Answer:
X+20=2 i think this is a little above my head
It will take 7/8 of a minute because you just multiply 1/8 by 7
Answer:
2
Step-by-step explanation:
Maybe they got confused or could not read her handwriting well because im pretty sure it is 2
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
