Acertain bacteria population is known to doubles every 30 minutes. suppose that there are initially 80 bacteria. what is the size of the population after t hours? (hint: be careful with the exponent and the units of minutes versus hours.)

If an hour passes the bacteria would have tripled so 80 times 2 is 160.

If 2 hours pass the bacteria population would be 80 times 4 is 320.

I hope this helped you hon :)

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

the answer

b. they are parallel and will never intersect.
