Which of the following theories proposes that people prefer to feel they have control over their actions, so anything that makes a previously enjoyed task feel more like an obligation than a freely chosen activity will undermine motivation?

a) two-factor theory
b) goal setting theory
c) motivation-hygiene theory
d) self-serving theory
e) self-determination theory

E) self-determination theory

Explanation:

Theory of self-determination (SDT) is a broad structure for human motivation and personality research.

It articulates a meta-theory for defining inspirational research, a structured theory defining inherent and diverse motivational sources, as well as a description of both the respective positions of intrinsic and kinds of extrinsic motivation in cognitive and social progress and individual differences.

More specifically, the SDT recommendations often concentrate on how cultural and social influences, in relation to their well-being and the quality of their success, promote or undermine the sense of will and initiative of people.

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.

the answer is: guns or butter
