For domain 2x sqrt(2+x)>0
x>0,2+x>0,x>-2 combining 
we get x>2
f'(x)=[1/{2x sqrt(2+x)}][{2x/(2 sqrt(2+x))}+2 sqrt(2+x)]
        
             
        
        
        
Answer:
   x = 2.5 or 7.5
Step-by-step explanation:
Subtract 3/4.
   |5 -x| = 10/4 = 2.5
This resolves to two equations:
- 5 -x = 2.5   ⇒   x = 5 -2.5 = 2.5
- 5 -x = -2.5   ⇒   x = 5 +2.5 = 7.5
The solutions are x = 2.5 or 7.5.
 
        
             
        
        
        
If all 4 projects take 15 days, then you multiply 15 times 4. Since 15 * 4 = 60, you will have 60 days to complete the 4 projects.
        
             
        
        
        
If a certain place's population is given to be growing at a rate of 4.8% annually, the population after t years from 2003 will become (1.048^t) times the given initial population. This translates to a mathematical equation which is equal to,
                                At = (584,658(1.048^t)
