Pesquisadores mediram a concentração de álcool no sangue (CAS) de oito homens adultos após o consumo rápido de $30 \mathrm{~mL}$ de etanol (correspondente a duas doses padrão de bebidas alcoólicas). A tabela mostra os dados que eles obtiveram ao tomar a média do CAS ( $\mathrm{em} \mathrm{mg} / \mathrm{mL}$ ) dos oito homens. (a) Use os valores para esboçar o gráfico do CAS como função de $t$. (b) Use seu gráfico para descrever como o efeito do álcool varia com o tempo. (TABLE CAN'T COPY)

Key Concepts

Pharmacokinetics (Concentration-Time Profile)

Pharmacokinetics is the study of how substances are absorbed, distributed, metabolized, and eliminated by the body. A concentration-time profile graph is used to illustrate how the level of a substance in the bloodstream changes over time, which is vital for understanding the onset, peak, and duration of its effects.

Trend Analysis in Time Series Data

Trend analysis involves examining data points collected or recorded at successive points in time to understand underlying patterns or changes. This includes identifying peaks, declines, and periods of stability, which can help explain how the behavior or effect of a measured variable evolves over time.

Independent and Dependent Variables

In any function or data set, the independent variable is the one that is manipulated or measured over time, while the dependent variable is the one that responds or changes based on the independent variable. Understanding which variable is independent (e.g., time) and which is dependent (e.g., blood alcohol concentration) is crucial for accurately representing and interpreting the data.

Graphical Representation of Data

This concept involves plotting numerical data on a coordinate system where one variable is represented on the horizontal axis and another on the vertical axis. It allows for visualizing relationships, trends, and patterns in the data, and aids in the interpretation of complex information by converting numerical values into a visual format.
