Answer:
Step-by-step explanation:
area of a circle=πr^2
42=3.14*r^2
42/3.14=r^2
13.37=r^2
=r
3.65=r
3.7=r
therefore radius of a circle is 3.7 ft
Question (a):
For this case we have the following function:
We must find the rate of change in the number of Internet users.
For this, we use the following equation:
- <em>For </em><em> we have:
</em>
- <em>For</em> <em>we have:
</em>
Substituting values we have:
Answer:
he rate of change in the number of Internet users in Mexico between 2004 and 2008 is:
Question (b):
- <em>For the year 2004 we have:
</em>
- <em>For the year 2008 we have:
</em>
Therefore, the percentage change is:
Substituting values:
Answer:
the percentage change in the number of Internet users in Mexico between 2004 and 2008 is:
Question (c):
For this case we have that the total population in Mexico for 2008, is given by:
109,955,400
The number of internet users for 2008 is:
15,030,000
Therefore, the percentage of the population that uses the internet in Mexico for 2008 is given by:
Substituting values we have:
Answer:
The Mexican population used the Internet in 2008 is:
Using the Pythagorean theorem, the height of the television is approximately 16 inches.
<h3>How to Apply the Pythagorean Theorem?</h3>
Given the following:
Length of the diagonal of the television = 27 inches
Width of the television = 22 inches.
Height of the television = ?
Using the Pythagorean theorem, we would find the height of the television as shown below:
Height of the television = √(27² - 22²)
Height of the television = √(729 - 484)
Height of the television = √245
Height of the television ≈ 16 inches
Thus, using the Pythagorean theorem, the height of the television is approximately 16 inches.
