In pure competition, producers compete exclusively on the basis of a-sell identical items. b-advertise heavily to promote their good. c-product the unique features of their good. d-focus on maintaining a positive image. its ( a ),

The answer is "A-sell identical items."

Pure competition is a term that portrays a market that has an expansive scope of contenders who are offering similar items. Usually alluded to as flawless rivalry. Here are a few attributes that characterize pure competition:

In a perfect purely competitive market, the items being sold would be indistinguishable, which expels the alternative of one merchant offering something other than what's expected or superior to another dealer.  

Since there are such a significant number of rivals in the market offering a similar item at a similar value, one contender doesn't have an edge over the others. Basically, every one of the merchants are equivalent.  

New organizations can without much of a stretch enter the market.  

The cost of items is resolved exclusively by what customers will pay.

explanation:

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
