Question

ayuda!!!!!!
para matemática :( por favor

Answer 1

Respuesta:

I

x^2+y^2=3^2=9

x^2+y^2=4^2=16

x^2+y^2=6^2=36

x^2+y^2=4.5^2=18.5

II

centro (0,0) para todas

Radios

r1=raiz(4)=2

r1=raiz(25)=5

r1=raiz(64)=8

r1=raiz(1)=1

III

....(x-2)^2+(x-(-3))^2=5^2

(x-2)^2+(x+3))^2=25

....(x-2)^2+(y-0)^2=2^2

(x-2)^2+(y)^2=4

.....(x-(-2))^2+(y-(-7))^2=9^2

(x+2)^2+(y+7)^2=81

.....(x-3)^2+(x-(-1/2))^2=3^2

(x-3)^2+(x+1/2)^2=9

IV

C(h,k),r

....C(3,2) r=raiz(4)=2

.....C(-3,-2) r=raiz(4)=2

.....C(-7,-5) r=raiz(3)

......C(1/2,3/4) r=raiz(100)=10
