Answer:
Step-by-step explanation:
d=20t+1/3, b=30t
20t+1/3=30t
10t=1/3
t=1/30 hr
t=(1/30)60=2 min
We are given that,
The fall of the acorn is represented by the function,
Equating S(t) to 0 gives,
i.e.
Since, time cannot be negative.
So, i.e. 1.25 seconds is the time when the acorn will reach the ground.
Thus, from the figure below, we see that,
The interval in which the acorn is in the moving air is .
Math isnt my strongest subjuect but i believe it it right.
173.80 interest, 4518.80 total
4345 X .03(3%)=130.35/year
130.35/12=10.8625/month
10.8625 x 16 months = 173.80 interest over 16 months
4345+173.80=4518.80 total amount
