Answer:
the interest is $975
the total amount is $5975
Step-by-step explanation:
lets use tje formula
I=PRT
where I is interest earned
P is the principal amount(original amount)
R is the rate of interest
and T is the time in years
so
the principal amount is 5000 since it is the original amount
rate is =0.065
time is 3 years
lets plug these values into our equation:
5000*0.065*3=I
5000*0.065*3=975
the interest is $975
the next part of the question is asking for the balance or the total amount which is principal+interest
5000+975=5975
the total amount or balance is $5975
hope this helps
It would be 23 and 24! YOU'RE WELCOME :)
Answer:
Half life = 4.7 days
Step-by-step explanation:
Formula to get the final amount of the substance after the time 't',
Here, = Final amount of the substance
= Initial amount
k = decay constant
t = Duration or time
Now by substituting the values in the formula,
If [For half life]
ln(2) =
0.69315 = 0.1473t
t = 4.71 days
t ≈ 4.7 days
Therefore, half life of the substance is 4.7 days.
