Answer:
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a square, which is:
Where s is the lenght of a side of the square.
2. By definition, the sides of the square have equal lenghts. You can calculate the lenght of a side by calculating the distance between two vertices of the aquare:
Where is the lenght of the side AB.
3. The area is:
Answer:
The population in 2011 will be of 34.88 million people.
Step-by-step explanation:
The population after t years is modeled by an exponential function is the following format:
In which P(0) is the initial population and r is the growth rate.
At the beginning of 1990, 21.7 million people lived in the metropolitan area of a particular city.
This means that
The 1998 population was 26 million.
1998 is 8 years after 1990. So
We use this to find the value of r.
So
If this trend continues, how large will the population be in the year 2011?
2011 is 21 years after 1990. So this is P(21).
The population in 2011 will be of 34.88 million people.
Answer:
Vertical opposite angles are the same so the answer is D.
Answer: 7 / 2 or 3 1/2.
Just add the numerators because the denominators are the same.
