Answer:
B
Step-by-step explanation:
Answer:
p=3
Step-by-step explanation:
9p+14=2p+35
Subtract 2p from each side
9p-2p+14=2p-2p+35
7p +14 = 35
Subtract 14 from each side
7p +14-14 = 35-14
7p = 21
Divide by 7
7p/7= 21/7
p=3
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
