Answer:
   c)  0.0156
Step-by-step explanation:
The general term a[n] of a geometric sequence is given in terms of the first term a[1] and common ratio r as ...
   a[n] = a[1]r^(n-1)
The given sequence has an initial term of a[1]=8 and a common ratio of 4/8=1/2. Then the general term is ...
   a[n] = 8(1/2)^(n-1)
The 10th term is then ...
   a[10] = 8(1/2)^(10-1) = 8(1/2)^9 = 8/512
   a[10] = 0.015625 ≈ 0.0156
 
        
             
        
        
        
Answer:
Step-by-step explanation:
X + X + 96 = 180    {SUM OF ANGLES OF TRIANGLE}
2X + 96 = 180
2X = 180 -96
2X =84
X = 84/2
X = 42
 
        
                    
             
        
        
        
It was reduced because as you can see on the scale the actual picture has larger spaces between the numbers.
        
             
        
        
        
The circumference of circle with a radius of 63mm is 395.84
