You are moving a total from - 13  to + 22. That alone is enough to make someone wonder why they live where they live. (The weather where I live can can do exactly this). 

What is the range of the temperature?
You might think it was -13 to 22. It sounds like it could be 9 degrees. 22 - 13 = 9. 

That is not right. The actual movement is absolute value of (-13) which will be added onto 22.

So the temperature movement is
13 + 22 = 35 degrees.

Hours.
The hours are not as hard to figure out. From 3am to 10 am is 7 hours

Degrees per hour
<em>Formula </em>
Degrees / hour = degrees / hour
degrees = 35 degrees
hour = 7 hours.

Degrees / hour = 35 degrees / 7 hours = 5 degrees / hour.

The average change of temperature per hour is the difference in temperature divided by the difference in hours.

3 a.m.     10 a.m.  ----> difference in time: 10 - 3 = 7
-13           22         ----> difference in temperature: 22 - (-13) = 35

average change of temperature per hour: 35/7 = 5

Answer: 5 degrees per hour

Which temperature is colder? -10 degrees or -13 degrees
frez [133]

Answer:

-13

Step-by-step explanation:

The more negative the number, the colder it is

-13 is more negative than -10

-13 < -10

-13 is colder

Can anyone tell me how you could describe this answer to the equation?

The end behavior of the given polynomial is that as x → -∞ or  x → ∞, then, f(x) → 5

<h3>What is the end behavior of the Polynomial?</h3>

We are given the polynomial;

f(x) = 5x/(x - 25)

Now, we want to find the limits as x → ±∞. Let us rearrange the given polynomial to get; f(x) = 5/(1 - (25/x))

Thus, applying limits we have;'

lim x → ±∞ [5/(1 - (25/x))]

From algebraic limit laws we know that;

If f(x) = k, then;

lim x → +∞ [f(x)] = k

Also, lim x → -∞ [f(x)] = k

Thus, applying limits at infinity to our polynomial gives;

lim x → ±∞ [5/(1 - (25/x))] = 5/(1 - 0) = 5

This is because lim x → ∞ for 1/x is 0.

Thus, f(x) has horizontal asymptotes at y = 5

Thus, we conclude that the end behavior is that as x → -∞ or  x → ∞, then, f(x) → 5

A water hose at a fire station leaked 80 gallons of water water leak at a rate of 20 gallons every 4 minutes at this rate, how m
tigry1 [53]

It would be 16 minutes because you would divide 80 by 20 and you get 4 so now you multiply 4 by 4 and you get 16
