Answer:

P(t)= 50.3^-0,09 (1≤t≤6)

"t" should be measuread in decades. t=1means 1980.

Explanation:

Middle class income is a term used to describe citizens who are on the rise economically and do not represent the country's economic elite, but neither do they represent the most needy and marginalized population. This class is characterized by citizens who earn between $ 50,000 and $ 500,000 a year.

In American society, the middle-income class has been decreasing more and more each year. This reduction has been measured since 1970 and the way to calculate the percentage of families with annual income within the median income is through the formula: P (t) = 50.3 ^ -0.09 (1≤t≤6).

"t" should be measuread in decades. t = 1means 1980.

Wittaler [7]

Answer: c) Substage 3: Secondary circular reactions

Explanation:

Piaget's theory posits that children go through four different stages of cognitive development. Their mental development includes language, morals, memory and the like.

The sensorimotor stage is the earliest in Piaget's theory of cognitive development and is described as a period of tremendous growth and change.

It is divided into substages, the third of which is called SECONDARY CIRCULAR REACTIONS where the child becomes more focused on the outside world and begins to repeat activities to derive joy from them such as picking up a toy to put in their mouth.
