Answer:
On Graph B, at 0 seconds, the graph will be <u>0 or nothing.</u>
Then the graph will <u>increase</u> until 2 seconds.
Answer:
Both expressions are = to 11 when x is 2.
Therefore, the expressions are equivalent.
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: 86.5 in²
Step-by-step explanation: Circumference is2·pi·r= 32.97 in.
Radius r = 32.97 in/ 2pi = 5.247 in. Area is pi·r²
