Answer:
r(t) and s(t) are parallel.
Step-by-step explanation:
Given that :
the lines represented by the vector equations are:
r(t)=⟨1−t,3+2t,−3t⟩
s(t)=⟨2t,−3−4t,3+6t⟩
The objective is to determine if the following lines represented by the vector equations below intersect, are parallel, are skew, or are identical.
NOTE:
Two lines will be parallel if 
here;

Thus;



∴

Hence, we can conclude that r(t) and s(t) are parallel.
Answer:
yes
Step-by-step explanation:
6(1)-2>3
6-2>3
4>3
So we need to compare them at the sam ounches
find the least common multiple (the smallest number that they will both multiply into)
first find the factors and group them all together, delete any repeats
6=2*3
8=2*2*2
least common multiple=2*2*2*3=24
so 6 bags=2.46
multiply by 4 to get 24
24 bags=9.84
so 8 bags=3.20
multply by 3
24 bags=9.60
9.84>9.60 so
the 8 ounce bag is less expensive
Use the Pythagorean theorem:
x = √(12.7^2 - 6.2^2)
x = √(161.29 - 38.44)
x = √122.85
x = 11.08
Round to 11.1 m
