8.2 Is the answer I believe!
We are given the functions

and

.
let's consider some pairs in the graph of both functions.
in

we have (-2, 4), (2, 4), (3, 9), (-5, 25)
in

we have (-2, -4), (2, -4), (3, -9), (-5, -25)
so for the same values of x, we have y's of equal value, but different sign.
This means that the functions are the reflections of each other with respect to the x-axis.
Answer: C <span>reflection over the x-axis</span>
Answer:

Step-by-step explanation:
Given that,
The base of a trapezoid, b = 21.6 m
Height of the trapezoid, h = 4.5 m
The tope of the trapezoid, a = 11.9 m
We need to find the area of a trapezoid. The formula for the area of a trapezoid can be given by :

Put all the values,

Hence, the area of a trapezoid is equal to
.
Answer:
0.085 m
Step-by-step explanation:
change in displ. = change in velocity ÷ change in time
so,
x = v ÷ t
= -1.7 m/s ÷ 20s
=0.085 m
