This problem is about componded interest. The formula for compounded interest is:

In this case, Initial = 300, r = 0.06 and t=10 so the total amount in the account after 10 years is:

The amount after 10 years is 573.26.
 
        
             
        
        
        
Area=pi (radius^2) Plug in numbers.
206=3.14 (r^2) Divide both sides by 3.14
65.61=r^2 Then square root both sides.
8.1ft =r Then round to the nearest foot.
r=8ft
        
             
        
        
        
The answer is B hope it helped
        
             
        
        
        
Answer:

Step-by-step explanation:
The PDF of X is
 
The PDF of Y is
 
The means of X and Y are respectively,
 
so we can see that the larger the parameter, the smaller the mean. Hence the PDF of Z = min(X, Y) is an exponential with the largest parameter of the two.
Therefore, the PDF of Z is
