A real number
ok so
any even power is i^(2n) where n is a whole number
if n=1
i^2=(√-1)^2=-1
if i^3, then it is equal to (i^2)(i)=(-1)(i)=-i
if i^4, then it is equal to (i^2)(i^2)=(-1)(-1)=1
therefor
i^1=i
i^2=-1
i^3=-i
i^4=1
then it repeats
look at the odd powers
i and -i
they are complex
therefor
if i is raised to an odd power, it cannot be simplified to be a real number
Answer:
$5.04
Step-by-step explanation:
4.5 x 1.12=5.04
We can first look into the properties of parallelogram,you can also take reference from the figure above:
-Opposite sides are parallel and are congruent.
-Opposite angles are congruent.
-The diagonals bisect each other.
We can then look into the answer:
A.Opposite angles are congurent.
-This is an correct statement.
B.Diagonals are congruent.
-This is incorrect,although they bisect each other,they do not have the same length.
C.The diagonals are peroendicular to each other.
-This is incorrect as well,not every parallelogram has the angle of 90° in the place where the diagonals bisect each others.
D.The area is equal to the product of two adjacent side-this is not true,to find the area,it have to be base×height.
Therefore the answer is A.
Hope it helps!
