Answer:
Exponential Function
Step-by-step explanation:
The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.
This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:
Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.
Answer: Percentage increase: 57%
Percent increase if the airline charges an additional 50: 14.5% or 15%
Depends if your teacher wants more accurate results with the decimal, or rounded up with 15.
Step-by-step explanation:
Ill explain in the comments bc for some reason its not letting me put it here
Multiply the amount she puts in the account every week by the number of weeks (w) and add that to what she already has saved:
20w + 600 >= 2000
The answer is:
v ≈ 1272.35 in^3
Sorry if this does not help.
Answer:
The equation would be y = x + 5, in which x is the number of weeks and y is the number of books he has.
Step-by-step explanation:
We know this because even at 0 weeks, he still has 5 books. Therefore we put this as the constant at the end. Then we can add the number of weeks since the rate is one book per week.
