Answer:
8,640
Step-by-step explanation:
14 because the decimal place has to be greater than 5. If it's above you round up, below you round down.
Hypotenuse therom ( a^2 + b^2 = c^2)
1) find c^2
22^2 + 16.1^2= c^2 ———->743.21
2) square root c^2 to find c
square root of 743.21 = 27.2 so D

Answer:
Approximately 22.97 years
Step-by-step explanation:
Use the equation for continuously compounded interest, which uses the exponential base "e":

Where P is the principal (initial amount of the deposit - unknown in our case)
A is the accrued value (value accumulated after interest is compounded), in our case it is not a given value but we know that it triples the original deposit (principal) so we write it as: 3 P (three times the principal)
k is the interest rate : 5% which translates into 0.05
and t is the time in the savings account to triple its value (what we need to find)
The formula becomes:

To solve for "t" we divide both sides of the equation by P (notice it cancels P everywhere), and then to solve for the exponent "t" we use the natural logarithm function:
