La longitud de las diagonales del rectángulo con área de 15 centímetros cuadrados se describe con [tex]d = \frac{\sqrt{x^{2}+225}}{x}[/tex].

El área de rectángulo que mediante la ecuación de área estándar, mientras sus diagonales pueden ser descritas mediante el teorema de Pitágoras, los cuales se describen a continuación:

Área

[tex]A = x\cdot y[/tex] (1)

Diagonal

[tex]d = \sqrt{x^{2}+y^{2}}[/tex] (2)

Donde:

Despejamos [tex]y[/tex] en (1):

[tex]y = \frac{A}{x}[/tex]

Luego, aplicamos la fórmula a (2) para eliminar la variable:

[tex]d = \sqrt{x^{2}+\frac{A^{2}}{x^{2}} }[/tex]

Simplificamos la expresión resultante: ([tex]A = 15\,cm^{2}[/tex]):

[tex]d = \frac{\sqrt{x^{2}+A^{2}}}{x}[/tex]

[tex]d = \frac{\sqrt{x^{2}+225}}{x}[/tex]

0.00000604 = 6.04 × 10 ⁻⁶

Numbers in scientific notation get written in the form 1.23... × 10ⁿ, so it's a matter of counting how many times you multiply or divide by 10 in order to move the decimal point to the right position.

The number 0.00000604 has 3 significant digits, so you want to end up with 6.04, and to do that you need to move the decimal point 6 places to the right:

0.00000604

= 0.0000604 × 10 ⁻¹

= 0.000604 × 10 ⁻²

= 0.00604 × 10 ⁻³

= 0.0604 × 10 ⁻⁴

= 0.604 × 10 ⁻⁵

= 6.04 × 10 ⁻⁶

Answer:

16, 8, 36

Step-by-step explanation:

To solve for x for the first answer, multiply 4 by y

[tex]y = \frac{x}{4} \\\\y (4) = x\\\\x = 4(4)\\ x= 16[/tex]

To solve for x for the second answer, multiply 2 by y

[tex]y = \frac{x}{4} \\\\y (4) = x\\\\x = 2(4)\\ x= 8[/tex]

To solve for x for the third answer, multiply 9 by y

[tex]y = \frac{x}{4} \\\\y (4) = x\\\\x = 9(4)\\ x= 36[/tex]

Answer:

{41 , 42 , 43 , 44 , 45}

Answer:

Set (x) = {41, 42, 43, 44, 45}

Step-by-step explanation:

Given statement,

→ A set of integers each is greater than 40 and less than 46.

Now the set will be,

→ 40 < x < 46

Then the members of the set are,

→ 40 < x < 46

→ 40 < 41 < 46

→ 40 < 42 < 46

→ 40 < 43 < 46

→ 40 < 44 < 46

→ 40 < 45 < 46

The list of required integers are,

→ 41, 42, 43, 44, 45

→ {41, 42, 43, 44, 45}

Hence, this is the correct answer.

Answer:

1) 130 degrees and 50 degrees 6) a price of a chair is 40, a price of the table is 80 7) a) 16 b)28

Step-by-step explanation:

1) Let it be that the first angle is x, The second one is y

1/5(x+y)=36- the first equation

1/2(x-y)=40- the second equation

The equations are simultaneous

x+y=180   and x-y=80

x+y+x-y=180+80

2x=260

x=130

y=50

6) The cost of a chair is x, the cost of table is y

6x+3y=480  2x+y=160

8x+y=400

8x+y- (2x+y)=400-160

6x=240

x=40

2*40+y=160

y=80

7) The Wan's age is x, the mother's age is y

x+y=60 x=60-y

Two years ago mother's age was y-2, when Wan;s age was x-2

y-2=(x-2)*3

y-2= (60-y-2)*3

y-2= (58-y)*3

y-2=174-3y

4y=176

y= 44

x=60-44=16- Wan's age now

44-16=28- her mother's age when she was born

Answer:

The paper is not clear :(

Step-by-step explanation:

Part A

Like with any other rectangle, we multiply the length and width to get the area

This applies even when we have algebraic expressions like this (recall that x is simply a placeholder for a number).

