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:

They're both acute

Step-by-step explanation:

They both meausre less than 90°

A right angle would look like an L (it could be a flip L as well)

And an obtuse angle is anything bigger than a right angle

The first 10 pounds is $2 per pound so $2 x 10 = $20

She wants to pick 40 pounds so after the first 10 pounds she needs 40-10 = 30 more pounds.

The cost for those are $1 per pound so 30 x $1 = $30

Total cost = $20 + $30 = $50 for 40 pounds.

Answer:

w = [tex]\frac{P-2h}{2}[/tex]

Step-by-step explanation:

Given

P = 2w + 2h ( subtract 2h from both sides )

P - 2h = 2w ( divide both sides by 2 )

[tex]\frac{P-2h}{2}[/tex] = w

Answer:

216m² is your answer

Step-by-step explanation:

given

width [b]=2/3 ×l

length [l]=l

height [h]=1/3 l

we have

volume of cuboid =l×b×h

1296m³=l×2/3×l×1/3×l

1296m³=2/9×l³

l³=1296×9/2=5832

l³=18³

length [l]=18m

breadth [b]=2/3×18=12m

area of base of box =l×b=18×12=216m²

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:

72 remainder 8 i think

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

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]

So, the area of a sector is equal to [tex]11.7\ m^2[/tex].
