Answer:
The equation of the circle having centre (-5,-9) and radius r=3 is
x² + 10 x +y² + 14 y + 65 = 0
Step-by-step explanation:
<u>Explanation</u>:-
From graph The centre of the circle C( -5 , -7)
The radius of the circle r = 3cm from the centre of the given circle
The equation of the circle
From graph the centre ( h, k) = ( -5,-7) and r = 3cm
x² + 10 x +25 +y² + 14 y + 49 =9
x² + 10 x +25 +y² + 14 y + 49 -9=0
The equation of the circle
x² + 10 x +y² + 14 y + 65 = 0

Answer:
Number of Volleyballs = 8 balls
Step-by-step explanation:
Given:
Total number of balls = 30 balls
Fraction of soccer ball = 2/5 balls
Fraction of basketball = 1/3 balls
Rest are Volleyballs
Find:
Number of Volleyballs
Computation:
Number of Volleyballs = Total number of balls - Total number soccer balls - Total number of basketballs
Number of Volleyballs = 30 - (30)(2/5) - (30)(1/3)
Number of Volleyballs = 30 - 12 - 10
Number of Volleyballs = 30 - 22
Number of Volleyballs = 8 balls
