Answer:
13.86
Step-by-step explanation:
formula for cont. compounding interest is
Amount = Principal * e^rt
in this case the principal is 5000, and the amount is 10000 (double). the rate is 5% or 0.05. and t is what we are solving for.
sub in to get:
10000 = 5000e^0.05t
2 = e^0.05t
now convert to log form.
ln 2 = 0.05t
ln 2 / 0.05 = t
punch that into your calculator and you get 13.86 years
Add 1.5 to both sides:

Divide both sides by 2:

Consider the arcsin of both sides:

Arcsin and sin simplify, because they are inverse of each other:

The answer is 1940 or 7:40 which is 5 hours earlier than when she started.
To get the answer you multiply 17 by 30 which is 510. Next you add 510 and 1430 which is 1940. To get to regular time and not military time, subtract 12 from 19 and there you go! Hope this helps!!:))))))
