Gradually, Lynette stopped inviting me over after school.
One day, on my way into the girls' bathroom, I overheard
Lynette and Shelley Abrams discussing their after-school
plans at Dale's Ice Cream
"This afternoon is going to be so much fun," said Lynette.
"It's going to be you, me, and the rest of the 'Fab
Thirteens. Just remember, no twelve-year-olds."
I heard a foilet flush and scurried into an empty stall. Their
giggles felt like needles. I heard the sinks running and
knew they were tossing their locks in the mirror. This
couldn't be happening. But I was quickly getting the picture
that it was

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

555.99.

step-by-step explanation:

hope this

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

correct answer:

b.(19,-2)
