You drink a beverage with 100 mg of caffeine. Each hour, the caffeine in your system decreases by about 20%. How long until you have about 41 mg of caffeine?

Caffeine has a half-life of about 5 hours.

Someone who consumes 40 milligrams (mg) of caffeine will have 20 mg remaining in their system after 5 hours.

When do effects peak?

Levels of caffeine peak in the blood within about 15–45 minutes of consumption.

They are then quickly metabolized by the liver.

Most people notice the strongest effects during this time, and many report feeling jittery, needing to urinate, and having sudden bursts of energy. These symptoms tend to go away as the caffeine starts to break down.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
