A person has a blood alcohol level of 200 mg/dL (milligrams per deciliter). If the amount of alcohol in the blood decays exponentially, and after 2 hours, 98 mg/dL remain, find an exponential model for the person's blood alcohol level f(t) where t is the time in hours.  f(t) =  estimate the person's blood alcohol level after 3 hours. (Round your answer to one decimal place.)  mg/dL =   Part 2 (image) Model the data using an exponential function f(x) = Abx.

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
