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
Answer:
5 inches
Step-by-step explanation:
A cone's volume can be found using the formula
. If the cone has a diameter of 3 inches then its radius is half r= 1.5 inches. Substitute r = 1.5 and V = 12 cubic inches.

This means the height of the cone is 5.10 inches or to the nearest inch 5 inches.
Turn percentage into a fraction.
15% = 0.15
Divide.
60 / 0.15 = 400
Hence, 15% of 60 is 400.
Hope This Helped! Good Luck!
