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 :
10xt=190
T represents the amount of trips and 10 represents the amount of money she spends each trip. Since she has $190 already it will be on the other side of the equation after the equal sign
Answer:
A. Right angle traingle Is the answer
The answer is 256.25
EXPLANATION
Let represent the number.
Then, 
We cross multiply yo obtain,
We now divide both sides by 16.
This will give us,
Therefore the number is 256.26
100%/x%=27.5/17.16
(100/x)*x=(27.5/17.16)*x
100=1.60256410256*x divide both sides of the equation by (1.60256410256) to get x
100/1.60256410256=x
62.4=x
x=62.4
