Answer:
A)
Step-by-step explanation:
uv = u1v1 + u2v2 = (1/3)*18 + 4*(-3/2) = 6 - 6 = 0
Because uv=0, these 2 vectors are orthogonal.
Answer:
.
Step-by-step explanation:
Given the zeroes of the polynomial are
a=-i . and b=3i
The recquired polynomial is 
On substituting the values of a and b we get


. (∵
)
Point Form:
(2, 4), (1, 1)
Equation Form:
x = 2, y = 4
x = 1, y = 1
