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:
Option 4.7% = 3,500 x 4.7% =$164.50 simple annual interest.
82.25 this is what Scott will pay in 6 months at simple interest.
Option 4.2% =3,500 x (1 +0.042/12)^6 =3,500 x 1.0035^6=$3,574.15.
3,500 =$74.15 this is what Scott will pay in 6 months at compounded interest.
The compound option is cheaper by: 74.15 =$8.10.
Answer:
A) (4, 36)
Step-by-step explanation:
Substituting 4 into the equation gets y = 9(4), which is equal to 36.
