In the equation below assume U and A are know.
Rearrange the equation so that you would solve for R in terms of the Greek letter sigma)
U = R − 1 2 A σ 2
A. R = U − 1 2 A σ 2
B. R = 1 2 A σ 2 U
C. R = U 1 2 A σ 2

Answer:

[tex]R = U + {1}{2}A\sigma^2[/tex]

Explanation:

Given

[tex]U = R - \frac{1}{2}A\sigma^2[/tex]

Required

Solve for R

We have:

[tex]U = R - {1}{2}A\sigma^2[/tex]

Add [tex]{1}{2}A\sigma^2[/tex] to both sides

[tex]U + {1}{2}A\sigma^2 = R - {1}{2}A\sigma^2 + {1}{2}A\sigma^2[/tex]

Evaluate like terms

[tex]U + {1}{2}A\sigma^2 = R[/tex]

Hence:

[tex]R = U + {1}{2}A\sigma^2[/tex]
