I don’t know I don’t have the smarts for that lol
Given:
To find:
The correct equivalent equation.
Solution:
We have,
Taking sin on both sides, we get
![[\because \sin (\sin^{-1}\theta )=\theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%20%28%5Csin%5E%7B-1%7D%5Ctheta%20%29%3D%5Ctheta%5D)
Interchanging the sides, we get
Therefore, the correct option is 4.
Answer:
Step-by-step explanation:
Given: 
To find: the correct option
Solution:
A binomial polynomial is a polynomial consisting of two terms.
A trinomial polynomial is a polynomial consisting of three terms.
On multiplying a binomial 
to itself, a perfect square trinomial 
is obtained.
Here, 
So, 
Here, 
is a binomial and it is multiplied to to get a perfect square trinomial
5/4 = 75/g....cross multiply because this is a proportion
5g = 300
g = 300/5
g = 60
so in 2nd semester, there were 75 students in art class and 60 students in gym class....for a total of 135 students.
1st semester....ratio was 2:7...added = 9
art : 2/9(135) = 270/9 = 30 <=== art class had 30
gym: 7/9(135) = 945/9 = 105 <=== gym class had 105
