For this case we have:
By properties of the radicals 
So:
 .
.
Now, for power properties we have:

Thus, 
So:

7 is the answer, you have to divide 475 by 78 and you get 6.08974358974359 but you round it up to 7 to make sure you have enough buses
        
             
        
        
        
Answer:
3.14 million
Step-by-step explanation:
10.676 - 7.536 = 3.14
To check 
7.536 + 3.14 = 10.676
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Given that there is a function of x,

Let us find first and second derivative for f(x)

When f'(x) =0 we have tanx = 1 and hence 
a) f'(x) >0 for I and III quadrant 
Hence increasing in 
and decreasing in 


Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1

are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)
 
        
             
        
        
        
You do 18.99$ + 2.85$.  ( 2.85$ is 15% of 18.99 )
