If you look careful,the line is passing throw the middle of the square which that means 0,5=>1/2
Answer:
This ans is easily solved by using algebraic identities a²- b² = (a+b) (a-b)
Step-by-step explanation:
1. convert into Identity
2. solve quadratic equation that formed.
Step-by-step explanation:
a-2=3+6a/3
By cross multiply
3(a-2)=3+6a
3a-6=3+6a
-6-3=6a-3a
-9=3a
a=-3
we can use formula
now, we can find a and b
Initially , price is 500
so,
At
now, we can plug back
At
we can use it and find b
now, we can solve for b
and we get
so,
annual depreciation rate is 27.144%.......Answer
