The answer is 7 3/4 inches.
I noticed the word "train" in the problem and I knew I had to help you! :)
Answer:

Step-by-step explanation:
we have a exponential function of the form

where
y is the population of bacteria
a is the initial value
r is the rate of growth
x is the number of hours
we have
a=3,000 bacteria

For x=2, y=3,300
substitute


Apply square root both sides




substitute in the equation


<u><em>Predict how many bacteria will be present after 16 hours</em></u>
For x=16 hours
substitute


Answer: A
Step-by-step explanation:
A linear function is described as:
https://tex.z-dn.net/?f=f(x)%20%3D%20ax%20%2B%20b
When the value of x = 0, then you're left with
https://tex.z-dn.net/?f=f(x)%20%3D%20b
In this question, the speed of sound is the linear function while the temperature is the independent variable. When T = 0, you're left with
https://tex.z-dn.net/?f=S(0)%20%3D%20331.4
Which means the speed of sound in air when temperature is 0°C is 331.4m/s.
Answer:
21.71
Step-by-step explanation:
1) you need to order then by the size
3, 13, 14, 16, 27.42, 37.97 ,64, 95
2) if there is an odd amount of numbers then the median would be the center term. but if it an even number then you add the two middle terms together and divide them by 2.
16+27.42= 43.42
43.42 divided by 2=21.71
Hope this helped
