Answer:
45 degrees
Step-by-step explanation:
OK so
is L and N are equal you can represent that as 2x
the remaining angle should be 90 because right triangles always have a 90 degrees angle somewhere
you know that all three angles of a triangle add up to 180 so that's what the total is
2x+90=180
subtract 90 from both sides
2x=90
divide both sides by 2
x=45
Answer:
these are the answers of the questions x<-2 or x<2
Answer:
15595 bacteria will be present after 13 hours.
Step-by-step explanation:
Continuous population growth:
The continuous population growth model, for the population after t hours, is given by:

In which P(0) is the initial population and r is the growth rate.
Started with 5000 bacteria
This means that 
So

After three hours it grew 6500 bacteria:
This means that
. We use this to find r.







So

How many bacteria will be present after 13 hours?
This is P(13). So

Rounding to the nearest whole number
15595 bacteria will be present after 13 hours.
