Initially 100 milligrams of a radioactive substance was present. After 8 hours the mass had decreased by 4%. If the rate of decay is proportional to the amount of the substance present at time t, determine the half-life of the radioactive substance. (Round your answer to one decimal place.) hr
The quantity of a radioactive substance follows the law of uninhibited decay. If 126 grams are present to start and if 65 grams are present after 15 minutes, approximately how many grams will be present after 30 minutes? grams Round your answer to 2 decimal places as needed.
The population of an endangered species decreases at a rate of 7% per year. Approximately how long will it take the population to decrease to half of its current size?
A certain amount of an indissoluble substance containing 2 kg of salt in its pores is subjected to the action of 30 liters of water. After 5 min, 1 kg of salt dissolves. Within how long will 99% of the initial amount of salt dissolve? The rate of dissolution is proportional to the amount of salt that does not dissolve and to the difference between the concentration at the given instant and the concentration and the concentration of the saturated solution (1 kg for 3 litres). Give the result in minutes. The Answer should be: 10.47

Vivian takes a 425 mg aspirin for her headache. The amount of aspirin remaining in her system decays exponentially according to the model A=425⋅(0.855)tA=425⋅(0.855)t, Where AA is in milligrams (mg) and tt is in hours after she takes the aspirin. Answer the following questions, rounding each to the nearest whole mg. (a) How much aspirin is in Vivian's system immediately after taking the aspirin? (b) How much aspirin is in her system after 3 hours? (c) How much aspirin is in her system if she takes another aspirin 4 hours after the first?
