Part a
given that p=(5,4), q=(7,3), r=(8,6), and s=(4,1), find the component form of the vector pq+4rs.
a.(18,19)
,-6)
,-21)
,-19)

part b
use the information from part a to find the magnitude of the vector pq+4rs.
a. 2sqrt10
b. 7sqrt13
c. sqrt35
d. 637

Step-by-step explanation:

The given points have coordinates; P=(5,4), Q=(7,3), R=(8,6), and S=(4,1).

The correct answer is C

The magnitude is given by:

The correct answer is B

the answer is c.

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
