A) Now look, in the year 2000, the population is 118,000
In the year 2006 is 138,000
To find the percent change |Original Amt - New Amt|                                            --------------------------------       x100
                                                 Original Amt
So for this question you would do 118,00 - 138,000 (ignore the negativesss)
     and you get -20,000 (ignore the negatives) and then you get 20,000
Now, you have to do 20,000 divided by 118,000 x 100
20,000 divided by 118,000 and you get 0.169491525 
Now you have to multiply 0.169491525 by 100
0.169491525 x 100 = 16.9491525 
Round this and you get a 16.9% change. 
b) To predict the population in 2012 you will have to do 138,000 + 16.9% 
To calculate this you have to do this: 
                                                 138,000 x 0.169 = 23322 
Now add 23,322, to 138,000 and you get 161,322.
A) 16.9%
B) 161,322 
hope this helped :)
        
             
        
        
        
Answer:
It's not specific enough, I'll come back to you!
 
        
             
        
        
        
26^2 = 18.8^2 + H^2
H^2 = 322.56
H = 17.96 inches
