A person invests 4000 dollars in a bank. The bank pays 5.75% interest compounded
OlgaM077 [116]

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

  • Principal P = $4000
  • Rate r= 5.75%
  • Final Amount A =  %5900

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

A sample of a radioactive substance decayed to 96.5% of its original amount after a year. (Round your answers to two decimal pla
jek_recluse [69]

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]

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 Q(1) = 0.965Q(0)

We use this to find r. So

Q(t) = Q(0)e^{-rt]

0.965Q(0) = Q(0)e^{-r]

e^{-r} = 0.965

\ln{e^{-r}} = \ln{0.965}

-r = =0.0356

r = 0.0356

So

Q(t) = Q(0)e^{-0.0356t}

(a) What is the half-life of the substance?

This is t when Q(t) = 0.5Q(0). So

Q(t) = Q(0)e^{-0.0356t}

0.5Q(0) = Q(0)e^{-0.0356t]}

e^{-0.0356t} = 0.5

\ln{e^{-0.0356t}} = \ln{0.5}

-0.0356t = \ln{0.5}

t = -\frac{\ln{0.05}}{0.0356}

t = 19.47

The half-life of the substance is 19.47 years.
