Answer:

A = 121π in²

Step-by-step explanation:

The circumference (C) of a circle is

C = 2πr ( r is the radius )

Here C = 22π , that is

2πr = 22π ( divide both sides by 2π )

r = \frac{22\pi }{2\pi } = 11

The area (A) of a circle is

A = πr² = π × 11² = 121π in²

1) The x-axis represents the energy (E), in joules. The y-axis represents the amplitude (x), in milimeters.

2) The curve depicts an <em>monotonous decrecent</em> rate of change.

3) The amplitude is directly proportional to the root square of the energy.

<h3>How to analyze a graph relationship between two variables</h3>

In this question we have a relationship between two variables, in which we must apply principles of <em>functional</em> analysis to respond three questions presented in the statement.

Now we proceed to answer the three questions below:

  1. <em>What is on the x-axis? The y-axis?</em> R/ The x-axis represents the energy (E), in joules. The y-axis represents the amplitude (x), in milimeters.
  2. <em>How would you describe the rate of change of the line?</em> R/ The curve depicts an <em>monotonous decrecent</em> rate of change, that is, the slope converges to zero when the energy tends to infinite.
  3. <em>What does this tell you about the relationship between amplitude and energy?</em> R/ The curve show a strong similarity with a function of the form x = A\cdot \sqrt{E}. Hence, the amplitude is directly proportional to the root square of the energy.

Jose' traveled from his home in Ocala to Gainesville. Gainesville is 37 miles
Alja [10]

Answer:

The integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.

Step-by-step explanation:

The direction is represented by the sign that accompanies the distance, since Jose is returning from Gainesville, then the direction must represented by a minus sign (-), since he is travelling southwards. The distance is the magnitude of the length covered by Jose during his return. Hence, distance is represented by the natural number 37.

Finally, the integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.
