Step-by-step explanation:
A) The graph is three horizontal line segments.
Since the domain expressions all have ≤ on the left end of the interval and < on the right end, there will be a closed dot at the left end of each graph segment and an open dot at the right end.
The first segment is at y = -5 between x = -5 and x = -1.
The second segment is at y = -1 between x = -1 and x = 2.
The third segment is at y = 2 between x = 2 and x = 5.
See the first attachment for a graph.

B) You are given the graph for the middle segment, so you only need to graph the horizontal lines for the other two.
The first segment is a horizontal line at y = 1, extending to the left from x = -1.
The last segment is a horizontal line at y = 4, extending to the right from x = 2.
The segments of the graph connect with each other, so there is no need to indicate any discontinuities using closed/open circles.

<span>We are working with a circle, which means that our rubber edging needs to be as long as the circumference of the circle. Circumference (C) is calculated by multiplying the diameter (d) times pi (Ď€). [C=dĎ€] And the diameter is simply the radius (r) multiplied by two. [d=2r] We can calculate the radius by dividing 12.5 by pi and then taking the square root of the quotient.[r=âš(12.5/Ď€)] In this case, the radius is equal to 1.99. We then double the radius and multiply by pi.[C=2(1.99)Ď€] When we do, we find that the circumference is 12.5. Therefore, Carlos will need to buy 12.5 feet of rubber edging.</span>
From the figure we notice that the triangle is an isosceles one. This means that the angles RTS and RST are the same. Hence:
To find the remaining angle we need to use the fact that the sum of the interior angles of any triangle is 180, then:
Plugging the values we know and solving for TRS we have:
Therefore, the angle TRS is 38°.
