Answer:
B
Step-by-step explanation:
Divide 18 by one third and see what ya get
then 6, then 2. BOOM!
<span> we know the length of the cable is 9m.
That means the magnitude of </span><span><span>r<span><span><span>AB</span></span><span></span></span></span>=9</span><span>m.
The unit vector, denoted u, is each of </span><span>r<span><span><span>AB</span></span><span></span></span></span><span> divided by the magnitude.
</span>u=<span>(<span><span>x/9</span><span></span></span>i−<span>y/9<span></span></span>j−<span>z/9<span></span></span>k<span>)
</span></span><span>We can also figure out the unit vector of F.
</span>u=(350i - 250j - 450k)/√(350² +(-250)² +(-450)²)
u=0.562i−0.401j−0.723<span>k
</span>
<span>Force F is directed from point A to B, then both unit vectors must be equal.
Therefore
</span>(x/9i−y/9j−z/9k)=0.562i−0.401j−0.723k
<span>We can now solve for each term
x/9=0.562----- > x=5.058 m
-y/9=-0.401--------- > y=3.609 m
-z/9=-0.723------- > z=6.507 m
The answer is
the coordinates of point a
(5.058,3.609,6.507)

Given :
Length of parade ,
.
Breadth of parade ,
.
5 people can fit into a
area.
1 mile = 5280 ft .
To Find :
The size of the crowd.
Solution :
Area of parade ,

Also , 5 people can fit in
area .
So , number of people fit in A is :

Therefore , 95040 can fit in the parade .
Hence , this the required solution .
1.
d = rt
13 = r*3
r = 13/3
2.
v = r + at
a = (v-r)/t
