Answer:
4x^2 - 1 = 0
Step-by-step explanation:
x = 1/2, x = -1/2
2x = 1, 2x = - 1
2x - 1 = 0, 2x + 1 = 0
( 2x - 1 )( 2x + 1 ) = 0
4x^2 - 1 = 0
9 students. Write a fraction equality like: 3/8 = s/24. (S represents students) to get 8 equal to 24, you have to multiply it by 3, so you multiply the fraction 3/8 by 3 on the numerator and the denominator to get: 9/24
3.5 each is what they should get.
Answer:
B
Step-by-step explanation:
For cartesian to polar transformation,
x = rcosA , y = rsinA.
Put in the values in the given equation. And (cosA)^2 - (sinA)^2 = cos(2A)
