Answer:
Step-by-step explanation:
Given that ||v|| = 2 and ||w|| = 3, and the angle between v and w is 120 degrees
We know by definition of dot product and properties that
where t is the angle between them
Using this we find
(a) v·w =
(b) ∥2v+w∥
(c) ∥2v−3w∥
Answer: it is (-2,2)
Step-by-step explanation:
You go on the -2 point on the x axis and 2 block up from that point to get (-2,2).
30% = 3/10
Number of hours you sleep = 24hours × 3/10
= 24hours ÷ 10 × 3
= 2.4hours × 3
= 7.2hours
Hope this helps! :)
