Question

At the beginning of an experiment, a scientist has 128 grams of radioactive goo. After 255 minutes, her sample has decayed to 2 grams. What is the half-life of the goo in minutes? Find a formula for G(t), the amount of goo remaining at time t. G(t) = How many grams of goo will remain after 74 minutes?

Step 1

Given: Initial amount, G(0) = 128 g Amount after 255 minutes, G(255) = 2 g Using the formula for exponential decay: G(t) = G(0) * 2^(-t/half-life), where t is the time elapsed and half-life is the time taken for the amount to halve. Plugging in the values: 2 = Show more…
