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)

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
