The answer is: Direct variation.

The explanation for this problem is shown below:

1. In direct variation, when a quantity x varies directly as another quantity y, the value of the quantity x increases when y increases, and decreases when y decreases.

2. Based on this information, let's see the expression given in the problem:

A=r^{2}

3. As you can see, if you give values to r^{2}, the value of A will have a direct variation. When r^{2} increases, A increases, and when it decreases A decreases.

Answer : Direct Variation

Question :

Identify the variation as direct, inverse, joint or combined. A = \pi r^2

We know direct variation is y = kx

Where k is the constant of proportionality

When value of x increases then y also increases. when x value decreases then y value decreases.

The value of y depends on value of x It means y is directly proportional to x.

Hence A = \pi r^2 is a direct variation.

Answer:

y = sin(x- pi/2)

Step-by-step explanation:

Please see the attached image to see your graphs.

By simple inspection we can see that the sine is shifted pi/2 to the right.

We know this because sines are periodic functions with a period T = 2*pi

We can also see that the maximum point of the graph (y = 1) got shifted by a fourth of the period.

And finally, since we want to shift the graph to the right, we need to substract from the argument of the sine term.
