4 0

Answer:

Step-by-step explanation:

hello :

(x² - 10x) + (y² - 2y) + 15 = 0

(x² - 10x+25-25) + (y² - 2y+1-1) + 15 = 0

(x² - 10x+25)-25 + (y² - 2y+1)-1 + 15 = 0

(x-5)²+(y-1)² = 11

the center is (5;1) and radius √11

Answer:

- 508

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus

$a_{81}$ = - 28 + (- 6 × 80) = - 28 - 480 = - 508
