Answer:
The population increase by people per year at rate of 2.4 %
Step-by-step explanation:
Given in the question as
The Population of city in 2004 was 22,700
The population of city in 2010 is 26,300
Let the rate of increase of people per year is R%
So, population is increase from 2004 to 2010 i.e in 6 years
So, equation can be written as
Final population = Initial population ![( 1+ \frac{Rate}{100})^{6}](https://tex.z-dn.net/?f=%28%201%2B%20%5Cfrac%7BRate%7D%7B100%7D%29%5E%7B6%7D)
Or, 26,300 = 22,700 ![( 1+ \frac{Rate}{100})^{6}](https://tex.z-dn.net/?f=%28%201%2B%20%5Cfrac%7BRate%7D%7B100%7D%29%5E%7B6%7D)
Or,
= ![( 1+ \frac{Rate}{100})^{6}](https://tex.z-dn.net/?f=%28%201%2B%20%5Cfrac%7BRate%7D%7B100%7D%29%5E%7B6%7D)
Or, 1.158 = ![( 1+ \frac{Rate}{100})^{6}](https://tex.z-dn.net/?f=%28%201%2B%20%5Cfrac%7BRate%7D%7B100%7D%29%5E%7B6%7D)
Or ,
= 1 + ![\frac{Rate}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BRate%7D%7B100%7D)
Or , 1.024 - 1 = ![\frac{Rate}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BRate%7D%7B100%7D)
Or, 0.024 = ![\frac{Rate}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BRate%7D%7B100%7D)
∴ Rate = 0.024 × 100 = 2.4
Hence the population increase by people per year at the rate of 2.4% Answer
Answer:
The area of this triangle would be 24.
Step-by-step explanation:
In order to find this, we need to first determine what to use as the base of the triangle. Since when we draw it, the line between G and H is a flat line, it is the easiest to use as a base. Finding the length of the base is easy because we are simply looking for the difference in the x values.
6 - -2 = 8 = base
Now that we have the base, we need to find the height. The height is always the perpendicular line from the 3rd point to the base line. In this case, this would just be the change in y from the other two.
5 - -1 = 6 = height
Now that we have those two distances, we can just use the triangle formula.
A = 1/2bh
A = 1/2(8)(6)
A = 24
