Answer:
The answers are:
- 2u = <10,2>
- -3u = <-18,-6>
- u+v = <11,3>
- 3u-4v = <-9,-5>
Step-by-step explanation:
Given vectors are:
u = <5,1>
v = <6,2>
The vectors are given in the form of ordered pairs, the operations can be applied on the coordinates of ordered pairs
Now,


Now we have to add two vectors
In order to add two vectors, their respective coordinates are added:
So,

And

Hence,
The answers are:
- 2u = <10,2>
- -3u = <-18,-6>
- u+v = <11,3>
- 3u-4v = <-9,-5>

Answer: 
Step-by-step explanation:
Given: The approximate height of Mountain Rainier h= 2.7 miles
The radius of earth = 3959 miles.
Let d be the distance to the horizon from this point.
We know that the line of sight to the horizon , the radius at the horizon and the radius at the mountain from a right angle triangle.
Therefore, by Pythagoras's theorem we have

Hence, the distance to the horizon from this point=
