The exponential growth and decay model describes the amount of a particular drug in a patient's bloodstream a certain time after the drug was given to the patient. The amount of this drug in the bloodsteam decreases at a rate of 35% per hour. If 2.5 units of this drug were given to the patient 10 hours ago, then how many units remain in his bloodstream now?

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
