Answer:
approximately 7 days
Step-by-step explanation:
20 ÷ 3 = 6.6 repeating, round up to 7 days
When it's side length(L) would be √2
Yes this is correct because that angle in is with the other angles to
If you have some knowledge of complex numbers: This follows pretty much immediately from Euler's formula and DeMoivre's theorem,
(Euler)
(DeMoivre)
so that is the imaginary part of the expanded left hand side.
If that's unfamiliar to you, you can make use of several identities to expand :
(double angle sine)
(double angle sine and cosine)
(Pythagorean)
Answer:
Sometimes true
Step-by-step explanation:
There is only one x value that satisfies the equation.
4x + 1 = 3
4x = 2
x = 1/2
