A population of amoebas in a petri dish will triple in size every 20 minutes. At the start of an experiment the population is 800. The function y = 800.3,
where x is the number of 20 minute periods, models the population growth. How many amoebas are in the petri dish after 3 hours?

Step-by-step explanation:

The population of amoebas in a dish becomes three times in size after every 20 minutes.

Now, the equation that models the situation is, , where y is the number of amoebas and x is the number of 20 minutes passed.

Now, the above equation also shows that the initial numbers of amoebas at the start of the experiment were 800.

Therefore, after 3 hours i.e. 180 minutes i.e. 15 numbers of 20 minutes (x = 15) the population of amoebas will be, (Answer)

if this is really you s much. i only have 3 points left and i have 2 questions to ask

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
