Answer:
The answer is 9 hours
Step-by-step explanation:
From the initial population of 180 cells, the number grows by 8% every hour for the first 9 hours.
This represents a increased population of 108% the previous population.
108% = 108/100 = 1.08
So the new population after n hours is
180 x 1.08^n
When population is 360
360 = 180 x 1.08^n
1.08^n = 2
Take log of both sides
n x Log1.08 = Log 2
n = Log 2/Log 1.08
n = 9

The answer is 66.63!!!!!!
Answer: -4.5n - 4
Calculation/Explanation:
Distribute;
9 + (0.5)(7n) + (0.5)(-26) + -8n
= 9 + 3.5n + -13 + -8n
Combine Like Terms:
= 9 + 3.5n + -13 + -8n
= (3.5n + -8n) + (9 + -13)
