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
You are given following <u>data</u>:
15 logs - 10 hours,
9 logs - x hours.
Use <u>proportion</u> to determine unknown <u>value</u> of x:

Then

Answer: 6 hours
A function is a relation that has one output for a given input.
For the first one, there is no one x value with two or more y values so it is a function.
The second example is also a function because a certain value can only have one cube root.
For problem number 3 input "-3" for every instance of x in h(x).
So, h(-3)=2(3^2)-1= 17

Answer:
24 months
Step-by-step explanation:
Cross-multiply
0.5 inches -------------- 1 month
12 inches ---------------- x months
0.5/12 = 1/x ===> 0.5x = 12 ===> x = 12/0.5 ===> x = 24 months
