Answer:
;
is even and greater than zero.
The absolute value function 
Step-by-step explanation:
The power function;
;
is even and greater than zero, is symmetric with respect to the positive y-axis.
As
and as 
The absolute value function
also has the same end behavior.
The remaining functions in the options provided do not exhibit this end behavior.
See graph in attachment.
348 in. 2
2·(8·9+6·9+6·8)=348
4c+5.6d=1360
Let
Children (c)=x
Adults (d)=284-x
4x+5.6 (284-x)=1360
Solve for x
4x+1590.4-5.6x=1360
4x-5.6x=1360-1590.4
-1.6x=-230.4
X=230.4÷1.6
X=144 children
284−144=140 adults
No, it never can be a right triangle.
First, all the angles of an equilateral triangle is 60 degrees because all angles are the same and all the angles add up to 180:
180/3 = 60.
So if it is a right angle it needs one angle 90 degrees which an equilateral triangle can't have,
It is equivalent too 5.3 and 5.30
