Answer:
Bacterial population at the time of 10 hours = 1040000
Step-by-step explanation:
Let the function that defines the bacterial population after 'x' hours is,
p(x) = a(b)ˣ
Where a = Initial population
And 'x' = Duration or time
Since bacterial population is getting doubled every hour,
2a = a(b)¹
b = 2
Therefore, function will be,
p(x) = a(2)ˣ
From the graph attached,
Point (5, 32500) lies on the graph of the function.
32500 = a(2)⁵
a = ![\frac{32500}{32}=1015.625](https://tex.z-dn.net/?f=%5Cfrac%7B32500%7D%7B32%7D%3D1015.625)
Therefore, the function will be,
p(x) = 1015.625(2)ˣ
For x = 10 hours,
p(10) = 1015.625(2)¹⁰
= 1040000 bacteria
The answer for this question is -20.You have to subtract -15-5 and that’s what you get.
I believe the answer should be -4+x= -4x.
I hope this helps :)
