The following problem could be expresses as
c=1/3b or 3c=b
36/3000 ? maybe 1/5 ....................................
Answer:
d. 
Step-by-step explanation:
The given trigonometric equation is;

Recall that;



The cosine function is negative in the second and third quadrant.


Both are horizontal, both are parallel to the x-axis, both are below the x-axis.These were just visual comparisons, which may not be what you need. I found this on yahoo.

Given: Purchasing value of car = $19,700,
Rate of depriciation = 10% per year.
To find: Final value of car after after 6 years.
Solution : Because rate of car is being depriciated exponential. So, we would exponential formula.

Where, P is the purchase value, k is the rate of depriciation and t is the number of years.
Plugging values P = 19,700, r=10% that is 0.10 and t= 6 in above formula.


A= 19,700 (0.54881163609)
A= 10811.5892311.
Rounding to the nearest penny (two decimal places0.
A= 10811.59.
Therefore, Final value of car after after 6 years = $ 10811.59
