Read the excerpt from Roll of Thunder, Hear My Cry. As I followed, Jeremy touched my arm timidly. "C-Cassie, you didn't have to do that. That—that ole Lillian Jean, she ain't worth it."

I stared at Jeremy, trying to understand him. But he shied away from me and ran down the road after his sister.

PLS HURRY
Which statement best describes and explains a character's actions?

Cassie challenges Jeremy because she does not value his opinion.
Cassie questions Jeremy’s actions because they do not make sense to her.
Jeremy comforts Cassie because he knows she is afraid of Lillian Jean.
Jeremy assists Cassie because he sees her efforts to support Lillian Jean.

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

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

its a trick question
