Sec4.6:#9 7. Population of a Country The population of a country has arelative growth rate of 3% per year. The government is tryingto reduce the growth rate to 2%. The population in 2011 wasapproximately 110 million. Find the projected population forthe year 2036 for the following conditions.(a) The relative growth rate remains at 3% per year.(b) The relative growth rate is reduced to 2% per year.8. Bacteria Culture It is observed that a certain bacteria culturehas a relative growth rate of 12% per hour, but in the presenceof an antibiotic the relative growth rate is reduced to 5% perhour. The initial number of bacteria in the culture is 22.the projected population after 24 hours for the followingindconditions.(a) No antibiotic is present, so the relative growth rateis 12%.(b) An antibiotic is present in the culture, so the relativegrowth rate is reduced to 5%.9. Population of a City The population of a certain city was112,000 in 2014, and the observed doubling time for the pop-ulation is 18 years.(a) Find an exponential model n(t) = no2la for the popula-tion t years after 2014.(b) Find an exponential model n(t) = noe" for the popula-tion t years after 2014.(c) Sketch a graph of the population at time t.(d) Estimate how long it takes the population to reach500,000.
