Ahospital is considering changing its supplier of replacement joints. while surgeons make the final decision, the hospital's purchasing department is promoting kyocera because it manufactures one of the cheapest and most durable hip joints on the market. in terms of the buying center, the purchasing department is a(n): a) deciderb) influencerc) judged) usere) demand driver

B) influence

Explanation:

The purchasing department is responsible for researching products at suppliers, showing the budget to doctors / hospital executives and placing the purchase order. Thus, the purchasing department has an influencing role in the decision, but does not take the final word. The decision is up to the executives and doctors, who are the people who will use the replacement joints directly.

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.
