Answer:
96 sq. cm.
Step-by-step explanation:
A "kite" has 2 diagonals, which are the "width" and "height" of the kite.
Using diagonals, the area of a kite is given by
Where
A is the area
p,q are the width and height, respectively
From the problem given, p is 12 and q is 16, so the area is:
Thus, the area is 96 sq. cm
Answer:
A
Step-by-step explanation:
A, B, C, and D, are all functions. the " { " is saying that those functions can are different at different points. For A the function is when
and then
when
. At the point
you can see that the function on the graph is going in two different directions but it stops at
.
Based on the graph you can see that the line on the left has a slope of -1 and if it kept going it would cross the y-axis at , therefore the equation for the first line is
when
The second line on the right side has a slope of 1 and crosses the y-axis at so the equation for that line is
when
.
The only answer that matches these requirements is A
