Write a recursive and explicit formula for each option.
Save a nickel on the first day of the month and then double the amount each day for a month
=> a1 =0.05
=> a2 = a1* 2 = 0.05*2 
=> a3 = a2*2 = a1* 2*2
..............................................
=>recursive an =  
 
=> explicit an = 0.05* 
 
Start their savings by saving  $10  on the first day and then  $10  each day of the month
=> a1 = 10 
=> a2 = a1 + 10 = 20
=> a3 = a2 +10 = 20 +10 =30 
........................................................
=> recursive an = 
=> explicit an = 10 + 10( n-1) 
Hope it will find you well. 
 
        
             
        
        
        
Answer:
55.9%
Step-by-step explanation:
To find the percent that are girls, take the number of girls over the total number of students
19/34
.558823529
To change to percent form, multiply by 100%
55.8823529%
To 1 decimal place
55.9%
 
        
                    
             
        
        
        
In order for the product of some numbers to end in a zero, the prime factors of ... So 1 x 2 x 3 x ... x 98 x 99 x 100 (AKA 100!) has 24 zeroes at the end
