Principal Simons purchases boxes of pens for her school at an online store. The store charges her the same amount for each box of pens plus a flat shipping fee for any number of boxes she purchases Selected numbers of boxes and the corresponding total cost including the shipping fee for that number of boxes are shown in the table Lett be a function that models the total cost including the shipping fee in dollars, to purchase p boxes of pens Based on the values in the table, which of the following best defines the function t? A. t (p) =p+4.08
B. t (p) =3.6p
C. t(p) =3.6p+2.4
D. t(p) =4.08p

step-by-step explanation:

f

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

well what did you do it matters what you did : )
