Find the inner product for (4,8). (6,-3) and state whether the vectors are perpendicular.
a. 0; no
c. 1; no
b. 0; yes
d.
1; yes

answer is b

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

the answer for the second equation is (4,0)
