For this case we must follow the steps below:
step 1:
We place each of the given points on a coordinate axis
Step 2:
We join the AC points (represented by the orange line)
We join the BD points (represented by the blue line)
It is observed that the resulting figure after placing the 4 points on a coordinate axis, turns out to be a rhombus.
In addition, the blue and orange lines turn out to be perpendicular, that is, they have an angle of 90 degrees between them. This can be verified by finding the slopes of each of the two straight lines (blue and orange), which must be opposite reciprocal, that is, they comply: 
In this case, the slope of the orange line is
and that of the blue line is 
Then
, it is verified that they are perpendicular.
Thus, the conclusion is that ABCD is a rhombus and AC is perpendicular to BD.

Option D
Answer:
A
Step-by-step explanation:
Answer:
Percent change from 15 to 18.
You need to divide the numbers, but which one goes on top?
You know the number increases from 15 to 18, so the percentage must be greater than 100%.
The only way to get a number greater than 100% is to put the larger number on top.
Therefore, the answer is 18/15 = 1.2
Multiply by 100 to get a %
1.2 * 100 = 120%
2. Calculate percentage change
from V1 = 5 to V2 = 8
ans= 60%
overall answer gain of 15 yards and 18 yards
Answer:
quad 3
Step-by-step explanation:
Subtract multiples of 360
944 -360
584
584 -360
224
0-90 is in quad 1
91 -180 is in quad 2
181 - 270 is in quad 3
Answer:
x=2
Step-by-step explanation:
F(x) = 2x^2 - 8x +8
Axis of symmetry lies at the x coordinate of vertex
To find x coordinate of vertex use formula

from the given f(x) , a= 2 and b = -8
Plug in all the values


x=2
So the axis of symmetry at x=2
