Answer:

See Explanation

Step-by-step explanation:

(a)For matrices A and D, given that: [tex]AD=I_m[/tex].

We want to show that [tex]\forall b \in R^m[/tex], Ax=b has a solution.

If Ax=b

Multiply both sides by D

[tex](Ax)D=b \times D\\\implies (AD)x=bD$ (Recall: AD=I_m)\\\implies I_mx=Db $ (Since I_m$ is the m\times m$ identity matrix)\\\implies x=Db[/tex]

This means that the system Ax=b has a solution.

(b)Matrix A has a pivot position in each row where each pivot is a different column. Therefore, A must have at least as many columns as rows.

This means A cannot have more rows than columns.

Answer: 24 black horses

Step-by-step explanation:

Let the number of black horses = bl and

The number of Brown horses = br

Total number of horses = d

Of the horses in the field, only 25% of them are brown. That is,

25% of d = br

0.25d = br ........ (1)

The remaining horses are black. Which will be 100% - 25% = 75%. That is,

75% of d = bl

0.75d = bl ........(2)

But according to the question, there are 16 more black horses than brown horses. That is,

bl = br + 16 ..... (3)

The total number of horses d will be

d = br + bl ...... (4)

Substitute bl in equation 3 into equation 4

d = br + br + 16

d = 2br + 16 ..... (5)

Substitutes equation (1) into the equation (5)

d = 2( 0.25d ) + 16

d = 0.5d + 16

Collect the like terms

d - 0.5d = 16

0.5d = 16

d = 16/0.5

d = 32

Substitute 32 for d in equation (2).

bl = 0.75 × 32

bl = 24 horses.

Therefore, 24 horses are black.

Answer:

-32x-22y

Step-by-step explanation:

4x + 2y - 6(6x - 4y)

Use distributive property

4x + 2y - 6(6x - 4y)

4x + 2y - 36x -24y

-32x-22y

Step-by-step explanation:

4x + 2y - 6(6x - 4y)

To remove the parenthesis multiply 6 by the terms in the parenthesis

That is

4x + 2y - 36x + 24y

Group like terms

4x - 36x + 2y + 24y

Simplify the terms

- 32x + 26y

Divide all terms by 2

we get

- 16x + 13y

hello,

pls find below the graph

we need to find the point of intersection between both lines

which is (4,3)

hope this helps

The solution for the given system of linear equations is (4, 3).

Given that, here is a graph of y=7-x for values x from 0 to 7.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

The given system of linear equations

y=7-x -------(I) and y=x-1 -------(II)

From equation (I) and (II),

7-x=x-1

⇒ 2x=8

⇒ x=4

So, y=7-x=3

Thus, (x, y)=(4, 3)

Therefore, the solution for the given system of linear equations is (4, 3).

Answer:

She didn't do the multiplication of 7 times the fraction 5/8 by using distributive property.

so the correct answer is the one that looks like:

Seven was not multiplied by StartFraction 5 over 8 EndFraction.

in your list of options.

Step-by-step explanation:

If one has a stack of seven books each [tex]2\frac{5}{8} \,\,in[/tex] thick, one should first convert the mixed number to an addition of an integer plus a fraction

[tex]2\frac{5}{8} =(2+\frac{5}{8})[/tex]

as she did, and then multiply 7 by the addition, making sure to use distributive property and multiply both terms:

[tex]7\,\,(2+\frac{5}{8})=7\,*\,12+7\,*\,\frac{5}{8}=14+\frac{35}{8}[/tex]

and she didn't do the multiplication of 7 times the fraction 5/8

[tex]\sin(\alpha+\beta) = -0.153[/tex]

Step-by-step explanation:

Let determine the angles behind each trigonometric expression:

[tex]\cos \alpha = -\frac{8}{17}[/tex]

[tex]\alpha = \cos^{-1}\left(-\frac{8}{17} \right)[/tex]

Given that [tex]180^{\circ}< \alpha < 270^{\circ}[/tex], the value of [tex]\alpha[/tex] is:

[tex]\alpha \approx 241.928^{\circ}[/tex]

[tex]\sin \beta = -\frac{4}{5}[/tex]

[tex]\beta = \sin^{-1}\left(-\frac{4}{5} \right)[/tex]

Given that [tex]270^{\circ}< \beta <360^{\circ}[/tex], the value of [tex]\beta[/tex] is:

[tex]\beta \approx 306.870^{\circ}[/tex]

The sine function of the sum of angles can be determined by the following identity:

[tex]\sin(\alpha + \beta)=\sin \alpha \cdot \cos \beta + \sin \beta \cdot \cos \alpha[/tex]

If [tex]\alpha \approx 241.928^{\circ}[/tex] and [tex]\beta \approx 306.870^{\circ}[/tex], then:

[tex]\sin (241.928^{\circ}+306.870^{\circ}) = (\sin 241.928^{\circ}) \cdot (\cos 306.870^{\circ}) + (\sin 306.870^{\circ})\cdot (\cos 241.928^{\circ})[/tex][tex]\sin(241.928^{\circ}+306.870^{\circ}) = -0.153[/tex]

Answer:

i. weight of wastage(kg) = 179.775 kg

ii. weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg

percentage of rice cultivated = 100 - 23.5 = 76.5%

Step-by-step explanation:

