Hope this helps! :)
Answer:
B
Step-by-step explanation:
Compute the derivative of 
at 
- this will be the tangent vector - then normalize it by dividing it by its magnitude to get the unit tangent vector 
.
Do you want the answer for question 1!? It's already done! It says Given right there, that's an example answer :)
Greetings from Brasil...
Rewriting the problem sets
A = {-7, 4, 2, 14, 21, 34, 42}
B = {...; 2; 4; 6; 8; 10; 12; 14; 16; 18; 20; 22; 24; 26; 28; 30; 32; 34; 36; 38; 40; 42;...}
C = {...; -14; -7; 0; 7; 14; 21; 28; 35; 42; 49; 56; 63; 70; 77;...}
So, according to the statement, it is desired:
A ∩ B ∩ C - the intersection between the 3 sets, that is, which numbers are present simultaneously in the 3 sets....
Looking at the sets we conclude that
<h3>A ∩ B ∩ C = {14; 42}</h3>
