Solution Summary: The author calculates the period of time needed for initial investment to double, if an interest rate of 3.5% is secured.
a. The time
t
(in years) required for an investment to double with interest compounded continuously depends on the interest rate
r
according to the function
t
r
=
ln
2
r
.
b. If an interest rate of
3.5
%
is secured, determine the length of time needed for an initial investment to double. Round to 1 decimal place.
8. For x>_1, the continuous function g is decreasing and positive. A portion of the graph of g is shown above. For n>_1, the nth term of the series summation from n=1 to infinity a_n is defined by a_n=g(n). If intergral 1 to infinity g(x)dx converges to 8, which of the following could be true? A) summation n=1 to infinity a_n = 6. B) summation n=1 to infinity a_n =8. C) summation n=1 to infinity a_n = 10. D) summation n=1 to infinity a_n diverges.
