  1. If dp/dt = e^1/2t −100, then integrating gives p(t) = (1/2) * e^1/2t - 100t + C. Now, with the initial condition p(0) = 1000, you can find C. Done! Don't forget to vote best answer ! Hopefully no one will spoil you the answer. That...

  2. dN/dt = -No*e^(-t). When No = 0.40*5,000,000 = 2,000,000, then at t = 1 you have -dN/dt = 2000000/e, which is much more than 270671.  So I guess what is meant by "t years beyond 1990" is t years beyond the...

  7. 1,    y= a(1/2)^(t/t_half_life)      is half life formula      y = 0.9a   0.9a = a  (1/2)^(10/t_half_life)   0.9 = (1/2)^(10/t_half_life)        take ln of both sides  ln(0.9) =  (10/t_half_life)ln(1/2)  ln(0.9) /ln(1/2)  =  10/t_half_life    t_half_life =    10* ln(1/2) / ln(0.9)  =  65.78813479  Years  2...

  8. P(t)=262,576e^0.25t 1,000,000 = 262,576e^0.25t Taking natural logarithms of both sides gives: ln(1,000,000) = ln(262,576e^0.25t) ln(1,000,000) = ln(262,576) + ln(e^0.25t) ln(1,000,000) = ln(262,576) + 0.25t t = [ln(1,000,000) - ln(262,576)] / 0.25 t =5.35 years
