Help! 10pts!! A landscape plan includes a rectangular flower bed that is surrounded the wood plans In the drawing, the
rectangular flower bed is in by 12 in. The length and width of the actual flower bed will be 26 times are
than the length and width in the drawing,
(a) What is the perimeter of the drawing? Show all calculations that lead to the answer and include units
(b) What is the perimeter of the actual flower bed? Show all calculations that lead to the answer and
include units
(c) What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 289 Write
the final answer in a sentence and show supporting calculations to arrive at the answer

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
