Rayon whiteness is an important factor for scientists dealing in fabric quality. whiteness is affected by pulp quality and other processing variables. some of the variables include acid bath temperature, ◦c; cascade acid concentration, %; water temperature, ◦c; sulfide concentration, %; amount of chlorine bleach, lb/min; and blanket finish temperature, ◦c. a set of data from rayon specimens is given here. data provided in spreadsheet.

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

step-by-step explanation:

i think its about 8
