You always get from one term to the next by adding 6:




So, the rule is "add 6"
2000=1800(1.04)^t,,log(1.11)/log(1.04)=t use the calculator,,,hope it helps :-)
Answer:

and

respectively.
Step-by-step explanation:
The given trigonometric equation is

We divide both sides by
to get,

This implies that,

We take the inverse tangent of both sides to get,




Since the tangent ratio has a period of
, another solution is

to the nearest degree.
In the third quadrant,




The solutions are

The value of x that satisfies the equation if x lies in the second quadrant is 
The value of x that satisfies the equation if x lies in the third quadrant is
8260 divided by 4 is 2065.
The answer is 2065 tangerines.