So,

area = length*width

area = (4x+5)*(3x+10)

area = w(3x+10) ..... replace (4x+5) with the variable w

area = 3xw + 10w ..... distribute

area = 3x(4x+5)+10(4x+5) .... plug in w = 4x+5

area = 3x*4x+3x*5 + 10*4x+10*5 .... distribute again

area = 12x^2+15x + 40x+50

area = 12x^2+55x+50

Answer: 12x^2+55x+50

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

Part B

The degree of any single variable polynomial is the largest exponent. In this case, the largest exponent is 2. This 2nd degree polynomial is considered a quadratic. Because we have three terms, this quadratic polynomial is also a trinomial. So there are many ways to describe the result of part A. Possibly the quickest way to describe it is to say "quadratic trinomial" to say all that has been mentioned in this paragraph.

Answers:

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

Part C

The concept of closure is the idea of taking two objects of the same type, applying some operation to them, and getting an output object of the same type.

Admittedly that last paragraph is a bit vague so I'll go over a few examples.

A non-example would be dividing whole numbers. Something like 10/2 = 5 is a whole number but 10/3 = 3.33 is not. This shows that integers are not closed under division. We don't always get a whole number output.

With polynomials, multiplying any two of them will result in some other polynomial. It's basically using the two examples in the bullet points and building upon them. That's the short version of why polynomials are closed under multiplication.

For this particular problem, (4x+5), (3x+10), and 12x^2+55x+50 are all polynomials.  

-----------

In terms of notation,

polynomialA * polynomialB = polynomialC

This notation hopefully shows that multiplying any two polynomials leads to another polynomial.

Answer:

A. 6x – 6

B. 2x²–15 +28

Step-by-step explanation:

A.

Perimeter = (length +width)×2

=[ (2x-7) + (x+4)] ×2

= ( 3x – 3)×2

= 6x – 6

B.

Area = length ×width

= (2x-7)(x-4)

= 2x²-8x-7x+28

=2x²-15x+28

6.5 - 2.75= 3.75

8) v = -3

9) m = 4

Explanation:

8)

[First distribute the factored terms on the left side of the equation]

2(v + 4) + 3(4v + 5) = -19 →

2(v) + 2(4) + 3(4v) + 3(5) = -19 →

2v + 8 + 12v + 15 = -19 →

[Next, add the like terms together]

(2v + 12v) + (8 + 15) = -19 →

14v + 23 = -19 →

[Subtract 23 from both sides to isolate the constant term]

14v + 23 – 23 = -19 – 23 →

14v = -42 →

[Lastly, divide both sides by 14 in order to obtain the value of v from the coefficient of 14 in 14v]

14v / 14 = -42 / 14 →

v = -3

9)

[Start by distributing the factored term on the left side of the equation]

2(m – 1) = 10 – m →

2m – 2 = 10 – m →

[Next, add m to both sides in order to isolate the m term and remove -m from the right side of the equation]

2m – 2 + m = 10 – m + m →

3m – 2 = 10 →

[Add 2 to both sides to isolate the constant term and remove -2 on the left side of the equation]

3m – 2 + 2 = 10 + 2 →

3m = 12 →

[Finally, divide by 3 on both sides in order to reduce the coefficient of 3 in 3m to get m]

3m / 3 = 12 / 3 →

m = 4

Step-by-step explanation:

The value of the 20th term in this sequence will be 102

Since we are given f(n)=6n−18.

In this case, we have been given n to be 20. Therefore, f(n)=6n−18 will then be written as:

f(n)=6n−18

f(20) = 6(20) - 18

f(20) = 120 - 18

f(20) = 102

In conclusion, value of the 20th term in this sequence will be 102
