Help with what? there is nothing on this page for me to help u with .
Let
The origin of coordinates the tree
r1 = vector position of the child 1.
r2 = vector position of the child 2
Child 1:
r1 = (12i + 12j)
Child 2:
r2 = (-18i + 11j)
The scalar product will be given by:
r1.r2 = ((12) * (- 18)) + ((12) * (11)) = - 84
The scalar product of their net displacements from the tree is -84m ^ 2
Answer:
(-1,8)
(4,-27)
Step-by-step explanation:
y+7x=1
Let x = -1 and find y
y+7(-1)=1
y -7 =1
Add 7 to each side
y-7+7 = 1+7
y = 8
(-1,8)
Let x = 4 and find y
y+7(4)=1
y +28 =1
Subtract 28 from each side
y+28-28 = 1-28
y = -27
(4,-27)
2 16/100 this would be that as a fraction. I'm a little confused as to what your asking
![\sqrt{[(6-(-6)]^2+[(2-(-2)]^2} = \sqrt{12^2+4^2} = \sqrt{16} =4 \sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%5B%286-%28-6%29%5D%5E2%2B%5B%282-%28-2%29%5D%5E2%7D%20%3D%20%5Csqrt%7B12%5E2%2B4%5E2%7D%20%3D%20%5Csqrt%7B16%7D%20%3D4%20%5Csqrt%7B10%7D%20)
