Answer:

169

Step-by-step explanation:

Perimeter of a rectangle= 2(length+breath)

2(18 + 8)

2(26)

52.

A square has four equal sides.

The length will be determined by dividing 52 by 4

\(52 \div 4 = 13\)

The length is 13.

Since the area of a square is

\( {l}^{2} = {13}^{2} \)

L is length.

The answer is

\( {169}^{2} \)

The value of "a" that makes the set of vectors independent is 1.

In 3-dimensional space, a set of vectors is said to be independent if any one of the vectors cannot be represented as a linear combination of the other vectors.

We may utilize the idea of determinants to determine the value of "a" such that the set of vectors "(1, 0, -2), (3, 2, a), (-3, -5, 1)" is independent.

The linear dependence or independence of the given vectors can be assessed using the determinant of a 3x3 matrix, whose columns are the given vectors. If the vectors are linearly dependent, the determinant will be 0; if they are independent, it will be non-zero.

The determinant can be calculated as follows:

| 1 0 -2 |

| 3 2 a |

| -3 -5 1 | = 0

Expanding the determinant along the first row, we get:

1 * ((2 * 1) - (a * -5)) - 0 * ((-3 * 1) - (-2 * -5)) + (-2 * (2 * -3 - a * -3)) = 0

2 - 5a - 6 + 10 + 6a = 0

Expanding the equation and solving for a, we get:

8a = 8

a = 1

Thus, the set of vectors {(1, 0, -2), (3, 2, 1), (-3, -5, 1)} is independent.

So, the value of "a" that makes the set of vectors independent is 1.

Answer:

Step-by-step explanation:

\(\lim_{8x \to \infty} 9_y=10\)

The polynomial value equations are solved and the solutions are :

a) ( x - 2 )² = x² - 4x + 4

b) ( x - 4 ) ( x + 4 ) = x² - 16

c) ( x² + 2x ) ( -2x + 8 ) = -2x³ + 4x² + 16x

Given data ,

Let the equation be represented as A = (x - 2)²

Using the square of a binomial formula, (x - y)² = x² - 2xy + y², we can apply it to (x - 2)²:

(x - 2)² = x² - 2(x)(2) + 2²

A = x² - 4x + 4

Hence the polynomial (x - 2)² simplifies to x² - 4x + 4

b)

Let the equation be represented as A = (x - 4)(x + 4)

Using the distributive property, we can multiply (x - 4)(x + 4):

(x - 4)(x + 4) = x(x) + x(4) - 4(x) - 4(4)

A = x² + 4x - 4x - 16

A = x² - 16

Hence the polynomial (x - 4)(x + 4) simplifies to x² - 16

c)

Let the equation be represented as A = (x² + 2x)(-2x + 8)

Using the distributive property, we can multiply (x² + 2x)(-2x + 8):

(x² + 2x)(-2x + 8) = x²(-2x) + x²(8) + 2x(-2x) + 2x(8)

A = -2x³ + 8x² - 4x² + 16x

A = -2x³ + 4x² + 16x

Hence the polynomial (x² + 2x)(-2x + 8) simplifies to -2x³ + 4x² + 16x

Step-by-step explanation:

Answer:

$5000 is how much he borrowed or the "principle" amount.

Step-by-step explanation:

The formula for simple interest is: I = p * r * t

where I = the interest charged, p = principle or amount borrowed, r = the annual rate charged (changed from a percent to decimal by dividing by 100) and t = time (must be expressed in year)

So, I = prt

750 = p * .05 * 3            (here, 3 * .05 = 0.15)

750 = 0.15p    (now you need to solve for p by dividing both sides of the                          

0.15    0.15                 equation by .15

5000 = p

Answer:

A'(4, -3) ; T'(-1, 4)

Step-by-step explanation:

Multiply the coordinates by 1/2, or divide them by 2 to get the new points.