A land of 1000 sq. meter  is used to cultivate 765 kg of rice with wastage of 23.5%.

i. The wastage in percentage is 23.5% but the weight of the wastage in weight is  23.5% of 765 kg

weight of wastage = 23.5/100 × 765

weight of wastage = 17977.5/100

weight of wastage(kg) = 179.775 kg

ii. weight and percentage of rice cultivated.

weight of rice cultivated = 765 kg - 179. 775 kg = 585.225 kg

percentage of rice cultivated = 100 - 23.5 = 76.5%

Answer: y-2=1/4(x-1)

Step-by-step explanation:

The formula for point-slope is y-y₁=m(x-x₁). Since we are given the slope m, we can fill that in. We are also given the point (x₁,y₁). We can also fill that in.

y-2=1/4(x-1)

====================================================

Explanation:

You can factor x^2+6x+9 into (x+3)^2, which turns into 1(x - (-3) )^2 + 0

So y = x^2+6x+9 becomes y = 1(x - (-3) )^2 + 0

That matches with vertex form y = a(x-h)^2 + k

The vertex is (-3,0). The y coordinate of the vertex directly tells us the minimum value. We know we have a minimum because a = 1 is positive. If a < 0, then we'd have a max y value instead.

-------------------

Alternatively, compare y = x^2+6x+9 to the form y = ax^2+bx+c

We see that a = 1, b = 6, c = 9

The x coordinate of the vertex is

h = -b/(2a)

h = -6/(2*1)

h = -3

The x coordinate of the vertex is x = -3. Plug this into the original equation to find the y coordinate of the vertex

y = x^2 + 6x + 9

y = (-3)^2 + 6(-3) + 9

y = 9 - 18 + 9

y = -9 + 9

y = 0

The y coordinate of the vertex is y = 0. This is the smallest y output possible.

Answer:

y = 13

Step-by-step explanation:

Step 1: Distribute

3/2y - 3/2 = y + 5

Step 2: Subtract y on both sides

1/2y - 3/2 = 5

Step 3: add 3/2 on both sides

1/2y = 13/2

Step 4: Divide both sides by 1/2

y = 13

Answer:

y = 13.

Step-by-step explanation:

3/2(y-1) = y+5

3/2y - 3/2 = y + 5

3/2y - y = 5 + 3/2

1/2y = 6 and 1/2; 6.5; 13/2

y = 13.

To check out work...

3/2(13 - 1) = 13 + 5

3/2(12) = 18

3 * 6 = 18

18 = 18

On a number line, all you need to do is plot a point where it says 13. On a cartesian plane, you would have a horizontal line that expands infinitely in each direction, where y = 13.

Answer:

(-9, 0)

Step-by-step explanation:

To find the midpoint of the segment, we use the mathematical formula below;

(x,y) = {(x1+x2)/2 , (y1+y2)/2}

From the question;

(x1,y1) = (10,16)

(x2,y2) = (-28,-16)

Substituting these values into the equation we wrote above, we have;

(x,y) = (10-28)/2 , (16-16)/2

(x,y) = (-18/2, 0/2) = (-9,0)

Answer:

x = 23

Step-by-step explanation:

CU + UB = CB

Since U is the midpoint that means CU = UB = 18

18+ 18 = 2x-10

36 = 2x-10

Add 10 to each side

36+10 = 2x

46 =2x

Divide by 2

23 = x

Answer:

Step-by-step explanation:

CB/2 = CU

CB = (2)CU

2x - 10 = (2)18

2x - 10 = 36

Add 10 on both sides.

2x = 46

Divide both sides by 2.

x = 23

The value of angel A = 40 and side= 9.3 cm

The ratio of the side and the corresponding angle of a triangle is equal to the diameter of the circumcircle of the triangle. The sine law is can therefore be given as,

a/ sin A= b/ sin B= c/ sin C

The law of sines formula is used for relating the lengths of the sides of a triangle to the sines of consecutive angles. It is the ratio of the length of the side of the triangle to the sine of the angle thus formed between the other two remaining sides. The law of sines formula is used for any triangle apart from SAS triangle and SSS triangle. It says,

a/sin A = b/sin B = c/sin C

where,

a, b, and c are the lengths of the triangle

A, B, and C are the angles of the triangle.

Using angle sum property,

<A + <B + <C= 180

<A + 110 + 30 = 180

<A = 180- 140

<A= 40

Now, Using  law

a/ sin A= b/ sin B= c/ sin C

12/sin 40 = c/ sin 30

c= 9.3

Answer:

Average speed of passenger aircraft in 1978 is 408.9 mph

Step-by-step explanation:

Here, in the question, we are tasked with giving the value of the average speed of the passenger aircraft in the US for the year 1978, given that it is a certain multiple of the value in 1960.

So what we will be doing here is to get the value of the average speed and it can be gotten by multiplying the average speed in 1960 by the multiple to which the speed is, now in 1978.

From the question, we can write a formula for this;

Average speed of passenger aircraft in 1978 = 1.74 * average speed of passenger aircraft in 1960

From the question, we have that the average speed of passenger aircraft in 1960 = 235 mph

Thus,

Average speed of passenger aircraft in 1978 = 1.74 * 235 = 408.9 mph
