The value of   Matrix B = [tex]\left[\begin{array}{ccc}9&17&3\\2&17&0\\3&22&8\end{array}\right][/tex]

Given : Matrix A = Matrix B

matrix A=      [tex]\left[\begin{array}{ccc}9&-2&3\\2&17&0\\3&22&8\end{array}\right][/tex]

The matrix A=      [tex]\left[\begin{array}{ccc}9&-2&3\\2&17&0\\3&22&8\end{array}\right][/tex] (according to the question)

Since it is given A=B

and substituting the given values of elements of B

matrix B=[tex]\left[\begin{array}{ccc}9&17&?\\?&?&?\\?&?&?\end{array}\right][/tex]

According to the property of equality of matrices,

When the matrices are given to be equal, their corresponding elements are also equal

so

b13 = 3

b21 = 2

b22 = 17

b23 = 0

b31 = 3

b32 = 22

b33 =8

Substituting the found out values in place of the question marks,

Matrix B = [tex]\left[\begin{array}{ccc}9&17&3\\2&17&0\\3&22&8\end{array}\right][/tex]

The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.

Speed is the time rate at which an object is moving along a path

Let the speed of southbound train is x miles/hour

so, northbound train has speed of x+10 miles/hour.

then, Speed of both train = Total distance/ total time

(x+10+x)=210/5

2x+10= 210/5

2x+10= 42

2x= 32

x= 16 miles per hour (southbound train)

northbound train:  16+10=26 miles per hour

A statement which best describes the function shown in the table is: B. exponential, there is a continual rate of decay or decrease.

An exponential function is a mathematical function whose numerical values (numerals) are generated by a constant that is raised to the power of an argument.

Given the following table:

X : -4        -1        2            4              5

Y :  16        2       0.25   0.0625    0.03125

Next, we would calculate the rate of decay for the y-values:

16/2 = 2/0.25 = 0.25/0.0625 = 0.0625/0.03125 = 8

Rule: The y-values constantly decreases by 1/4 or 0.25 of the previous number.

In conclusion, we can logically deduce that the function shown in the table is exponential, there is a continual rate of decay or decrease.

Answer:

1/9x

Step-by-step explanation:

The parenthesis around the 9x means that the -1 exponent goes to the whole thing (the 9x) To "fix" a negative exponent push the 9x across a fraction bar to make the exponent positive. When you push the 9x down across a fraction bar that leaves a 1 on top of the fraction, that has nothing to do with the 1 exponent. Its a 1 on top because when you push the 9x down there is nothing left on top so it is a 1.

(9x)^-1

= 1/9x

To be clear, this is a 1 one top and a 9x on the bottom of a fraction.

Step-by-step explanation:

Formula

[tex]\textsf{Area of a rectangle} = wl[/tex]

[tex]\textsf{Perimeter of a rectangle}=2(w+l)[/tex]

(where  [tex]w[/tex] is width and [tex]l[/tex] is length)

Given:

Substituting the given values into the formulae to create two equations:

[tex]\textsf{Equation 1}: \quad wl=160[/tex]

[tex]\textsf{Equation 2}: \quad 2(w+l)=52[/tex]

Rearranging Equation 1 to make w the subject:

[tex]\implies w=\dfrac{160}{l}[/tex]

Substituting expression for w into Equation 2 and solving for [tex]l[/tex]:

[tex]\implies 2\left(\dfrac{160}{l}+l\right)=52[/tex]

[tex]\implies \dfrac{160}{l}+l=26[/tex]

[tex]\implies 160+l^2=26l[/tex]

[tex]\implies l^2-26l+160=0[/tex]

[tex]\implies l^2-10l-16l+160=0[/tex]

[tex]\implies l(l-10)-16(l-10)=0[/tex]

The length of the fencing needed for the dog run will be 76 feet

The measure of the size of any object or the distance between the two endpoints will be termed the length.

Given that:-

Area of Dog Run = 240

Length of Dog Run = 30

The solution will be done as below:-

Width of Dog Run = 30 - x

Area of Dog Run:  30 * (30 - x) = 240

240 / 30 = 30 - x

8 = 30 - x

x = 24

Width of Dog Run = 8

How many feet of fencing will George need for the dog run?

Perimeter of Dog Run = 2Length + 2Width

Perimeter of Dog Run = (2 * 30) + (2 * 8)

Perimeter of Dog Run = 60 + 16

The perimeter of Dog Run = 76

Therefore the length of the fencing needed for the dog run will be 76 feet

Based on the calculations, the exact area of this rectangle is equal to 16√3 + 32 mm².

Mathematically, the area of a rectangle can be calculated by using this formula:

Area = Length × Width

Note: Radius (R) is equal to 2 mm.

Joining the center of the circles would form an equilateral triangle with side length of 2R. Also, the height of the equilateral triangle is given by:

Height = √2R² - R²

Height  = √3R

For the length and width of this rectangle, we have:

Length = R + 2R + R

Length  = 4R

Width = 2R + height of equilateral triangle

Width = 2R + √3R

Width = (2 + √3)R

Therefore, the area of a rectangle becomes:

Area = 4R × (2 + √3)R

Area = 4(2 + √3) × R²

Area = 4(2 + √3) × 2²

Area = (8 + 4√3) × 4

Area = 16√3 + 32 mm² ≡ a√3 + b

The correct answer is option C which is 3 sets of 2 negative tiles.

Multiplication is the process of determining the product of two or more numbers in mathematics.

We have the product of 3 and -2. We can represent this as 3 is equivalent to -2 negative tiles.

When we add -2 three times -2 - 2 -2 = -6 we will get -6 that is 3 sets of 2 negative tiles.

So when we multiply it by 3, we end with 3 sets of 2 negative tiles. This is because the order of the factors does not change the product.

The interquartile range defines the difference between the third and the first quartile.

Let's put this data set in ascending order:

24, 36, 48, 52, 52, 60, 72

The median is 52. The median of both the lower (1st quartile) and upper half (3rd quartile) of the data is 36 and 60.

Now we can subtract the first quartile from the third quartile (60 - 36) to get the interquartile range of 24.
