2)
is a rhombus (a parallelogram with perpendicular diagonals is a rhombus)
3)
bisects
(diagonals of a rhombus bisect the angles from which they are drawn)
ANSWER and EXPLANATION
We want to order the functions from widest to narrowest:

To do this, we have to plot the graphs of the functions by using a table of values.
Let us find the values of the functions for values of x = -2, 0, 2
For the first function:

Hence, its table is:
For the second function:

Hence, its table is:
For the third function:

Hence, its table is:
Now, let us plot the graphs of the functions:
Therefore, from the graph, we see that the order of the functions from widest to narrowest is:
Let the total number of workers be x
Workers earning minimum wages=24
24=15% of x
Therefore,x*15/100=24
Taking 100 to RHS,x*15=24*100
x=2400/15
=160
0.078 rounded to the nearest hundredth is 0.08
