Answer:
Our expression is 205+2d where d is days past 60.
Step-by-step explanation:
Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.
205
Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:
205+2
Day 62 will be:
205 +2+2
Notice, that for two days past 60, the sunflower has grown 2 times as much.
Our expression is 205+2d where d is days past 60.

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
