Which of the following is the final step in bisecting a line segment? a. keeping the compass at the same width, place the compass on the other endpoint and swing b. arcs on either side so that they intersect the first two arcs created. c. mark the intersection points of the arcs, and draw a line through those two points. d. place the compass on one of the endpoints, and open the compass to a distance more than halfway across the segment. swing an arc on either side of the segment.

answer: c. mark the intersection points of the arcs, and draw a line through those two points.

step-by-step explanation:

to draw bisector of line segment. there are following steps:

1) draw circles from both the endpoints of the length segments taking them as center of circles.

2) mark the intersection points of the circles and use the straightedge to draw a line through the marked points .

thus, c is the right answer."mark the intersection points of the arcs, and draw a line through those two points."is the the final step in bisecting a line segment.

the last step in the construction is:

mark the intersection points of the arcs, and draw a line through those two points.

step-by-step explanation:

the steps of bisecting a line segment is as follows:

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

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
