Answer:
enrollment decreases by 14.34%.
Step-by-step explanation:
Given that number of students enrolled in 2000 = 823
Given that number of students enrolled in 2010 = 705
705 is less than 823 so that means number of students enrollment is decreasing.
Decrease = 823-705 = 118
Percent decrease is given by formula:

which is approx 14.34%.
Hence final answer is that enrollment decreases by 14.34%
 
        
             
        
        
        
Answer:
StartFraction pi Over 3 EndFraction
Step-by-step explanation:
we know that
The circumference of a circle subtends a central angle of 360 degrees or 2π radians
so
by proportion
Find out the central angle for an arc equal to One-sixth of the circumference of a circle
Let
x -----> the measure of the central angle in radians for an arc equal to One-sixth of the circumference 

Simplify

therefore
StartFraction pi Over 3 EndFraction
 
        
                    
             
        
        
        
It's a Fibonacci sequence sum of two prior (Xn=Xn-1+Xn-2). X6=X6-1+X6-2
X6=X5+ X4 
So the answer is 59.

The reflection of the point (x,y) across the x-axis is the point (x,-y), so take the coordinates of each point and change them accordingly then graph them.
