Manny Brought a brand new car in 2012 for $28750. if the car depreciates by 12% each year, write n exponential function to model

alexira [117]

The formula for exponential decay is
$y=a(1-r)^{x}$

where a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 . 2018-2012 = 6 years)

$y=28750(1-0.12)^{6}$

y ≈ 13351.62

The average cost of a home in a certain neighborhood ranges from $225,000 to $385,000. Write an absolute value inequality to mod

nataly862011 [7]

Answer:

D. |C -305,000| ≤ 80,000

Step-by-step explanation:

Such an equation will say that the difference from the average of these values is at most half of their difference.

| C -(225000+385000)/2 | ≤ (385000 -225000)/2

|C -305,000| ≤ 80,000 . . . . . matches choice D
