square root(-108) - square root(-3) =8.66025404 i
        
             
        
        
        
X² - 4x    + y² - 8y    = 5
Complete the square:
x² - 4x + (4) +  y² - 8y + (16)    = 5 + (4) + (16)
→  (x - 2)²    +  (y - 4)²    = 25
Center: (2,4)
radius: √25 = 5
        
             
        
        
        
Answer: In 5 years it will be worth £455
Step-by-step explanation:
Step 1 
 Given 
The cost of the T.V. for Colin = £530.
The rate of depreciation per year = 3%
Time/ period = 5 years
Formulae to be used 
F = P  X (1 - r) ^ n
where
F = the future value after depreciation
P = the present value.
r =the interest rate per time period 
n = the time/ periods
 Step 2--- SOLVING
F = P  X (1- r) ^ n
F= 530 x (1-0.03) ^ 5
=530 x 0.858734
=£455.129
 Rounding up to the nearest penny where appropriate = £455
