<h3>Answer: C) 180 or 0</h3>
====================================
Work Shown:
Let y = sin(x). Solve for y then solve for x
-4+6*sin(x) = -4+4*sin(x)
-4+6*y = -4+4*y ... replace sin(x) with y
6y-4y = -4+4
2y = 0
y = 0/2
y = 0
sin(x) = 0 ... plug in y = sin(x)
x = arcsin(0) or x = 180-arcsin(0)
x = 0 or x = 180
We have two solutions here since
sin(0) = 0 and sin(180) = 0
The solutions x = 0 and x = 180 fit in the interval 
So do 50 times 12 is 600. So all you have to do is divide 144 by 600 which is .24 so she already swam 24%
A football team wants to by a football. The football costs $51. There are 11 members of the team. How much will each of the team members contribute to be able to purchase the football if they had $29 already.
Solution: Let the amount each team member contributes be x, then
11x + 29 ≥ 51
11x ≥ 51 - 29
11x ≥ 22
x ≥ 22/11
x ≥ 2
I.e. each team member must contribute at least $2 for them to be able to buy the football.
