A radioactive substance decays at a rate proportional to the amount present at ime t (in hours). Initially, Ao grams of the substance was present, and after 10 hours, the mount has decreased by 20% How long will it take the substance to decay to 40? hat is the half life of this substance? Hint: the half-life is the time required for half of the initial substance to decay)

Part III continued 6. The rate of decay of a radioactive substance is proportional to the amount present. Today we have 10 grams of a radioactive substance. Given that 1/3 of the substance decays every 5 years, how much will be left 17 years from today? 7. Evaluate the following integrals: a) 5-4x-x2 dx, x2-x3

The radium in a peace of lead decomposes at a rate which is proportional to the amount present. if 10 percent of the radium decomposes in 200 years, what percent of the original amount of radium will be present in a piece of lead after 1000 years. the answer is 59.05%. I know how to find the answer. but I don't know how to find it using diffrential equation. PLEASE expalin every step and say why !

During a research experiment, it was found that the number of bacteria in a culture grew at a rate proportional to its size. At 6:00 AM there were 4,000 bacteria present in the culture. At noon, the number of bacteria grew to 4,800. How many bacteria will there be at midnight? There will be about bacteria at midnight. (Do not round until the final answer. Then round to the nearest whole number as needed.)
