8 Ounces of shampoo for $0.89
Answer:
Step-by-step explanation:
y=(1/2)x+cos x
dy/dx=1/2-sin x
dy/dx=0,gives
1/2 -sin x=0
sin x=1/2=sin (π/6),sin (π-π/6)=sinπ/6,sin 5π/6=sin (2nπ+π/6),sin(2nπ+5π/6),n∈ I
d^2y/dx^2=-cos x>0 at x=π/6 and -2π+π/6
or at x=π/6,-11 π/6
2(2x-6)=28
4x-12=28
4x=28-12
4x=16
4x÷4=16÷4
X=4
You must divide both 4x and 16 by 4 because you're trying to isolate X and find what X is. I hope I helped.
