Step-by-step explanation:
The price p, in dollars, of a specific car that is x year old is modeled by the function p(x)=22,255(0.91)^x
a) to determine the cost of a 2 year old car, we will substitute 2 for x in the given function. Therefore
p(2)=22,255(0.91)^2
p(2)=22,255 × 0.8281 = $18673.655
Approximately $18674
b) to determine the cost of a 7 year old car, we will substitute 7 for x in the given function. Therefore
p(7)=22,255(0.91)^7
p(2)=22,255 × 0.51676101936 = 11500.51648579693
Approximately $11501
c) 0.91 indicates exponential decay rate. It is a fixed percentage by which the value of the car decreases every year. It is determined by (1 - rate of decay)
Answer:
-1
Step-by-step explanation:
You have to do rise over run.
One thing we already know is that the slope is negative because it's pointing in this direction \ <======
I will make a picture.
But the rise is 4 and the run is 4 so the slope is -1x or just -x
Hope this helps ya!!
you can estimate 17/18 - 3/7 = 65/126 to estimate the answer to 70/130. i think that's what you are asking
To solve, you will need to find the y intercept which in this case is on the graph. The find the slope's between the two points and calculate the average slope by adding the two then dividing. Hope that helps!
