The time required to get a total amount of $5,900.00 with compounded interest on a principal of $5,000.00 at an interest rate of 5.75% per year 2.899 years
<h3>Compound Interest </h3>
Given Data
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 5.75/100
r = 0.0575 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(5,900.00/5,000.00) / ( 4 × [ln(1 + 0.0575/4)] )
t = ln(5,900.00/5,000.00) / ( 4 × [ln(1 + 0.014375)] )
t = 2.899 years

Answer:
The half-life of the substance is 19.47 years.
Step-by-step explanation:
The equation for the amount of substance remaining is given by the following equation:
![Q(t) = Q(0)e^{-rt]](https://tex.z-dn.net/?f=Q%28t%29%20%3D%20Q%280%29e%5E%7B-rt%5D)
In which Q(t) is the amount remaining after t years, Q(0) is the initial amount and r is the rate that this amount decreases.
A sample of a radioactive substance decayed to 96.5% of its original amount after a year.
This means that 
We use this to find r. So
![Q(t) = Q(0)e^{-rt]](https://tex.z-dn.net/?f=Q%28t%29%20%3D%20Q%280%29e%5E%7B-rt%5D)
![0.965Q(0) = Q(0)e^{-r]](https://tex.z-dn.net/?f=0.965Q%280%29%20%3D%20Q%280%29e%5E%7B-r%5D)




So

(a) What is the half-life of the substance?
This is t when Q(t) = 0.5Q(0). So

![0.5Q(0) = Q(0)e^{-0.0356t]}](https://tex.z-dn.net/?f=0.5Q%280%29%20%3D%20Q%280%29e%5E%7B-0.0356t%5D%7D)





The half-life of the substance is 19.47 years.
