First you want to get h alone so you divide 2<span>π</span>r by s so your answer would be 
h=S/2πr
        
                    
             
        
        
        
Answer: Δx = 0.5
Step-by-step explanation:
We have the interval:
 [−3, −1]
and we partition it into 4 equal intervals.
first, the range of our interval is equal to the difference between the extremes, this is:
-1 - (-3) = -1 + 3 = 2
Then, if we divide it into 4, we have 4 segments with a range of:
2/4 = 0.5
Then the subinterval delta is 0.5, and the 4 intervals are:
 [−3, -2.5],  [−2.5, −2],  [−2, −1.5],  [−1.5, −1]
 
        
             
        
        
        
X = y - 5 
x = 1 - y / 3
I hope this helps. :)
        
                    
             
        
        
        
7^6/7^2
(7*7*7*7*7*7)/(7*7)
the answer is b. 7^4
