Discussion: Relationships Between Functions
Homes can come in many different forms, such as apartments, townhouses, and duplexes. While each is different from the other, they all contain some common characteristics.
What is another example of things that are different, but still share some common traits?
Explain your reasoning.

Phones, tablets, laptops

Step-by-step explanation:

They all connect to the internet in order to fetch data for the client user, and display images onto your screen. They all function about the same way, but are entirely different in their own aspects.

Hope this helps :)

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
