Researchers recorded that a certain bacteria population declined from 800,000 to 500,000 in 6 hours after the administration of
kupik [55]

Answer:

We can assume that the decline in the population is an exponential decay.

An exponential decay can be written as:

P(t) = A*b^t

Where A is the initial population, b is the base and t is the variable, in this case, number of hours.

We know that: A = 800,000.

P(t) = 800,000*b^t

And we know that after 6 hours, the popuation was 500,000:

p(6h) = 500,000 = 800,000*b^6

then we have that:

b^6 = 500,000/800,000 = 5/8

b = (5/8)^(1/6) = 0.925

Then our equation is:

P(t) = 800,000*0.925^t

Now, the population after 24 hours will be:

P(24) = 800,000*0.925^24 = 123,166

Find NQ if NP = 13 cm and line l is a segment bisector.
Zielflug [23.3K]

Answer:

NQ = 26 cm

Step-by-step explanation:

A line bisector divides a line into two equal segments.

Given that line l is the bisector of segment NQ, it then means it divides NQ into two equal segments, namely, segment NP and segment PQ.

Thus, NP = ½ of segment NQ

Therefore, if NP = 13 cm,

13 = ½*NQ

multiply both sides by 2

2*13 = NQ

26 = NQ

NQ = 26 cm
