Answer:
31 years to triple the investment
Step-by-step explanation:
Initial investment = 300
Triple amount that is final amount = 300*3= 900
rate of interest = 3.5 % = 0.035
we need to find out number of years (t)
for compounded continuously we use formula

A is the final amount
P is the initial amount
r is the rate of interest
t is the number of years

Divide both sides by 300

take 'ln' on both sides

ln(3) = 0.035t ln(e)
ln(e)= 1

t= 31.3889
Round to nearest whole number
t= 31 years
15/3 + 4/3 = 19/3
All you have to do is subtract 4/3 from 19/3 to get 15/3
Common ratio, r is found by dividing the next term by the previous term
r =

= -3
you can see this value is true for any consecutive pairs of terms
also, multiply by -3 to get the next term

s_f=8/2=4
answer: 4
Answer: The answer is 8.
Step-by-step explanation:
<em>You subtract 3 from 7 and then and 5 so there that is your answer which is 8, thank me later < 3 ! :)</em>
