Write the equation of the circle graphed below

(x-4)² + (y-3)² =29

Step-by-step explanation:

The equation of a circle is

(x-h)² + (y-k)² = r², where (h, k) is the center of the circle and r is the radius.

In this circle, the center is at (4, 3)  

(x-4)² + (y-3)² = r²

and we have point (-1 ; 1)

r²=(-1-4)² + (1-3)² = 25+4=29

(x-4)² + (y-3)² =29

a. is correct

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