A(8, -6) ⇒ A'(4, -3)

T(-2, 8) ⇒ T'(-1, 4)

To find the distance between points A and B, we can use trigonometry and the given information.

Let's label the distance between A and B as "d". We know that point C is 94.4 meters away from point A. From angle A, we have the measure of 72°, and from angle C, we have the measure of 30°.

Using trigonometry, we can use the tangent function to find the value of "d".

tan(72°) = d / 94.4

To solve for "d", we can rearrange the equation:

d = tan(72°) * 94.4

Using a calculator, we can evaluate the expression:

d ≈ 4.345 * 94.4

d ≈ 408.932

Therefore, the distance between points A and B is approximately 408.932 meters.

Triangle WVX is similar to triangle WZY. If two traingles are similar, it means that the ratio of their corresponding sides is equal. This means that

WV/WZ = VX/ZY = WX/WY

From the information given,

WX = 7, WY = a, WV = 6, VZ = a - 9

WZ = WV + VZ = 6 + a - 9 = a - 3

Thus, we have

6/(a - 3) = 7/a

By crossmultiplying, it becomes

6 x a = 7(a - 3)

6a = 7a - 21

7a - 6a = 21

a = 21

Since WY = a, then

WY = 21

The required coefficients are:4, -1, -11, and 7.

Coefficients refer to the numerical values that are assigned to variables in mathematical equations, models, or formulas. They indicate the relative importance or contribution of each variable in the equation. Coefficients are used to determine the relationship between variables and are often estimated through statistical analysis or optimization techniques.

In algebraic equations, coefficients are the numbers multiplied by variables. For example, in the equation 2x + 3y = 5, the coefficients are 2 and 3.

In statistical models, such as linear regression, coefficients represent the slopes or weights assigned to the predictor variables. These coefficients indicate how much the response variable is expected to change for a unit change in the corresponding predictor variable, assuming all other variables are held constant.

We need to consider the polynomial:

(4mn^2n - 2mn + 6) + (6mn^2 - 1) - (mn^2 - 2 + 9mn)

To combine the like terms and find the coefficients of each term, we can write the polynomial in the following form:

4mn^2n - 2mn + 6 + 6mn^2 - 1 - mn^2 + 2 - 9mn

Taking the coefficients of the terms with "mn^2"4mn^2n - mn^2

Taking the coefficients of the terms with "mn"-2mn - 9mn = -11mn

Taking the coefficients of the constant terms6 + 2 - 1 = 7

Therefore, the required coefficients are:4, -1, -11, and 7.

Typically, this process involves the retailer (or team of employees) walking through the retailer's warehouse and storefront, counting each item. Information is captured manually using pen and paper or electronically using a mobile device.

Create a storage location map showing each shelf, bin, drawer, receiving dock, and return area. Place geographic divisions, not product lines, between each storage area. Let's start counting! After each counter completes a certain range, allow a manager or someone else to check the count.

The joint relative Frequency of students who do not like to run and enjoy swimming, based on the given two-way frequency table, is approximately 62.16%.

The joint relative frequency of students who do not like to run and enjoy swimming, we need to find the intersection of the row and column corresponding to those categories in the two-way frequency table.

Given the following information from the table:

Likes running: 28

Does not like running: 46

Column totals: 74

Enjoys swimming: 62

Enjoys cycling: 90

Row totals: 110

The joint relative frequency, we divide the number of students who do not like running and enjoy swimming by the total number of students:

Joint relative frequency = (Number of students who do not like running and enjoy swimming) / (Total number of students)

From the table, the number of students who do not like running and enjoy swimming is given as 46.

Total number of students is given as 74.

Joint relative frequency = 46 / 74

Calculating this value, we find that the joint relative frequency is approximately 0.6216, which is equivalent to 62.16%.

Therefore, the joint relative frequency of students who do not like to run and enjoy swimming is approximately 62.16%.

In conclusion, the joint relative frequency of students who do not like to run and enjoy swimming, based on the given two-way frequency table, is approximately 62.16%.
