Answer:
Capital value after 1 year will be equal to $45150
Step-by-step explanation:
We have given principal amount P = $42000
Rate of interest r = 7.5 %
Time t = 1 year 
Capital value is given by 
So 

So capital value after 1 year will be equal to $45150
 
        
             
        
        
        
Answer:
x = -4.604
Step-by-step explanation:
Here, we want to get the value of x 
We start by dividing through by 5
e^(2x + 11) = 30/5
e^(2x + 11) = 6 
Writing this in natural logarithm form, we have;
ln 6 = 2x + 11
2x + 11 = 1.792
2x = 1.792-11
2x = -9.208
x = -9.208/2
x = -4.604 
 
        
             
        
        
        
The length of the rectangle would be 94m.
        
             
        
        
        
Through my understanding of the question I think the correct answers would be A and D.
