Peter deposited $8,975 into a savings account 21 years ago. The account has an interest rate of 3.8% and the balance is currentl
Alexus [3.1K]
The formula for the future value of the account is
  A = P(1 + r/n)^(nt)
where you have
  A = 19909.20
  P = 8975
  r = 0.038
  t = 21

The resulting equation is not one that can be solved by algebraic means, but we can use a graphing calculator to find n. This graph shows us n = 12, so

the interest compounds monthly.

A certain radioactive isotope decays at a rate of 2% per 100 years. if t represents time in years and y represents the amount of
gregori [183]
We rewrite the equation:
 y = y0 * e ^ (- 0.0002 * t)
 In this equation:
 I = represents the initial amount of the isotope
 We have then:
 89% of the isotope left:
 0.89 * y0 = y0 * e ^ (- 0.0002 * t)
 We clear the time:
 e ^ (- 0.0002 * t) = 0.89
 Ln (e ^ (- 0.0002 * t)) = Ln (0.89)
 -0.0002 * t = Ln (0.89)
 t = Ln (0.89) / (- 0.0002)
 t = 582.6690813
 round to the nearest year:
 t = 583 years
 Answer:
 
There will be 89% of the isotope left in about:
 
t = 583 years
