By definition, we have:

In mathematics, a natural number is any of the numbers that are used to count the elements of certain sets, as well as in elementary calculation operations. They are those natural numbers that serve to count elements so they are whole.

For example:

1,2,3,4,5,6,7,8,9 ... ∞

By conventional definition it will be said that any member of the next set, ℕ = {1, 2, 3, 4, ...}, is a natural number.

Integers, whole numbers, real numbers, include natural numbers.

Answer:

Natural numbers are part of every other category of number except:

B. irrational numbers.

"Natural numbers" are the counting numbers ... one, two, three, seventy-two, etc.

They're the first group of numbers that children learn, and may well be the
most rational group of numbers you'll ever see.  One thing none of them is
is an irrational number.

           'B'.

A 40-m-long chain hangs vertically from a cylinder attached to a winch. Assume there is no friction in the system and the chain
daser333 [38]

Answer:

a) W₁ = 78400 [J]

b)Wt = 82320 [J]  

Step-by-step explanation:

a) W = ∫ f*dl      general expression for work

If we have a chain with density of 10 Kg/m, distributed weight would be

9.8 m/s² * 10 kg   = mg

Total length of th chain is 40 m, and the function of y at any time is

f(y) = (40 - y ) mg   where ( 40 - y ) is te length of chain to be winded

At the beggining we have to wind 40 meters   y = 0 at the end of the proccess  y = 40 and there is nothing to wind then:

f(y) = mg* (40 - y )

W₁ =  ∫f(y) * dy    ⇒ W₁ = ∫₀⁴⁰ mg* (40 - y ) dy  ⇒ W₁ = mg [ ∫₀⁴⁰ 40dy - ∫₀⁴⁰ ydy

W₁ = mg [ 40*y |₀⁴⁰   -  1/2 * y²  |₀⁴⁰    ⇒  W₁ = mg* [ 40*40 - 1/2 (40)² ]

W₁ = mg * [1/2]     W₁ = 10*9,8* ( 800 )

W₁ = 78400 [J]

b) Now we can calculate work to do if we have a 25 block and the chain is weightless

W₂ = ∫ mg* dy     ⇒    W₂  = ∫₀⁴⁰ mg*dy   ⇒    W₂  = mg y |₀⁴⁰

W₂ = mg* 40   = 10*9.8* 40  

W₂ = 3920 [J]

Total work

Wt = W₁  +  W₂        ⇒    Wt = 78400 + 3920

Wt = 82320 [J]

The answer to this, i don’t understand it
Akimi4 [234]
Answer:
9.2

Step-by-step explanation:
Since it is a right triangle, you can use the Pythagorean theorem to find the third side which is the hypotenuse.

a^2 + b^2 = c^2
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
9.219 = C
So, the answer rounded to the nearest tenth would be: 9.2

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 376 people entered the park, a
tatiyna

Answer:180 adults were admitted.

Step-by-step explanation:

Let x represent the number of children that were admitted into the park.

Let y represent the number of adults that were admitted into the park.

The admission fee at the amusement park is $1.50 for children and $4 for adults.

The admission fees collected totaled 1,014.00 dollars. This means that

1.5x + 4y = 1014 - - - - - - - - - -1

On a certain day, 376 people entered the park. This means that

x + y = 376

Substituting x = 376 - y into equation 1, it becomes

1.5(376 - y) + 4y = 1014

564 - 1.5y + 4y = 1014

- 1.5y + 4y = 1014 - 564

2.5y = 450

y = 450/2.5 = 180

Substituting y = 180 into x = 376 - y, it becomes

x = 376 - 180 = 196

Please please help me out!!!!!!!!!
anyanavicka [17]

Answer:

y = \frac{3}{4} x + \frac{1}{4}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (5, 4) ← 2 points on the line

m = \frac{4+2}{5+3} = \frac{6}{8} = \frac{3}{4}, thus

y = \frac{3}{4} x + c ← is the partial equation of the line

To find c substitute either of the 2 points into the partial equation

Using (5, 4), then

4 = \frac{15}{4} + c ⇒ c = 4 - \frac{15}{4} = \frac{1}{4}

y = \frac{3}{4} x + \frac{1}{4} ← equation of line
