]\theta=\frac{5\pi }{64}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;\theta=\frac{13\pi }{64}[/tex]
So, second smallest positive argument = 13π/64.
2) The equation is [tex]z^{13} = -1 +\sqrt{3i}[/tex].
We have express our answer in the form of
[tex]\; z = re^{i\theta }[/tex]
When we enter it into the first equation, we obtain,
[tex]r^{13}e^{13i\theta }=-1+\sqrt{3}i\; \; \; \; \; \; \; \; \; \; \; \;[/tex]
Using the modulus of both sides, we obtain,
[tex]\left |r^{13} \right |\: \: \left | e^{13i\theta } \right |=\sqrt{\left ( -1 \right )^{2}+\left ( \sqrt{3} \right )^{2}}[/tex]
Simplifying
[tex]r^{13}=2[/tex]
Taking root of 13 on both side, we get
[tex]r=2^{1/13}[/tex]
Reintroducing this 'r' value into the equation from [tex]r^{13}e^{13i\theta }=-1+\sqrt{3}[/tex], we get,
[tex]2e^{13i\theta }=-1+\sqrt{3}i[/tex]
Divide 2 on both side, we get
[tex]e^{13i\theta }=-\frac{1}{2}+\frac{\sqrt{3}}{2}i[/tex]
We can write [tex]e^{13i\theta }[/tex] as
[tex]\; \; \; \;cos13\theta +isin13\theta =-\frac{1}{2}+\frac{\sqrt{3}}{2}i[/tex]
[tex]\; \; \; \;cos13\theta=-\frac{1}{2}\;, \; \; \; \; \; \; \; sin13\theta =\frac{\sqrt{3}}{2}[/tex]
Angle must therefore be in the second quadrant.
[tex]13\theta=\pi -\frac{\pi }{3}=\frac{2\pi }{3}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;13\theta=\frac{2\pi }{3}+2\pi =\frac{8\pi }{3}[/tex]
[tex]\theta=\frac{2\pi }{39}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;\theta=\frac{8\pi }{39}[/tex]
So, second smallest positive argument = 8π/39.

What is the answer to this question?
The length of the rectangular pool is x + 7.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Area of a rectangular shape = Length × Width
Given that,
Area = x² + 15x + 56
Width = x + 8
Substituting,
x² + 15x + 56 = Length (x + 8)
Length = (x² + 15x + 56) / (x + 8)
Factorize x² + 15x + 56.
x² + 15x + 56 = (x + 7) (x + 8)
So length = x + 7
Hence the length of the pool can be represented as x + 7.

The time complexity average of this problem is O(n³). It involves three nested loops, each loop iterating n times. Therefore, the time complexity is O(n³).
The time complexity of this problem is O(n³). This problem involves three nested loops, each loop iterating n times. This means that the problem requires at least O(n³) time to complete. In the outer loop, which is the first loop, the value of i is initialized to 1 and then the loop iterates n times, meaning that the outer loop requires O(n) time. In the second loop, which is the nested loop, the value of j is initialized to 1 and then the loop iterates n times, meaning that the second loop requires O(n) time. In the third loop, which is the innermost loop, the value of k is initialized to 1 and then the loop iterates n times, meaning that the third loop requires O(n) time. Since the three loops are nested, the total time complexity of this problem is the product of the time complexities of the three loops, which is O(n³). Therefore, the time complexity of this problem is O(n³).
