The value of \(\sqrt{196}\) + \(\sqrt{0.0361}\) − \(\sqrt{7.29}\) is _____.
Pipe A can fill a tank in 18 hours, pipe B can fill the same tank in 28 hours and pipe C can fill the same tank in 11 hours. The time taken by them to fill the same tank if they operate together is:
10 \(\frac{247}{505}\) hours
7 \(\frac{247}{505}\) hours
11 \(\frac{247}{505}\) hours
5 \(\frac{247}{505}\) hours
If P = tanθ + secθ, then the value of tanθ is:
\(\frac{P^2+1}{P}\)
\(\frac{P^2-1}{P+1}\)
\(\frac{P^2+1}{2P}\)
\(\frac{P^2-1}{2P}\)
