Solve the equation or formula for the indicated variable.

R = ts2 + 3 for s

a) s= (square root of R-3) /t
b) s= square root of R-3/t
c) s= (square root of R)-3/t
d) s= square root of R/t -3

c) s= (square root of R)-3/t

To solve the equation R = ts^2 + 3 for s, we need to isolate s on one side of the equation. Let's go step-by-step:

1. Start with the equation: R = ts^2 + 3.
2. Subtract 3 from both sides of the equation to get: R - 3 = ts^2.
3. Divide both sides of the equation by t: (R - 3) / t = s^2.
4. Take the square root of both sides of the equation: √((R - 3) / t) = s.

Therefore, the correct answer is:
a) s = √((R - 3) / t).
