Final answer:
The question is related to exponential decay of a drug taken in 50 mg doses daily. The provided options represent different decay rates over time t (measured in hours). To determine the remaining amount of the drug after time t, multiply the initial dose by the corresponding option value.
Step-by-step explanation:
The question is related to the topic of exponential decay. It seems that the student is given options with different values of t (measured in hours) multiplied by 1.13e-6, 1.32e-6, 1.59e-6, and 1.82e-6. These options represent the decay of the drug over time. To determine the amount of the drug remaining after time t, you need to multiply the initial dose (50 mg) by the corresponding option value. For example, if the student chooses option b) 1.32e-6t, the amount remaining after time t would be 50 mg * 1.32e-6t.
