Answer:C
Step-by-step explanation:
Answer:
2j²/5
Step-by-step explanation:
We know that j has to be squared so j², and to find 2/5's of that number we need to multiply it by 2/5.
j²×(2/5)
Now to simplify it we can multiply the j² to the numerator.
2j²/5
There are NO choices.
I know for TWO linear equations to have a unique solution they CANNOT be parallel.
Answer:
Option D. tan 225° is the correct answer.
Step-by-step explanation:
As we know 
Given in the question angle A = 112.5°
Hence the formula becomes as

Therefore its a formula of tan2(112.5) = tan 225°
Option D. is the correct answer.
A= π r^2, and we don't know r, so we'll have to use r = √C/π.
√C is and infinite number, and the square root of
π is an infinite number, so this problem is impossible.
