Answer:

<h2>What are natural numbers?</h2>

<u>the positive integers or whole numbers include 1, 2, 3, and etc. sometimes zero.</u>

<h2>What are whole numbers?</h2>

<u>Whole numbers are 0, 1, 2, 3, 4, 5, 6</u>. Whole numbers include positive integers along with 0.

17, 99, 267, 8107 and 999999999 are examples of whole numbers.

<h2>What are rational numbers?</h2>

<u>A rational number is a number that can be express as the ratio of two integers.</u> A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333

<h2>What are irrational numbers?</h2>

<u>A real number that can NOT be made by dividing two integers </u>(an integer has no fractional part). "Irrational" means "no ratio", so it isn't a rational number.

Example: π is an irrational number.

<h2>What are real numbers?</h2>

<u>The real numbers include all the rational numbers,</u> such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as √2.

Included within the irrationals are the transcendental numbers, such as π

Find a polynomial for the sum of the shaded<br> areas of the figure. A = 6, B = 4

soldi70 [24.7K]

Answer:

The polynomial for the sum of the shaded $\pi$ r² - 20 $\pi$

Step-by-step explanation:

Given as :

The figure is shown which is of concentric circle with radius B , A , r

The radius B = 4 unit

The radius A = 6 unit

Let The sum of shaded portion = x unit

Now, The circumference of circle = 2 $\pi$ R , where R is the radius

So, for circle with radius B.

The circumference = 2 $\pi$ R = 2 $\pi$ B

Or, The circumference = 2 $\pi$ × 4 = 8 $\pi$

<u>Similarly</u>

For circle with radius A.

The circumference = 2 $\pi$ R = 2 $\pi$ A

Or, The circumference = 2 $\pi$ × 6 = 12 $\pi$

Now, <u>The area of circle with radius r is</u>

Area = $\pi$ ×radius × radius

Or, Area = $\pi$ r²

Now,

The sum of shaded region area = The area of circle with radius r - ( The circumference with radius B + The circumference with radius A )

Or, The sum of shaded region area = $\pi$ r² - ( 8 $\pi$ + 12 $\pi$ )

Or, The sum of shaded region area = $\pi$ r² - 20 $\pi$

Hence The polynomial for the sum of the shaded area is $\pi$ r² - 20 $\pi$ Answer

Which statement is true for the vertical number line? A. -2.5 is located below -3.5 . B. -4.8 is located below 4.8 . C. 3.25 is

meriva

Answer:

B. -4.8 is located below 4.8 . TRUE

Step-by-step explanation:

The vertical line is called the Y - AXIS.

Here also, the integers are expressed as same as the horizontal axis.

.... -5, -4, -3, -2, -1 , 0 , 1 2,3 4,5 ....

In vertical line, If we move above 0, the value INCREASES.

If we move Below 0, the value DECREASES.

Now, consider the given cases:

A. -2.5 is located below -3.5 .

Here, as -3 lies Below -2.

So, -2 > -3 ⇒ -2.5 > -3.5

So, -2.5 is located ABOVE 3.5.

B. -4.8 is located below 4.8 .

Here, as -4 lies Below 4.

So, 4 > -4 ⇒ 4.8 > -4.8

So, -4.8 is located BELOW 4.8.

C. 3.25 is located above 3.75 .

Here, 3.75 > 3.25

⇒ 3.75 is located ABOVE 3.25.

D. -0.5 is located below -1.5 .

Here, as -1.5 lies Below 0.5.

So, -0.5 > -1.5

⇒ -0.5 is located ABOVE -1.5.

E. 0 is located below -0.87 .

Here, as -0.87 lies Below 0.

So,0 > -0.87

⇒ 0 is located ABOVE-0.87.

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximatel

Murrr4er [49]

Answer:

The monument is approximately 86.6 feet tall

Step-by-step explanation:

The given monument parameters are;

The distance of the person from the monument = 50 feet

The angle of depression from the top of the monument to the person's feet = 64°

Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;

tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)

∴ The height of the monument = tan(Angle of depression) × The distance from the monument

Substituting the known values, gives;

The height of the monument = tan(60°) × 50 ≈ 86.6

The height of the monument ≈ 86.6 feet.
