Amusic video website received 5,000 comments on a new song they released. after the artist performed the song on television, the number of comments increased by 30% the next day. how many new comments were on the website at the end of the next day?

new comments will appear on the website at the end of the next day

Step-by-step explanation:

Given the music video website receives comments on a new song they released.

Also, after the performance on television, the number of comments increased by %.

So, increased comments are % of

Now, the total number of comments by the end of the next day will be.

Comments on new song release Increased comments

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

the correct answer is 5 6 and 7
