Answer:
B
Step-by-step explanation:
slope of Z = 0.24
W= -0.0625
We desire to discover the value of ||v+w||
if v=5i-7j and w=3i+2j
|r| =../r.+..r .....√...1....2
if r = r(1)i +r(2)j
We first find the value of
v+ w by adding v(1) +w(1) = 5+3 = 8 and by adding v(2) +w(2) = -7+2 = -5
so v+w = 8i -5j
and
|v+w| = √8²+(-5)²
=√64 + 25
=√89
= 9.43398113
