Answer:
The circle's centre is at the position (3, 5), and it has a radius of 2
Step-by-step explanation:
First let's put it in a useful format by completing the squares:
x² + y² - 6x - 10y + 30 = 0
x² - 6x + y² - 10y = -30
x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25
(x - 3)² + (y - 5)² = 4
This tells us that the centre position is (3, 5) and the radius is √4, or 2

What is Savings?</h3>
Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.
Here, cost of mattress = $ 1399
cost of EMI = $ 78
Duration of EMI = 18 months
Total payable amount = 18 X 78
= $ 1404
Current account balance = $ 250
Per month savings = $ 50
Duration at which total balance is equivalent to payable amount
= (1404 - 250)/50
= 1154/50
= 23.08
Thus, At least 24 times he need to deposit $ 50 to paying off his total purchase.
