At 7 a. m., a colony of 100 bacteria is placed on a petri dish where the population will triple (grows three times larger) every 6 hours.

Select ALL
statements which are true about the bacteria population.*

1 When the bacteria population reaches 900, 12 hours have passed since the colony
was placed on the petri dish.

2 Three hours after the colony is placed on the petri dish, there are 200 bacteria.

3 Three hours after the colony is placed on the petri dish, there are about 173 bacteria
in the colony

4 In the first hour that the colony is placed on the petri dish, the population grows by a
factor of 3^(1/6)

5Between 8 am and 9 am. the population grows by a factor of 3^(2/3).

8121 because

130,000 divided by 16 is 8121

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
