Answer:
there are many differences but I am not allowed to tell you
Step-by-step explanation:
For the algebraic expressions to have the same value regardless of the value of the variable, let the variable appear in both the numerator and the denominator. Example,
78x / 13x = 6
We can cancel the x's from both the numerator and denominator and the expression becomes, 6 = 6.
Answer:
![\theta=60\degree](https://tex.z-dn.net/?f=%5Ctheta%3D60%5Cdegree)
Or
![\theta=\frac{\pi}{3}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B%5Cpi%7D%7B3%7D)
Step-by-step explanation:
We want to find the angle which forms a y-coordinate of ![\frac{\sqrt{3} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D)
on the unit circle.
The y-coordinate on the unit circle is given by
.
This implies that ![\sin(\theta)=\frac{\sqrt{3} }{2}](https://tex.z-dn.net/?f=%5Csin%28%5Ctheta%29%3D%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D)
![\Rightarrow \theta=\sin^{-1}(\frac{\sqrt{3} }{2})](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%3D%5Csin%5E%7B-1%7D%28%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%29)
![\Rightarrow \theta=\sin^{-1}(\frac{\sqrt{3} }{2})](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%3D%5Csin%5E%7B-1%7D%28%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B2%7D%29)
![\Rightarrow \theta=60\degree](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%3D60%5Cdegree)
Or
![\theta=\frac{\pi}{3}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B%5Cpi%7D%7B3%7D)
x +1 x^2 +5x +4 x +1 (x +1)(x +4)
---------------- / ---------------------- = ----------------- / ----------------------- =
x^2 +x -6 x +4 (x +3)(x -2) x +4
x +1 1 1
= ---------------- * ----------- = ------------------
(x +3)(x -2) ( x +1) (x +3)(x -2)
so the second choice is right sure
Answer:
It should be the last one
