Answer:
For n=6, the given vectors will be collinear.
Step-by-step explanation:
Collinear vectors are the vectors which lie on the same line or parallel lines. In order to find if two vectors are collinear, their ratio is found. If the ratio is same for all unit vectors then the vectors are collinear.
Given
The ratio of first unit vectors is:
In order for the vectors to be collinear the other ratio should also be 1/3
Writing it mathematically
Hence,
For n=6, the given vectors will be collinear.
Answer: Friday night. Least expensive ticket
Step-by-step explanation:
Friday night.: 48/3 =16 so each ticket costs $16
Saturday night 36/2= 18 so each ticket costs $18
Brother collects 96/6 = 16. So each person had enough for a $16 ticket. They can go to the Friday night concert. They paid for the least expensive ticket.
Answer:
Horizontal displacement = 100 km
Position with respect to sea level = -0.4km
Step-by-step explanation:
Let the displacement downwards be negative displacement and displacement upwards be positive.
The horizontal distance from the shore remains constant whereas the displacement from the sea level varies as the submarine moves.
The upward displacement = 3/5 km
Downward displacement = - 1/10 km and - 9/10 km
Total displacement = 3/5km - 1/10 km - 9/10km = - 2/5 km = - 0.4 km
Horizontal distance from the shore = 100km
Answer:
1/3 of a mile
Step-by-step explanation:
If she walks 2/3 of a mile everyday going to and from school. That makes it 1/3 of a mile in the morning and 1/3 of a mile in the afternoon. Which equals you total of 2/3
