Find the center and radius of the circle whose equation is x^2 + y^2 - 6x - 2y + 4 = 0

center(3,1) radius square root of 6

Step-by-step explanation:

(x^2-6x+9)+(y^2-2y+1)=6

(x-3)^2+(y-1)^2=6

29 is the correct answer

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
