4. Given that an amount (in grams) of Radium -- 226 decays in such a way that after t years, the amount left is given by $A(t) = 500e^{-0.000436t}$. How much Radium remains after 2000 years?

Suppose that $d A / d t=-0.0004332 \mathrm{A}(t)$ represents a mathematical model for the decay of radium- 226 where $A(t)$ is the amount of radium (measured in grams) remaining at time $t > 0$ (measured in years). How much of the radium sample remains at the time when the sample is decaying at a rate of 0.002 grams per year?

Suppose that $$ A^{\prime}(t)=-0.0004332 A(t) $$ represents a mathematical model for the decay of radium 226 , where $A(t)$ is the amount of radium (measured in grams) remaining at time $t$ (measured in years). How much of the radium sample remains at time $t$ when the sample is decaying at a rate of $0.002$ grams per year?
Ordinary Differential Equations
The amount of radium 226 remaining in a sample that originally contained $A$ grams is approximately $$ C(t)=A(0.999567)^{t} $$ where $t$ is time in years. Find the half-life to the nearest 100 years. HINT [See Example 4a.]
