One day, the state fair total attendance was 126,945. round 126,945 to the nearest hundred thousand, nearest ten thousand, and nearest thousand. which of these rounded amounts is closest to the actual attendance

100000

130000

127000

127000

Step-by-step explanation:

126945 is read as One hundred twenty six thousand and nine hundred forty five

The closest hundred thousand would be 100000 i.e., One Hundred thousand

The closest ten thousand would be 130000 i.e., One hundred and thirty thousand.

The closest thousand would be 127000 i.e., One hundred and twenty seven thousand.

127000 is the closest to the actual attendance .

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 answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
