Answer:
Step-by-step explanation:
Long way:
Find the midpoint (M) of AB, find the slope(m) of the line AB, then find the equation of the line through M with slope -1/m, which is the perpendicular bisector of AB.
Short way:
The perpendicular bisector of (x₁,y₁) and (x₂,y₂): 2(x₂-x₁)x + 2(y₂-y₁)y = x₂²-x₁²+y₂²-y₁².
Here this is 2(1-(-4))x + 2(6-4)y = 1²-(-4)²+6²-4² which is 10x + 4y = 5.
Answer: Set the radicand in
√x+6 greater than or equal to 0
to find where the expression is defined. x+6≥0
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
10 x 6 = 60
5 x 6 = 30
60 - 30 = 30
6. the name is circle x (due to the central point)
7. the diameter is segment WY
8. radius is 1/2 of the diameter so 1/2(15) = 7.5 meters
9. diameter is 2 times the radius so 2(4) = 8 cm
10. segment XW, segment XZ, segment XY
11. arc YW, arc WZ, arc ZY
