Question

Observe a figura determine a equação reduzida na circunferência q

Answer 1

2a) C(-3,0) R= 3
(x+3)² + y² = 9

b)C(0,0) R=3
x² + y² = 9

c) B(0,-4) C(2,-3)
Xcen=(2+0)/2 = 1

Ycen=(-4-3)/2 = -7/2

D²=(0-2)² + (-4+3)²
D²= 4 + 1
D= √5
R=(√5)/2

C(1,-7/2) R= (√5)/2
(x-1)² + (y+7/2)² = 5/4

d) D(3,0) E(0,4)
R²=(3-0)²+(0-4)²
R²= 9+16
R=5

C(3,0) R=5
(x-3)² + y²= 25
