Please answer, explanation NEEDED
The magnitude of vector λa is 5. Find the value of λ, if: a = (−6, 8);

the answer is b.)

< 1=< 2

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

5 feet of chain cost $9

so the answer is 1.80
