Answer:
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:
I believe it is, 30 minutes of running.
Explanation:
If she spends 12 minutes walking, that means she’s done 6 ‘sets’ of two minutes.
Then, you just have to multiply 6 by 5 and then you get 30.
Midpoint formula = (-9 + 6) / 2 = -3/2
P^5 / P^2
The base are equal, so we should to subtracting the powers only
Dividing exponential expressions
P^5 / P^2 = P^(5-2)
:. = P^3
