and
#Since the population is reducing, can is obtained as
#The term is obtained using the formula
, given a=1200
The number of ants alive after every month (in first 4 months)
The ant's alive after 4 months is obtained as the value of
Hence, 936 ants are alive after 4 months.
b. As with the above question, the kitten population follows a geometric sequence: .
#Since it's a growing population , the common ration is the sum of 100% + the growth rate,
and
and
The population after 4weeks will be:
The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901
The amount of money gained after an investment is compounded is given by:
Where P is principal, A is the final amount, r is the rate, n is the number of times compounded per period and t is the time
Given that P = $1689, t = 4, r = 3% = 0.03, n = 1, hence:
The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901
