It would be -40,20 and -10,-20
Arcs are just sections of the circle
so lets say you had a pizza
and you put some points on the crust, the legnth of the crust from point to point is that arc
example
if you put poins A and B, then arc AB is the crust between points A and B
arcs can include other points as well
and arc AB=arc BA
so
I wil name easy arcs first
arc AB
arc BC
arc CD
ard DA
now ones that include others
arc AC
arc BD
so the arcs you might want to list are
arc AB
arc BC
arc CD
ard DA
arc AC
arc DB
Answer:
261
Step-by-step explanation:
450 (.58)= 261
check answer 261/450 =.58
Answer:
slope: -1/2
Y-intercept: -1
Step-by-step explanation:
Get Y by itself by subtracting x on both sides
2y= -x -2
Now divide both sides by 2 to cancel the two connected to the y:
Y = -1/2x -2/2
So y= -1/2x -1
Y=mx+b so m is the slope and b represents the y-intercept
Well the quadratic formula is just:
x = -b + and - the square root of b^2 - 4ac all divided by 2a. You just plug in numbers and get an answer for x.
