Answer:
B.) Orthogonal
Step-by-step explanation:
Two vectors u and v whose dot product is u·v=0 are said to be orthogonal
u = <6, -2>, v = <2, 6>
u·v = u1*v1 + u2*v2
6*2 + -2 * 6
=12 -12
=0
Answer:
-1/3
Step-by-step explanation:
By using this equation:
, we can find the slope of the line. We get -1/3.
Answer:
The ratio is
.
Step-by-step explanation:
The ratio of the perimeters of Quad ABCD to Quad WXYZ = 
But considering sides AB and WX,
representative factor for both figures = 
So that;
WX = 12
XY = 1.5 x 6 = 9
YZ = 1.5 x 7 = 10.5
WZ = 1.5 x 7 = 10.5
Thus,
perimeter of Quad ABCD = 6 + 7 + 7 + 8
= 28
perimeter of Quad WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of Quad ABCD to Quad WXYZ = 
= 
Answer:
x = 40
Step-by-step explanation:
180 = 100 + x +x
180-100= 2x
80 = 2x
x = 40
Answer:
-0.25
Step-by-step explanation:
need to find the halfway point (average) between -0.75 and 0.25 (same as 1/4)
To get average, add them together: (-0.75) + (0.25) = -0.5, divide by two since there are two numbers, to get average -0.25
