Answer:

Step-by-step explanation:
Using the exact values of the given trig functions, then
sin45° × sin30° × cos60°
=
×
×
= 
This can be solve by using the formula
D = P( 1 – i)^n
Where d is the depreciation value after n years
P is the initial value
i is the depreciation rate
n is the years
D = 1/3 ( 1800)
D = 600
So
600 = 1800 ( 1- 0.45)^n
Solve for n
