Answer:
The graph represents the heights of two climbers on a climbing wall over a 12-minute time period.
1 answer:
Both climbers rested on the wall at a constant height for 2 minutes.
<h3>How to determine the true statement?</h3>The illustrative graph that represents the climbers' movement is added as an attachment
From the attached graph, we have the following observation
- The line of Abby's movement is horizontal from x = 4 to x = 6
- The line of Brynn's movement is horizontal from x = 5 to x = 7
The difference between the endpoints of both horizontal line is
Difference = 6- 4 = 2
Difference = 7 - 5 = 2
This means that both Brynn and Abby stopped for 2 minutes
Hence, the true statement about is that (d) Both climbers rested on the wall at a constant height for 2 minutes.

Answer:
<h2>The height is 3.43 centimeters, approximately.</h2>Step-by-step explanation:
Notice that there are 16 pieces from the circle, which means each sector has an angle of
Where all sectors have equal area.
Now, the area of the whole circle is , if we use the formula of its area, we'll find the radius of the circle
Notice that each piece works as an isosceles triangle, because each side is the radius, that is, they have the same length. So far, we know the sides of the isosceles triangle and one internal angle.
To find the height of the one piece, we need to use trigonometric reasons, because the height divides a triangle in two equal right triangles.
Therefore, the height is 3.43 centimeters, approximately.
