The number of bacteria in a culture is increasing according to the law of exponential growth. Initially there are 300 bacteria and after 4 hours there are 900 bacteria. How many bacteria will there be after 6 hours? Round your answer to the nearest whole number.

Expert Solution

Given initially there are 300 bacteria

after four hours there are 900 bacteria

we want find how many bacteria after 6 hours

to find this we can use Exponential Growth model

by exponential growth model

t is the time in hours

to find growth factor, given for 4 hours number of bacterias are 900

substituting

so bacteria growth model is given by

we want to find population of bacteria after 6 hours

for that put t =6 in bacteria growth model

rounding to nearest whole number

so number of bacteria after 6 hours is 1559

a) Suppose that 650 bacteria are present initially in a culture. If the number of bacteria triple every 5 hours, how long is it until there are 50,000 bacteria in the culture? b) The half-life of C14 is 5730 years. If a fossilized leaf contains 42% of its normal amount of C14, how old is the fossil? c) HOw long does it take for an investment to double in value if it is invested at 3.6% compounded quarterly?

Diseases tend to spread according to the exponential growth model. In the early days of AIDS, the growth factor (i.e. common ratio; growth multiplier) was around 2.1. In 1983, about 1800 people in the U.S. died of AIDS. If the trend had continued unchecked, how many people would have died from AIDS in 2005? ______________________people (Note: once diseases become widespread, they start to behave more like logistic growth, but don't worry about that for the purpose of this exercise) 2...
