Elaine is reading a fairy tale to her newborn baby as she feeds the baby its bottle. although the milk in the bottle is gone, the baby continues to suck on the nipple as the mother continues to read the baby the story. this is an example of what type of conditioning?

Classical conditioning

Explanation:

There are three main types of conditioning: classical, operant and observational.

In a classical conditioning, people associate events and stimuli that frequently happen together and they learn to anticipate these events. The most famous example of classical conditioning is Ivan Pavlov's experiment with his dog.

Elaine's baby is still sucking on the nipple even if the bottle is empty because he/she associates the bottle with feeding and the mother's presence.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7

this doesn't support enough information to answer the question.
