According to the given equation :

The given matrix can be represented as:⎡x  3y⎤⎣x  -3y⎦

So, x-determinant = 24 , y-determinant = 0 and system determinant = 4.

Given the system of equations as:

x + 3y = 5

x - 3y = -1

The given matrix can be represented as:

⎡x  3y⎤⎣x  -3y⎦

We need to find the x-determinant, y-determinant and system determinant.

Let us represent each matrix by A11, A12, A21, A22 and so on.

x-determinant: It is the determinant of matrix obtained by replacing the first column by the column on the right-hand side of the given matrix.

x-determinant = |5 -1| |-1 5|

= 5*5 - (-1)*(-1) = 25 - 1 = 24

y-determinant: It is the determinant of matrix obtained by replacing the second column by the column on the right-hand side of the given matrix.

y-determinant = |1 -1| |-1 1|

= 1*1 - (-1)*(-1) = 0

system determinant: It is the determinant of matrix obtained by replacing both the columns by the columns on the right-hand side of the given matrix.

system determinant = |5 -1| |1 -1|

= 5 - 1 = 4

Answer:

Greater.

Step-by-step explanation:

The in the function , the square root term has to give a real number if is to be real. This can only happen if because if then will give a complex number and therefore will not be real.

Thus, the domain for f(x) is all real numbers greater than or equal to 2.

Answer:

The domain for f(x) is all real numbers greater than or equal to 2.

Step-by-step explanation:

Given function:

\(f(x)=2x^2+5 \sqrt{x-2}\)

The domain of a function is the set of all possible input values (x-values).

As the square root of a negative number cannot be taken:

\(\implies x-2\geq 0\)

Therefore:

\(\implies x-2+2\geq 0+2\)

\(\implies x\geq 2\)

Therefore, the domain of the given function is greater than or equal to 2.

The trigonometric ratio for the tangent of an angle indicates that the tangent of the angle ∠B expressed as an improper fraction is expressed in the form;

tan(∠B) = \(2\frac{2}{39}\)

The tangent of an angle in a triangle is the ratio of the facing side to the adjacent side of the triangle.

The type of triangle in the figure with an interior angle of 90 degrees is a right triangle, therefore, according to the Pythagorean Theorem, we get;

(AC)² + (AB)² = (BC)²

Therefore, we get;

(AC)² + 39² = 89²

(AC)² = 89² - 39² = 6400

AC = √(6400) = 80

The tangent of an angle is the ratio of the opposite side to the adjacent side, therefore;

tan(m∠B) = AC/AB

tan(m∠B) = 80/39 = \(2\frac{2}{39}\)

When testing the null hypothesis with an alpha value of 0.05, the critical value will be larger than if you were testing with an alpha value of 0.01.

If you are testing the null hypothesis with an alpha value of 0.05, the critical value will be smaller than if you were testing the alpha value of 0.01. This is because a smaller alpha value means a more stringent test of significance, which requires stronger evidence to reject the null hypothesis.

Therefore, the critical value is larger for a smaller alpha value to reflect the higher level of evidence required for rejection. Conversely, a larger alpha value allows for a less stringent test of significance, requiring weaker evidence to reject the null hypothesis, which results in a smaller critical value.

Answer:

y=-2x+15

Step-by-step explanation:

Hi there!

We are given that m=-2, b=15, and we want to write the equation of the line, given these values

We can write the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, since we are given the values of both m and b.

Since we know the values of m and b (-2 and 15 respectively), we can substitute those numbers in as the variables they equal to.

Substitute -2 as m:

y=-2x+b

Substitute 15 as b:

y=-2x+15

The equation of a circle having endpoints of diameter as (4,9) and (4,-3) is (x - 4)² + (y - 3)² = 36.

The "center" of circle is called as midpoint of diameter.

The "x-coordinate" of "mid-point" is = (4+4)/2 = 4, and

The "y-coordinate" of "mid-point" is = (9+(-3))/2 = 3.

So, center of circle is (4,3),

The radius of circle is half the length of the diameter, which is distance between two endpoints of diameter. We find distance using distance formula:

⇒ distance = √((x₂ - x₁)² + (y₂ - y₁)²), where (x₁,y₁) and (x₂,y₂) are "end-points" of diameter.

⇒ distance = √((4 - 4)² + (9 - (-3))²)

⇒ √(144) = 12.

So, radius is 6.

