Answer:
a) order the number from least to greatest
8/9> -3.3 > -8 > -15
b) absolute value
|8/9| = 8/9
|-3.3| = 3.3
|-8| = 8
|-15| = 15
order 15 > 8 > 3.3 > 8/9
c) difference in the order in part (a) and (b) is because larger value with negative sign is the smallest.
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
Just look up a calculator of that type of work on your phone and it will help I promise
I won't do this for you, but I can give you a hint. Replace your f variable with -2, -1, 0, 1, and 2. Then take said f variable and put it in your y boxes. Then just get a calculator and do the work on there. It should be pretty easy.
