Answer:

See below.

Step-by-step explanation:

Positive association is when the line has a positive slope, and the line progresses upwards.

E.g. When a car is traveling, as time progresses, the distance traveled increases.

Negative association is when the line has a negative slope, and the line declines.

E.g. When a car is traveling, as time progresses, the amount of gasoline decreases.

No association is when there is no slope between points, nor is there a line.

Find the area of a regular pentagon with an apothem of 11 units. *
docker41 [41]

Answer:

<h2>440 square units</h2>

Step-by-step explanation:

We can find half of a side of the pentagon with the expression

tan(36\°)=\frac{s_{half} }{11}

Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.

s_{half} \approx 8

Therefore, half of a side is 8 units long, which means each side measures 16 units.

Now, the area of a penthagon is defined by

A=\frac{p \times a}{2}

Where p is the perimeter and a is the apothem. Where the perimeter is the sum of all sides, which is 80 units.

A= \frac{80 \times 11}{2} =440 \ u^{2}

Therefore, the right answer is the second choice.
