make v the subject of the formula S = \(\sqrt{\frac{6}{v} - \frac{w}{2}}\)
v = \(\frac{12}{2s^2}\)
v = \(\frac{12}{2s+ w}\)
v = \(\frac{12}{2s^2 + w}\)
v = \(\frac{12}{2s^2}\) + w
Explanation
S = \(\sqrt{\frac{6}{v} - \frac{w}{2}}\)
S = \(\frac{12 - vw}{2v}\)
2vs\(^2\) = 12 - vw
v(2s\(^2\) + w) = 12
v = \(\frac{12}{2s^2 + w}\)
S = \(\frac{12 - vw}{2v}\)
2vs\(^2\) = 12 - vw
v(2s\(^2\) + w) = 12
v = \(\frac{12}{2s^2 + w}\)
