Leviafan [203]

Answer:

There are two sources that serve as the foundation for conducting research on learning. The first source addresses characteristics of knowledge itself and the different ways in which we learn things. The second source focuses on what goes on in our minds and how that is theoretically represented.

Step-by-step explanation:

The investigations on the process of how we learn have led to two main sources:

- Acquisition of knowledge which involves assimilation or understanding, storage and retrieval

- The second source belongs to a modern learning cognitive psychology, neuroscience, and cognitive science theories on mental representation, which concerns about the build up of an internal symbol or cognitive representation to hypothetically figure out, external reality.

How do I solve this literal equation? <br> 15 points
kati45 [8]

Answer:

\pi = \frac{A}{2r^2 + 2rh}

Step-by-step explanation:

First, we need to isolate \pi by taking it common from both terms on the right:

A=2\pi r^2 + 2\pi rh\\A=\pi (2r^2 + 2rh)

Now, since we want \pi in terms of the other variables, we can divide the left hand side (A) by whatever is multiplied with \pi on the right hand side. Then we will have an expression for \pi. Shown below:

A=\pi (2r^2 + 2rh)\\\pi = \frac{A}{2r^2 + 2rh}

This is the xpression for \pi
