The travels you have described are:
(Middle floor) + 8 + 5 - 9 + 7 - 32
= (middle floor) + 20 - 41
= (middle floor) - 21 brought her to floor #1.
So Middle floor - 21 = 1
Add 21 to each side: Middle floor = 22
The building has (2 x middle floor) = 44 floors.
Answer:

Step-by-step explanation:
**This is a non-linear function and therefore <u>does not have a constant rate of change</u>. It will have a different slope depending on what points you use in the average rate of change formula:
To calculate rate of change, differentiate.
substitute y for
:

Take natural logs of both sides:

Apply the log rule
:

Differentiate with respect to
:

Mulitply both sides by
:

Replace
with 

Therefore, rate of change of the function is :

The rules of exponents tell you to add exponents in the numerator and subtract those in the denominator. A power of a power causes the exponent to be multiplied.

Answer:
A. 4
Step-by-step explanation:
Constant of proportionality (k) = y/x
We can use the coordinates of any point on the line to find k.
Let's use (2, 8)
Constant of proportionality (k) = 8/2
Constant of proportionality (k) = 4
