Please help The art museum is giving away tickets to the Greco exhibit. Today, the museum expects to give away 150 percent of the 800 tickets that it gave away yesterday. Martin is trying to figure out how many tickets the museum will give away today. His work is shown below.

StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction

100 times 8 = 800

150 divided by 8 = 18.75

What mistake did Martin make?
Martin should have multiplied 150 by 8.
Martin should have divided 100 by 8.
Martin should have added 150 and 800.
Martin should have multiplied 150 and 800.

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

you would need to know all the numbers that are on there

step-by-step explanation:

answer: no, but if it does it's a obvious pattern.
