Answer:

2562 - 960√5/11

Step-by-step explanation:

We are given here the value of x as 4 - √5. We need to find the value of x² + 1/x² . So let's find out 1/x

⇒ x = 4 - √5

⇒ 1/x = 1/4-√5

⇒ 1/x = (4 + √5) / ( 4 - √5) ( 4 + √5 )

⇒ 1/x = 4 + √5 / 4² - (√5)²

⇒ 1/x = 4+√5 / 16 - 5

⇒ 1/x = 4+√5/11

⇒ x² + 1/x² = (4-√5)² + (4+√5)²/11²

⇒ x² + 1/x² = 121( 16 + 5 -8√5 ) + 16 + 5 + 8√5 / 121

⇒ x² + 1/x² = 1936 + 605 - 968√5 + 21 + 8√5 / 121

⇒ x² + 1/x² = 2562 - 960√5/11

Answer:

W' = 54.4  pounds

Step-by-step explanation:

Given that,

The weight of a bag of books = 40 pounds

After picking up some books at school, the weight has increased by  36%.

We need to find the weight of the bag now. Let the new weight is W'.

So,

W' = 40 +36% of 40

i.e.

[tex]W'=40+\dfrac{36}{100}\times 40\\W'=54.4\ pounds[/tex]

So, the new weight of the bag is equal to 54.4  pounds.

Answer:

C.

yes; y = 1.8x

Step-by-step explanation:

Answer for the question :

Yes, Y varies directly with X, and the equation is :

Y = 1.8X

NOTE : For every value of X, when you multiply them with 1.8, you will get the corresponding Y.  

Y = 1.8 x X

5.4 = 1.8 x 3

12.6 = 1.8 x 7

21.6 = 1.8 x 12   (Q.E.D.)

That’s the answer, good luck in solving the question!

:-)

ideal all you ought to do is to divide the y via potential of x and u get the equation working occasion #a million y=32 / x=4 then u have y/x=32/4 ----> y=8x and do the comparable indoors something so #2 y=-20 & x=-20 so y/x=-20/-20 y=x etc

The linear equation is given as y = 1.8x, Then the correct option is C.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

The table is given below.

x         y

3      5.4

7      12.6

12     21.6

Then the linear equation is given as,

[tex]\rm (y - 5.4) = \left [\dfrac{5.4-12.6}{7-3} \right] (x-3)[/tex]

Simplify the equation, then we have

y - 5.4 = 1.8(x - 3)

y - 5.4 = 1.8x - 5.4

y = 1.8x

The linear equation is given as y = 1.8x, Then the correct option is C.

Answer:

[tex]A=11.7\ m^2[/tex]

Step-by-step explanation:

Given that,

Central angle, [tex]\theta=160^{\circ}[/tex]

Diameter,d = 5.8 m

Radius, r = 2.9 m

We need to find the area of sector. The formula for the area of sector is given by :

[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{160}{360}\times 3.14\times 2.9^2\\\\=11.7\ m^2[/tex]

Step-by-step explanation:

The result of dividing 1675 by 25 is 67 with a remainder of 0.

Given that we need to divide 1675 by 25,

To divide 1675 by 25 with a remainder, we can use long division.

Here's how it works:

Step 1: Write the division problem in long division format:

-----------

25 | 1675

Step 2: Start with the first digit of the dividend (1675) and divide it by the divisor (25).

Write the quotient above the line and the remainder to the right of the line:

-----------

25 | 1675

67

Step 3: Multiply the quotient (67) by the divisor (25) and write the product below the dividend:

-----------

25 | 1675

- 1650

67

Step 4: Subtract the product from the dividend and bring down the next digit (in this case, the digit 5):

-----------

25 | 1675

- 1650

----

25

67

Step 5: Repeat the process by dividing the new dividend (25) by the divisor (25). The quotient will be 1, and there will be no remainder:

-----------

25 | 1675

- 1650

----

25

25

-----

0

Step 6: Since the remainder is 0, we have divided 1675 by 25 evenly.

Therefore, the result of dividing 1675 by 25 is 67 with a remainder of 0.

Answer:

The 75th term in the sequence is 16

Step-by-step explanation:

The 75th term of a sequence can be considered as the term that is in the position at 75% along the sequence. This is assuming that the sequence has been sorted already from lowest value to highest value

In this sequence, which has 4 terms, we can find the 75th term by finding what term is at 75% (or three-quarters) along the sequence.

To find the 75th term:

Multiply the number of terms by 0.75 (or 75%/100%) :

             0.75*4 terms= 3

Then, we find the value of the term that is at position 3 from the left (lowest number)

In this case, the term that is at the 3rd position from the left is 16

Thus, the 75th term in the sequence is 16
