Answer:
The half life of the car is 3.98 years.
Step-by-step explanation:
The value of the car after t years is given by the following equation:

In which V(0) is the initial value and r is the constant decay rate, as a decimal.
The value of a certain car decreases by 16% each year.
This means that 
So



What is the 1⁄2-life of the car?
This is t for which V(t) = 0.5V(0). So







The half life of the car is 3.98 years.
Answer:
x = 36/5
Step-by-step explanation:
Subtract 6 from both sides
x/3+6-2x-6 = -6-6
Simplify
x/3 - 2x = -12
Multiply both sides by 3
x/3 * 3 - 2x * 3 = -12 * 3
Simplify
-5x = -36
Divide both sides by -5
-5x/-5 = -36/-5
Simplify
x = 36/5
The two black circles represents "The selling prices that produces no profit." If the selling is 10, the profit is 0. If the selling price is 60, the profit is 0.
The selling price that provides the maximum profit is represented by the red dot. It is between the selling price of 30 and 40. Its maximum profit is equal to 12,000.
