Answer:k=1,k=-2,k=
Step-by-step explanation:
Given two vectors


Distance between them is given by

squaring both side



k=1

angle between u and v is 90 i.e. orthogonal

=0
2+k=0
k=-2

angle between u & v is 





=0
k=
Answer:
B) 1
Step-by-step explanation:
x+1/2(x-4)=1/2x+6(x-2)
x+1/2x-4/2=1/2x+6x-12
x+1/2x-1/2x-2=6x-12
x-2=6x-12
x-6x-2=-12
-5x-2=-12
-5x=-12+2
-5x=-10
5x=10
x=10/5
x=2
P = A(1+r)^x
where P is the population at time x
A is the initial population and r is the growth/decay rate. Growth will be +positive r number added to the 1. Where as decay subtracts r. So any answers that are > than 1 which is answers A and B.
