An actor is hired to appear in a series of commercials promoting a new laptop computer. The actor's last two movies, though, have failed at the box office, and he is not very popular at the moment. This means that the actor may NOT serve as the optimal in the commercials.

Unconditioned stimulus.

Explanation:

Unconditioned stimulus is one that results in a reflexive response. The response is natural, unconditional, and automatic. For example if one smells a food he likes (unconditioned stimulus) the person' s response is to become hungry.

In contrast conditioned stimulus is learners and voluntary.

The actor has had two of his movies fail at the box office so his appearance on the commercial will produce a unconditioned response from the audience that is not favorable. He will have to wait till there is a good impression about him.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