The equation of circle with center (h,k) and radius "r" is : ⇒ (x - h)² + (y - k)² = r²,

Substituting the values

We get,

⇒ (x - 4)² + (y - 3)² = 6²,

⇒ (x - 4)² + (y - 3)² = 36,

Therefore, the equation of the circle is (x - 4)² + (y - 3)² = 36.

\(\sqrt{65}\)

Step-by-step explanation:

the absolute value of the complex number a + bi is

| a + bi | = \(\sqrt{a^2+b^2}\)

A)  annual percentage increase in the winner's check over this period is approximately 11595652.17%.

B)   if the winner's prize increases at the same rate, it will be approximately $3,651,682,684.48 in 2055.

a. To find the annual percentage increase in the winner's check over this period, we can use the formula:

Annual Percentage Increase = ((Final Value - Initial Value) / Initial Value) * 100

First, let's calculate the annual percentage increase in the winner's check from 1899 to 2020:

Initial Value = $23
Final Value = $2,670,000

Annual Percentage Increase = (($2,670,000 - $23) / $23) * 100

Now, we can calculate this value using the given formula:

Annual Percentage Increase = ((2670000 - 23) / 23) * 100 = 11595652.17%

Therefore, the annual percentage increase in the winner's check over this period is approximately 11595652.17%.

b. If the winner's prize increases at the same rate, we can use the annual percentage increase to calculate the prize money in 2055. Since we know the prize money in 2020 ($2,670,000), we can use the formula:

Future Value = Initial Value * (1 + (Annual Percentage Increase / 100))^n

Where:
Initial Value = $2,670,000
Annual Percentage Increase = 11595652.17%
n = number of years between 2020 and 2055 (2055 - 2020 = 35)

Now, let's calculate the prize money in 2055 using the given formula:

Future Value = $2,670,000 * (1 + (11595652.17 / 100))^35

Calculating this value, we find:

Future Value = $2,670,000 * (1 + 11595652.17 / 100)^35 ≈ $3,651,682,684.48

Therefore, if the winner's prize increases at the same rate, it will be approximately $3,651,682,684.48 in 2055.

\(A = B^-1 * BC\)

Since B is invertible, it can be used to solve the equation.

1. Calculate the inverse of B, \(B^-1\).

2. Multiply\(B^-1\) with BC, to obtain A.

Assuming that AB and C are square matrices and B is invertible, the equation AB=BC can be solved for A. To do this, we first need to calculate the inverse of B, \(B^-1\). The inverse of a matrix is defined as the matrix which when multiplied to the original matrix, yields the identity matrix. Once we have the inverse of B, we can use it to solve the equation by multiplying \(B^-1\) with BC, which will give us A. This works because when we multiply a matrix by its inverse, the result is always the identity matrix. Hence, by multiplying the inverse of B with BC, we can obtain A.

The amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches

Let the three dimensions(height, length, width) be x, y,z units respectively.

The surface area of the cuboid is given by

\(S = 2(a\times b + b\times c + c\times a)\)

A box is usually in shape of a cuboid.

For this case, its dimensions are 10 inches, 10 inches, and 6 inches.

The amount of wrapper we need is approx same as the area of its surface (assuming we're going to measure the paper needed in terms of its area).

Thus, we get:

Amount of the paper we need to wrap the considered box = surface area of that box = surface area of cuboid of dimension 10 inch by 10 inch by 6 inches = S (say), then:

\(S = 2(10\times 10+ 10\times 6 + 6\times 10)\\S = 440\)(in sq. inches)

The expression that represents the width of the rectangle in yards, given the area and length, is option C: 4x^3y^4.

To determine the width of the rectangle, we divide the area by the length. In this case, the area is 36x^(7y^(5)) and the length is 9x^4y. Dividing the area by the length will cancel out the common factors and leave us with the remaining factors representing the width.

When we divide 36x^(7y^(5)) by 9x^4y, we divide the coefficients (36/9 = 4) and subtract the exponents of the variables (x^(7-4) = x^3, y^(5-1) = y^4). Therefore, the width of the rectangle is 4x^3y^4, which matches option C.

The equation can be simplified and written in a slope-intercept form as: \(y=18 \sqrt{3} x-6(\sqrt{3} \pi-1)\)

To find the equation:

When we differentiate the function \(y=6 \sec (x)-12 \cos (x)\), we get:

\(\begin{aligned}y^{\prime} &=\frac{d}{d x}(6 \sec (x)-12 \cos (x)) \\&=6 \frac{d}{d x}(\sec (x))-12 \frac{d}{d x}(\cos (x)) \\&=6 \sec (x) \tan (x)+12 \sin (x)\end{aligned}\)
