Answer:
22.4 hours
Step-by-step explanation:
The population of bacteria is modelled by the equation:
From the the question, the initial population of bacteria is 720.
So after 26 hours, we have:
This implies that:
We want to find how long it will take for there to be 1310 bacteria present.
To the nearest tenth , it will take 22.4 hours
1/2 - 5/13 = 3/26 = 0.115
Because: 1/2 - 5/13 = 1 x 13 ÷ 2 x 13 - 5 x 2 ÷ 13 x 2 = 13/26 - 10/26
13/26 - 10/26 = 13 - 10 ÷26 = 3/26 or 0.115.

Answer:
Parallel?
Step-by-step explanation:
6x = 2y + 10
3x = y + 5 divide both sides by 2
y = 3x + 5/3
Sam slopes, different intercepts.
