Answer:


Step-by-step explanation:
First we define two generic vectors in our
space:


By definition we know that Euclidean norm on an 2-dimensional Euclidean space
is:

Also we know that the inner product in
space is defined as:

So as first condition we have that both two vectors have Euclidian Norm 1, that is:

and

As second condition we have that:


Which is the same:

Replacing the second condition on the first condition we have:

Since
we have two posible solutions,
or
. If we choose
, we can choose next the other solution for
.
Remembering,

The two vectors we are looking for are:

Answer:
≥ closed dot
< open dot
≤ less than or equal to closed dot
There are the missing blanks
This is a 30-60-90 triangle
opposite side of rigt angle=2x
opposite side of 60 degrees is x√3
opposite sides of 30 degree is x
the right angle is at the base of the building so therefor
200=x
2x=distance from surveor to top of building and x√3=height of building
x=200
200√3≈346.41
the answer is 346.41 feet
Answer:
25%
Step-by-step explanation:
1925 - 1440 = 485
X/100 = 485/1925 (what percent is 485 of 1925) (%/100=is/of)
(485 x 100) / 1925 (cross multiply)
48500/1925 = 25%
