They are intersecting at 0,0.
One square on that chart is 2 units.
You can see this since it goes -10 then skips one then goes to -6.
The one in between is -8.
On every side of the intersection there is a 2 or -2.
2 - 2 or -2 + 2, depending if it's positive or negative, is 0.
So the lines are intersecting at 0,0.
Hope this helps! :)
Answer: y=-8-4/1
Step-by-step explanation:
Answer:
24, -38, 62, -100
Step-by-step explanation:
The recursive formula is a_n = a_(n-2) - a_(n-1)
so. we try this 4 times after the -14 term
a_3 = -4 = 2 - 6 = a_1 - a_2
...
a_6 = a_4 - a_5 = 10 - (-14) = 24
a_7 = a_5 - a_6 = -14 - (24) = -38
a_8 = a_6 - a_7 = 24 - (-38) = 62
a_9 = a_7 - a_8 = -38 - 62 = -100
a_10 = a_8 - a_9 = 62 - (-100) = 162
Area = Pi * r^2
'
r = 7 / 2 = 3.5
area = 3.14 * 3.5^2
area = 3.14 * 12.25
area = 38.465 m sq
