Answer:
6
Step-by-step explanation:
The formula for doubling time is given as:
P(t) = Po(2)^t/k
Where:
P(t) = Population after time t = 28,284
Po = Initial Population = 20,000
t = time = 3 days
k = doubling time = ?
28,284 = 20,000 × (2)^3/k
Divide both sides by 20,000
28,284/20,000 = 20,000/20,000 × (2)^3/k
1.4142 = (2)^3/k
2^1/2 = (2)^3/k
Divide both sides by 2
1/2 = 3/k
Cross Multiply
k × 1 = 2 × 3
k = 6
Therefore, the doubling time(k) of the bacteria is 6
Commutative property of multiplcation.
An identifier for the property of multiplcation is by multiplying it by 1. Therefore the answer remains the same.

alls you do is plug in the numbers its not hard sweetie
Check the picture below.
y=0x+2 meaning the slope is equal to 0
If you think about this question you'll see that our two points have the same y coordinate
This means that the slope is equal to 0
so we have
y=0x+b
If we plug in -3 for x and set the equation equal to 2 we can find b
0+b=2
b=2
0x+b=y
Hope this helps!
