Answer:
9 m
Step-by-step explanation:
A 30°-60°-90° triangle is a "special" right triangle. It is worthwhile to remember that the ratio of side lengths is ...
1 : √3 : 2
The shortest side (h) is 1/2 the length of the longest side (18 m).
h = 9 m
_____
In case you want to exercise your trigonometry, you recognize that the sides of interest in the question are the side opposite the angle, and the hypotenuse. The appropriate relation is ...
Sin = Opposite/Hypotenuse . . . . . . . from SOH CAH TOA
sin(30°) = h/(18 m)
h = (18 m)sin(30°) = (18 m)(1/2)
h = 9 m

Answer:
The second graph.
Step-by-step explanation:
The first piece of the piecewise function is g(x) = -2x, and it is on the part of the domain defined by x < -2. This means that the point at -2 will not be filled in, since it is strictly less than and not less than or equal to. It also means that the graph will be a line with a slope of -2 from this point backward; this means going backward, the graph will go up two and backward 1.
The second piece of the piecewise function is g(x) = -x². This will be an upside-down parabola (u-shaped graph) that passes through (-1, 1), (0, 0) and (1, -1). It is for the piece of the domain including -2 and going up to but not including 1; this means the left endpoint will be filled in and the right will not.
The third piece of the piecewise function is g(x) = x. This is a straight line with a slope of 1, meaning it goes up 1 and over 1. It is for the part of the domain including 1 and going to the right. This means the endpoint will be filled in.
