Answer: interest at the end of 3 years is $495.72
Step-by-step explanation:
The formula for simple interest is expressed as 
I = PRT/100
Where 
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 3 years
P = $3,672
R = 4.5%
Therefore
I = (3672 × 4.5 × 3)/100
I = 49572/100
I = 495.72
 
        
                    
             
        
        
        
Answer:
(0 ; 3)
Step-by-step explanation:
hello : 
the midpoint of the line segment is : ((-2+2)/2 ;(-2+8)/2 ) 
(0 ; 3)
 
        
                    
             
        
        
        
d = 3 , a₁₂ = 40 and S = 7775
 = 7775
In an arithmetic sequence the nth term and sum to n terms are
<h3>• a

 = a₁ + (n-1)d</h3><h3>• S

 = 

[2a + (n-1)d]</h3><h3>
where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ = 

[(2×7) +(99×3)</h3><h3>       = 25(14 + 297) = 25(311)= 7775</h3>
