Yes, the inverse of a matrix exists if the determinant of the matrix is -13.

What is a matrix?

Linear equations are expressed using matrices, which are ordered rectangular arrays of numbers. Columns and rows make up a matrix. Mathematical operations like addition, subtraction, and matrix multiplication can also be done on matrices. If there are m rows and n columns, the matrix is represented as m × n matrix. The inverse of a matrix is available only for square matrices.

Now the determinant is a value that is associated with a square matrix.

The product of all the elements in any row or column and their corresponding co-factors is the determinant of a matrix.

For an inverse matrix to exist, the determinant of the matrix should not be zero. This is because the determinant of the inverse matrix is the inverse of the determinant of the original matrix.

If the determinant is zero, then the determinant of the inverse matrix will be 1/0, which is undefined.

So, as long as the determinant is not equal to zero, the inverse matrix exists.

Therefore the inverse of a matrix exists if the determinant of the matrix is -13.

Answer: 35m2

Step-by-step explanation:took the test and i got it right

An isosceles trapezoid with a short base of 3 meters and a height of 5 meters then the area of the trapezoid is 35 m²

What is the area of the trapezoid?

To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

We can start by finding the length of the long base. Since the trapezoid is isosceles, we know that the length of the portion of the large base from the left vertex to the perpendicular is equal to the length of the portion from the right vertex to the perpendicular. Let's call the length of the long base "x":

x = 4 + 7 = 11 meters

Now we can use the formula for the area of a trapezoid:

Area = (1/2) * (short base + long base) * height

Substituting the values we have:

Area = (1/2) * (3 + 11) * 5

Area = 7 * 5

Area = 35 m²

Therefore, the area of the trapezoid is 35 m².

If f(1) = 0, what are all the roots of the function ? use the remainder theorem.

Answers

By using synthetic division, we can find all the roots of the function f(x) = x³ + 3x² - x - 3 and determine that the roots are 1, -1, and -3.

A root of a function is a value for x that makes the function equal to zero.

In this case, we have a function f(x) = x³ + 3x² - x - 3 and we know that f(1) = 0. To find all the roots of this function, we can use the remainder theorem.

The remainder theorem states that if we divide a polynomial by a linear expression (such as x - a), the remainder will be equal to the value of the polynomial at that value of x (a). In other words, if we write f(x) = (x - a)q(x) + r, where r is the remainder, then f(a) = r.

So, if we divide our function f(x) by x - 1, the remainder will be equal to f(1), which we know is zero. Therefore, (x - 1) is a factor of f(x), and the function has a root at x = 1.

Next, we can divide f(x) by (x - 1) to get a quotient, q(x), and a new remainder, r. We can repeat this process, dividing q(x) by another linear expression until we have no more remainders.

The roots of f(x) will be the values of x that we used as factors in each step of the division process.

This process of dividing a polynomial by a linear expression to find its roots is called synthetic division.

The inverse of function is  f(x) = (x - 4)³/8 + 3

What is inverse function?

A function that reverses the results of another function is known as an inverse function. If y = f(x), then x = g(y), then a function g is the opposite of a function f. To put it another way, applying f and then g is equivalent to doing nothing. This can be expressed as g(f(x)) = x in terms of how f and g are made up.

Given g(x) = 2(∛x-3)+4

let g(x) = y

y = 2(∛x-3)+4

change the variables since options are in form of x

x =  2(∛y-3)+4

simplify for y

subtract 4 from both side

x - 4 = 2(∛y-3)+4 - 4

x - 4 = 2(∛y-3)

divide both side by 2

(x - 4)/2 = (2(∛y-3))/2

(x - 4)/2 = (∛y-3)

cube both side

((x - 4)/2)³ = ((∛y-3))³

(x - 4)³/8 = y - 3

(x - 4)³/8 + 3 = y

Hence  the value f(x) =  (x - 4)³/8 + 3 .

what is convergence radius calculator

Answers

A convergence radius calculator is a tool used in calculus to calculate the radius of convergence for a power series using the ratio test.

To calculate the convergence radius of a power series, one can use a formula known as the "ratio test". The ratio test involves taking the limit of the absolute value of the ratio of successive terms in the series, as n approaches infinity. If this limit exists and is less than 1, then the series converges absolutely. The convergence radius can then be found as the reciprocal of this limit.

