Answer:
Correct answer: B
Step-by-step explanation:
Syntax: in piecewise functions such as the one attached, the "if:" section shows the domain, or x-axis values which that function pertains to.
In the graph, you can see that the graph is defined for
(not-including 1 because there is an open hole there, indicating it is not part of the domain), and
.
Now that we know the domain, we can attach it to the graphs that lie on those domains.
We see that the leftmost line appears to have a positive slope and a negative y-intercept, and that the second line should have a positive y-intercept and a negative slope.
At this point, you can just start crossing off answers that don't meet this criteria.

Answer: X=2 and y=3
Step-by-step explanation: 2x2=4 and 3x3=9 and 9+4=13
To find h, divide the area by the base:
h = 2442 / 12 = 203.5 km.
The simplified answer would be 9120ax
