Answer:
The answer is the option
Step-by-step explanation:
Let's verify all the cases to determine the solution to the problem.
case A) we have
The domain is the interval-------> (-∞,∞)
The domain is all real numbers
case B) we have
The domain is the interval-------> (-∞,∞)
The domain is all real numbers
case C) we have
we know that
the denominator can not be equal to zero
so
The domain is the interval-------> (-∞,0) ∩ (0,∞)
The domain is all real numbers except the number zero
case D) we have
The domain is the interval-------> (-∞,∞)
The domain is all real numbers

Answer:
The answer would be 20.97273616 or (rounded to the nearest cent) would be $20.97
Step-by-step explanation:
The reason for this is that the formula for compounded interest is where A is the total amount, P is the initial amount, r is the growth factor or the percent, n is the number of compounding periods, and t is the time. You would substitute P for 16, r for 0.14 (14%), n for 2 as it compounded semiannually so it for every 6 months instead of 1 year (annual) so is compounded 2 times per year, and t for 2. And just solve the equation and you get that A is equal to 20.97273616 but since we are talking about money( only round if asked) then it would be 20.97.
Hope this helps!!!!
