Successful product differentiation:
o is less important due to the growth of the internet.
o is prohibited if it restricts price competition and market access.
o of consumer goods is determined exclusively by price.
o can be based on either real or perceived differences in products.

The correct answer is letter "D": can be based on either real or perceived differences in products.

Explanation:

Product differentiation is a marketing tool companies used to distinguish their products or services from the competitions. Generally the more a product is differentiated and, thus, made unique, the more a company can charge for it. Product differentiation is usually subjective since its goal is to change customer's perception of the benefits of a product over another. Though sometimes the information provided can be objectively true.

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.
