Answer:
(x+1)^2+(y+1)^2=13
Step-by-step explanation:
Equation of a circle: (x – h)^2 + (y – k)^2 = r^2
center: (-1, -1)
radius: sqrt(6^2+4^2)/2=sqrt(52)/2=2sqrt(13)/2=sqrt(13)
Substitute those values in to get
(x+1)^2+(y+1)^2=13
Answer:
-13/40 or -0.325
Step-by-step explanation:
3= 3 thirds + 3 thirds + 3 thirds = 9 thirds
2/3 = 2 thirds
9 + 2 = 11 thirds. (11/3)
16cm
Dividing 81.9 cm^2 by 4.9cm will give you about a 16 cm height.
:) Good Luck
Answer:
0
Step-by-step explanation:
x=1 and y=-3
so 3x^2 + y = 3*1^2 + (-3)
= 3* 1 -3
=0
