Answer:
C. -262.44
Step-by-step explanation:
-3.24, 9.72,-29.16, 87.48
-3.24*-3= 9.72, 9.72*-3= -29.16, -29.16*-3= 87.48
the rule for this sequence is multiplying by -3
87.48*-3= -262.44

<span>Neon is heavier than helium and does not react with other elements. This is because Neon is a noble gas and is very stable because its outer electrons are filled.</span>
Answer:
Option (1)
Step-by-step explanation:
Coordinates of the vertices of a quadrilateral WXYZ drawn in the figure are,
W(-1, 4), X(2, 2), Y(0, -1), Z(-3, 1)
Length of a segment having ends as
and
is represented by,
d = 
Length of WX = 
= 
= 
Length of XY = 
= 
Length of YZ = 
= 
Length of ZW = 
= 
Slope of side WX (
) = 
= 
= 
Slope of side XY (
) = 
= 
By the property of perpendicular lines,


therefore, WX and XY are perpendicular.
Slope of YZ (
) =

Therefore, XY ⊥ YZ
Similarly, we can prove YZ ⊥ ZW.
Therefore, quadrilateral WXYZ is a SQUARE.
Option (1) will be the answer.
