Answer:#1 = 16
#2 = 4
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
x^2 + y^2 - 8x + 12y + 40 = 0
x^2 - 8x + y^2 + 12y = -40
Complete the square on the x and y terms:-
(x - 4)^2 - 16 + ( y + 6)^2 - 36 = -40
(x - 4)^2 + (y + 6)^2 = -40 + 16 + 36
(x - 4)^2 + (y + 6)^2 = 12
So the centre is at (4, -6) and the radius is √12.
This is all the picture showed omg toooo hard
Answer:
approx. 1/2
part B: 11/24
1/24, explanation in step by step
Step-by-step explanation:
10 /12 is close to 1
3/8 is close to 1/2
Part B:
10/12 - 3/8
10/12 = 20 /24
3/8 = 9/24
20/24 - 9/24 = 11/24
1-1/2=1/2
Part C:
1/2 - 11/24 = 12/24 - 11/24 = 1/24
I think my answer is reasonable because when I subtracted my answer from my estimate, I got a number very close to 0
1/2
Since it is asking for absolute value you just need to forget about the negative sign.
