Exercise 6.3
Q2. The rate at which the body eliminate a drug in millimetres per hour is given by
R(t)/dt=60t/(t+1)²(t+2)
Where t is the number of hours since the drug was administered if R(0)=0 is the current drug elimination , how much of the drug is eliminated during the first hour after it was administered ?The Fourth hour after it was administered?
Q3. The rate of change of the voting population of a city with respect to time t (in years) is estimated to be
dN/dt=100t/(1+t²)²
Where N(t) is in thousands.if N(0) is the current voting population, then how much will this population increase during the next 3 years?
Q4. An oil tanker a ground on the reef is losing oil and producing and oil slick that is radiating outward at rate approximated by
dr/dt=100/√t²+9
Where r is the radius in feet of the circular slick after 3 minutes find the radius of the slick after 4 minutes if the radius is r=0 where t=0
