Answer:

[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]

Step-by-step explanation:

Given the matrix A

[tex]\left[\begin{array}{ccc}-3&8&5\\-1&2&3\end{array}\right][/tex]

We are to find the matrix that results from the elementary row operations represented by −3R2+4R1

R2 means row 2

R1 means row 1

Applying the elementary row operation will change the second row of the matrices.

For the first column, second row (a₂₁)

If R1 = -3, R2 = -1

a₂₁ = -3R2+4R1

a₂₁ = -3(-1)+4(-3)

a₂₁ = 3-12

a₂₁ = -9

For a₂₂

If R1 = 8, R2 = 2

a₂₂ = -3R2+4R1

a₂₂ = -3(2)+4(8)

a₂₂ = -6+32

a₂₂ = 26

For a₂₃

If R1 = 5, R2 = 3

a₂₃ = -3R2+4R1

a₂₃ = -3(3)+4(5)

a₂₃ = -9+20

a₂₃ = 11

Hence the resulting matrix will be:

[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]-3R2+4R1

Answer:

[-3       5  2]

[-36  23  -1]

Step-by-step explanation:

Note abidemiokin did the steps right just has the "given" wrong.

Given the matrix A

[-3  5  2]

[ 8 -1   3]

We are to find the matrix that results from the elementary row operations represented by −3R2+4R1

R2 means row 2

R1 means row 1

Applying the elementary row operation will change the second row of the matrices.

For the first column, second row (a₂₁)

If R1 = -3, R2 = 8

a₂₁ = -3R2+4R1

a₂₁ = -3(8)+4(-3)

a₂₁ = -24-12

a₂₁ = -36

For a₂₂

If R1 = 5, R2 = -1

a₂₂ = -3R2+4R1

a₂₂ = -3(-1)+4(5)

a₂₂ = 3+20

a₂₂ = 23

For a₂₃

If R1 = 2, R2 = 3

a₂₃ = -3R2+4R1

a₂₃ = -3(3)+4(2)

a₂₃ = -9+8

a₂₃ = -1

Hence the resulting matrix will be:

[-3       5  2]

[-36  23  -1]   -3R2+4R1

Answer:

[tex]Probability = \frac{2}{35}[/tex]

Step-by-step explanation:

Given

[tex]Total = 70[/tex]

First, we need to list the multiples of 5

[tex]M_5 = \{5,10,15,20,25,30,35,40,45,50,55,60,65,70\}[/tex]

Then, multiples of 3[tex]M_3 = \{3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69\}[/tex]

Next, is to list out the common elements in both

[tex]M_3\ n\ M_5 = \{15,30,45,60\}[/tex]

[tex]n(M_3\ n\ M_5) = 4[/tex]

The required probability is then calculated as thus:

[tex]Probability = \frac{n(M_3\ n\ M_5)}{Total}[/tex]

[tex]Probability = \frac{4}{70}[/tex]

[tex]Probability = \frac{2}{35}[/tex]

Answer:

the first one, if you solved it using the calculator, the answer will be 0

Answer:

18+30 = 48

6(3+10) = 78

so they're not equal

Step-by-step explanation:

to be equal we have to change 6(3+10) to 6(3+5)

18+30 = 48

6(3+5) = 48

now they're equal

15 coops are needed for 108 pigeons

The unitary method is  a technique for solving a problem but first finding the value of a single unit , and then finding the necessary value by multiplying the single unit value

using  unitary method

Total pigeon = 108

each coop can hold = 7 pigeons

7 pigeons are held by = 1 coop

108 pigeons will be held by = 108 / 7 = 15.43 =15

15 coops are needed for 108 pigeons

There are 108 pigeons that need pigeon coops, each coop can hold up to 7 pigeons, coops are required for all 108 pigeons.

"Pigeons are gentle, plump, small-billed birds with a skin saddle (cere) between the bill and forehead."

"Pigeon houses are also sometimes referred to as "coops" although the word seems to have originally applied to the breeding pens inside the housing."

Total number of pigeons that needed coops [tex]=108[/tex]

Number of pigeons each coop can hold [tex]=7[/tex]

Number of coops required

[tex]=\frac{108}{7} \\=15.42\\=16[/tex]

Hence, we need approximately 16 coops for all 108 pigeons.

Answer:

m<3 = 66°

Step-by-step explanation:

<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.

The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.

Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:

m<3 = ½(40 + 92)

m<3 = ½(132)

m<3 = 66°

The measure of m<3 = 66°

Since  arc WX = 40' and arc Y Z = 92

So we know that

The measure of an internal angle should be equivalent to half the sum of the measure of the arcs intercepted.

So based on this

m<3 =0.50 (40 + 92)

m<3 = 0.50(132)

m<3 = 66°

hence, The measure of m<3 = 66°

Answer:

  yes

Step-by-step explanation:

Yes, you can find the distance between two lines using the formula for the distance to a line.

In general, the notion of distance between two lines only make sense when the lines are parallel.

The usual formula for the distance between a point (x, y) and the line ...

  ax +by +c = 0

is ...

  d = |ax +by +c|/√(a^2 +b^2)

Two lines that are parallel will differ only in their values of 'c'. That is, if the two lines are ...

we can arrive at the formula by considering a point (x, y) such that it satisfies the equation for line 2: ax +by +c2 = 0. The distance of that point from line 1 will be ...

  d = |ax +by +c1|/√(a^2 +b^2)

Since we can add or subtract 0 from anything without changing its value, we choose to subtract 0 from the numerator:

  d = |(ax +by +c1) -(ax +by +c2)|/√(a^2 +b^2)

Simplifying gives ...

  d = |c1 -c2|/√(a^2 +b^2)

Answer:

Number of bottles = 6

Number of cans = c

Step-by-step explanation:

Given that:

Container for selling water :

17 oz bottle

11 oz can

Let number of bottles = b

Number of cans = c

b + c = 11 - - - (1)

17b + 11c = 157 - - - (2)

b = 11 - c

Substitute into (2)

17(11 - c) + 11c = 157

187 - 17c + 11c = 157

187 - 6c = 157

-6c = 157 - 187

-6c = -30

c = 30/6

c = 5

From ; b = 11 - c

b = 11 - 5

b = 6

Hence,

Number of bottles = 6

Number of cans = c

6 bottles and 5 cans

[tex]\displaystyle \frac{5}{6}\cdot \frac{-8}{15}=-\frac{4}{9}[/tex]

Step-by-step explanation:

Fraction Multiplying

The product of two fractions can be obtained by multiplying their numerators and denominators separately. Then, simplify and show the result.

We are given the product:

[tex]\displaystyle \frac{5}{6}\cdot \frac{-8}{15}[/tex]

Multiply as directed:

[tex]\displaystyle \frac{5}{6}\cdot \frac{-8}{15}=\frac{5*(-8)}{6*15}=-\frac{40}{90}[/tex]
