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:
48
Step-by-step explanation:
8x3x2= 48
1 batch=2 1/2 cups of flour
3 1/2 batches= x cups of flour
1batch 3 1/2 batches
___________ = _____________
2 1/2 cups x cups
Cross multiply
1x=8 3/4
divide both sides by 1
x=8 3/4 cups
Answer= 8 3/4 cups of flour
