This equation is known as the equation for exponential growth/decay:
Since the car is worth no more than $1,900 when bought, we can rewrite the above equation as:
<u>a is the initial value, and b is the growth factor, x is the </u><u>amount of</u><u> time that passes.
</u>So, we can plug in all that information (it's negative because the car's value goes <em>down</em>):
<u>
</u>That's you

Answer:
Width: 90m
Length: 120m
Step-by-step explanation:
Width = 3/4x
Length = x
2(3/4x) + 2x = 420m
6/4 x + 2x = 420m. (6/4 + 2 = 7/2)
7/2x = 420m
7x = (420)*(2)
x = 840/7 = 120
Width = (120)*(3/4) = 90
Length: 120
2(90)+2(120)= 420m
Answer:
In 30 minutes:
The minute hand moves a distance of 25.13 inches
In 20 minutes:
The minute hand moves a distance of 16.76 inches
Step-by-step explanation:
When 60 minutes are completed, the minute hand of the relog makes a complete revolution. The distance s that the minute hand travels when making a complete revolution is:
Where r is the radius of the circumference, and in this case, the radius of the minute hand.
So:
s = 50.27 inches.
In 30 minutes (which is half of 60) the minute hand covers only half a revolution. Then the distance traveled in 30 minutes is 
inches
In 20 minutes (which is one third of 60) the minute hand only travels a third of a complete revolution. Then the distance traveled in 20 minutes is 
inches