For example, given the power series:

∑(n=0 to infinity) [tex](x-2)^n / n^2[/tex]

we can use the ratio test to find the convergence radius as follows:

[tex]|(x-2)^(n+1) / (n+1)^2| / |(x-2)^n / n^2|[/tex]

= [tex]|(x-2) / (n+1)|^2 * (n^2 / (x-2)^2)[/tex]

= [tex](n^2 / (n+1)^2) * (1 / (x-2)^2)[/tex]

= [tex]n^2 / ((n+1)^2 * (x-2)^2)[/tex]

Taking the limit of this expression as n approaches infinity, we get:

[tex]lim(n- > ∞) (n^2 / ((n+1)^2 * (x-2)^2))[/tex]

= [tex]1 / (x-2)^2[/tex]

Since this limit exists and is less than 1 for all x except x=2, the power series converges absolutely for all values of x within a radius of [tex]1/(x-2)^2[/tex] centered at x=2. Therefore, the convergence radius of the power series is 1.

What are Vectors?

Quantities with the independent characteristics of magnitude and direction are called vectors.

Given:

u = (-3, 8) and v = (-14, 6)

So, 3u = (-9, 24) and 2v = (-28, 12)

3u - 2v = (-9+28, 24-12)

3u - 2v = (19, 12)

Magnitude of 3u - 2v = √19² + 12²  = √505 units

2u = (-6, 16) and 3v = (-42, 18)

2u - 3v = (36, -2)

Magnitude = √36² + (-2)²  = √1300 units

u = (-3, 8) and 4v = (-56, 24)

u + 4v = (-59, 32)

Magnitude = √(-59)² + 32²  = √4505  units

An equation of the line that passes through the points (4, -3) and (8,5) is y + 3 = 2(x - 4).

What is the point-slope form?

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

m represents the slope.x and y are the points.

At data points (4, -3), a linear equation of this line can be calculated by using the point-slope form as follows:

You have 71/2 minutes to complete three rock climbing walls do you normally climb each wall in 155 seconds do you have enough time to climb all three walls.

Answers

In order to finish the task in the allotted time, you would therefore need to ascend more quickly or decide to only climb the first two walls.

What do the two definitions of "minute" mean?

The Latin term minute, which means "small," is the root of both the adjective instant (my-NOOT), which denotes something that is incredibly small, and the substance minute (MIN-it), which denotes 60 seconds of time. Although the two terms have different pronunciations, they both refer to small sizes.

We can compute the overall time needed to scale all three barriers and compare it to the time available, which is 71/2 minutes or 450 seconds, to determine if you have enough time.

One wall takes 155 seconds to scale, so climbing three walls would take:

3 walls x 155 seconds per wall = 465 seconds

You wouldn't have enough time to scale all three walls inside the allotted time restriction because 465 seconds is longer than the amount of time that is accessible, which is 450 seconds.

How do you find the two largest numbers in an array in Matlab?

Answers

To find the two largest numbers in an array in Matlab, you can use the sort function and indexing to access the two largest elements.

Here's an example:

array = [3, 8, 2, 10, 5];

sorted_array = sort(array, 'descend');

largest_number = sorted_array(1);

second_largest_number = sorted_array(2);

In this example, we have an array of numbers called array. We use the sort function to sort the array in descending order, which means that the largest numbers will be at the beginning of the array. The resulting sorted array is assigned to a new variable called sorted_array.

We then use indexing to access the first and second elements of the sorted array, which will be the two largest numbers. These numbers are assigned to the variables largest_number and second_largest_number, respectively.

It's important to note that if the array contains duplicate values, this method will return the two largest unique values. If you want to find the two largest values including duplicates, you can use the max function twice with the 'omitnan' parameter to handle any NaN values in the array:

array = [3, 8, 2, 10, 5, 10];

largest_number = max(array, [], 'omitnan');

array_without_largest_number = array(array < largest_number);

second_largest_number = max(array_without_largest_number, [], 'omitnan');

In this example, we first find the largest number in the array using the max function with the 'omitnan' parameter to ignore any NaN values. We then create a new array that excludes the largest number, and use the max function again to find the second largest number in the new array.
