Natural numbers are a part of the number system which includes all the positive integers from 1 till infinity and are also used for counting purpose. It does not include zero. In fact, 1,2,3,4,5,6,7,8,9…., are also called counting numbers excluding zero, fractions, decimals and negative numbers.
The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.
Natural numbers are also all numbers 1, 2, 3,4.. and so on. They are the numbers you usually count and they will continue on into infinity. Whole numbers are all natural numbers including 0. 0, 1, 2, 3, 4… Integers include all whole numbers and their negative counterpart, -4, -3, -2, -1, 0,1, 2, 3, 4,…
So in all these words, this means that natural numbers are all the numbers not including 0 and negative and whole numbers are all the numbers including 0 and negative.

A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 70 square feet. Find the length of the rectangle.
Answer:
The length of the rectangle (l) = 10 cm
The width of the rectangle (w) = 7 cm
Step-by-step explanation:
Step(i):-
Let 'x' be the length of the rectangle
Given that the width is 3 feet shorter than the length
The width of the rectangle = x -3
Area of the rectangle = length × width
Step(ii):-
Area of the rectangle = length × width
= x ( x-3)
Given that the area of the rectangle = 70 square feet
x ( x-3) = 70
⇒ x² - 3x - 70 =0
⇒ x² - 10 x + 7 x - 70 =0
⇒ x (x -10) +7( x-10) =0
⇒ ( x+7) ( x-10) = 0
⇒ x =-7 and x=10
Final answer:-
we choose x=10
The length of the rectangle (l) = 10 cm
The width of the rectangle (w) = 7 cm

In ΔDEF, d = 36 inches, e = 97 inches and ∠F=166°. Find the length of f, to the nearest inch.
Answer is 11.9ft.
Law of cosines:
In trigonometry, the Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.
[tex]c^{2} = a^{2} + b^{2} - 2ab cos(C)[/tex]
Since we have two side lengths and an angle, we can use the Law of Cosines to find the length of the final side.
In this case we can write the law of cosines as,
[tex]f^{2} = d^{2} + e^{2} - 2(de)cos(F)[/tex]
f2 = 5.22 + 6.82 - 2(5.2)(6.8)cos(166)
f2 = 27.04 + 46.24 - 66.56 cos (166)
f2 = 73.28 - 66.56 cos 166
f = √(73.28 - 66.56 cos 166) ≈ 11.9 ft.
f ≈ 11.9 ft.

The total population of Aiken County is 173,000 and there are approximately 23,000 students enrolled in Aiken County schools. What percentage of Aiken County residents are enrolled in Aiken County schools? Round your answer to the nearest tenth.
Answer:
Percentage = 13%
Step-by-step explanation:
Given the following data;
Total population = 173,000
Number of students = 23,000
To find the percentage;
[tex] Percentage = \frac {Number \; of \; students}{Total \; population} * 100 [/tex]
[tex] Percentage = \frac {23,000}{173,000} * 100 [/tex]
[tex] Percentage = \frac {23}{173} * 100 [/tex]
[tex] Percentage = 0.1330 * 100 [/tex]
Percentage = 13.3 ≈ 13%
Therefore, the percentage of Aiken County residents that are enrolled in Aiken County schools is 13%.

The weights of 1000 onions from a certain farm follow a normal distribution with a mean of 150 g and a standard deviation 15 g from the data we can conclude that about blank onions way more than 165 g in about blank onions way less than 135 g
Answer:
About 159 weigh more than 165 g and about 159 g weigh less Than 135 g
Step-by-step explanation:
Given that :
Mean, μ = 150
Standard deviation, σ = 15
Using the Zscore formula :
Zscore = (x - μ) / σ
For x > 165
P(x > 165)
Z = (165 - 150) / 15
Z = 15 /15 = 1
P(Z > 1) = 0.15866 (Z probability calculator)
1000 * 0.15866 = 158.66 = 159
For x < 135
P(x < 135)
Z = (135 - 150) / 15
Z = - 15 /15 = - 1
P(Z > - 1) = 0.15866 (Z probability calculator)
1000 * 0.15866 = 158.66 = 159

Which graph represents the function f(x)=5lnx?
Answer:
The first graph (top-left) is the correct graph.
Please, also check the attached graph.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=5\:lnx[/tex]
First, we should determine the x and y-intercepts.
Determining the y-intercept:
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
Thus,
substitute x = 0 in the function
y = lnx
y = ln(0)
y = undefined
Therefore, at x = 0, the value of y becomes undefined.
Hence, None is the y-intercept.
Determining the x-intercept:
We know that the value of the x-intercept can be determined by setting y = 0 and determining the corresponding value of x.
Thus,
substitute y = 0 in the function
0 = ln(x)
Flipe the equation
ln(x) = 0
Solve algorithm
ln(x) = 0
Take exponent of both sides
[tex]\:e^{ln\left(x\right)}=e^0[/tex]
[tex]x\:=e^0[/tex]
[tex]x = 1[/tex]
Thus, the point of x-intercept is: (0, 1)
Conclusion:
Now, if we carefully check the graph options, we can easily figure out that the first graph (top-left) correctly displays the x and y-intercepts.
It is clear from the graph that:
at x = 0, y is heading towards -ve infinity.
at y = 0, x = 1
Therefore, the first graph (top-left) is the correct graph.
Please, also check the attached graph.
