Answer:
C. 6 seconds.............
<u>Given</u>:
The given expression is 
We need to determine the equivalent expression.
<u>Equivalent expression:</u>
Let us determine the equivalent expression.
The equivalent expression can be determined by simplifying the given expression.
Hence, let us apply the exponent rule to simplify the given expression.
Thus, applying the exponent rule,
, we get;

Rewriting the expression, we get;

Simplifying, we get;

Thus, the equivalent expression is 
Hence, Option C is the correct answer.
Answer:
Account C will give George at least a 4% annual yield.
Step-by-step explanation:
This problem can be solved by using simple maths formula given below
Year rate = (1+i)^n-1
where i = compounding rate and n = interval period
Now checking annual rate for each option using above formula
Account A)
Yr = 3.8% ( n= 12 and i= 3.75/12)
Account B)
Yr = 3.9 % ( n= 4 and i= 3.85/4)
Account C)
Yr = 4 % ( n= 365 and i= 3.95/365)
Answer: Day 4 and 15
Step-by-step explanation:
Set up system of equations:

Simplify:

Factor: Both factors must be positive as the days can only be natural numbers.

x=4,15
