Hello :
by moivre theorem :
[2(cos15*+isin15*)]^3 = 2^3(cos(3×45*)+isin(3×45*))
=8 (cos45*+isin45*)
= 8 ( √2/2 +i √2/2)
= 4√2 + 4√2 i ..... ( <span>in standard form a+bi)
</span>a = b = 4√2
Step-by-step explanation:
Demand for Goods and Services. Economists use the term demand to refer to the amount of some good or service consumers are willing and able to purchase at each price. The total number of units purchased at that price is called the quantity demanded.
Rayshawn will need 72 more bags of mulch.
126 minus 18
108 divided by 3
36 times 2
equals 72
Answer:
the value of x is (-2) and y is (-5)
The length of the flagpole is x - 5 yards
<h3>How to determine the length of the flagpole?</h3>
The area of the flagpole is given as:
Area = x^2 - 10x + 25
Expand the expression
Area = x^2 - 5x -5x + 25
Factorize the expression
Area = (x - 5)(x - 5)
Express as squares
Area =(x - 5)^2
The area of a square is
Area = Length^2
So, we have:
Length = x - 5
Hence, the length of the flagpole is x - 5 yards
