The exact solutions are [5 ± sqrt(33)]/2. The approx values are -0.3723 and 5.3723
2, but the exact answer is 7.4
X=60 how did you get that? could you show all the steps?
Just about because the exact answer is 14.09670573 feet
cos x - 0.5 = 0 ⇒ cos x = 0.5 ⇒ x = 2nπ ± π/3

5 x 5 = 25 25/7.4 = about 3.3783 (As an exact fraction, it is 125/37)
cos x - 0.5 = 0 ⇒ cos x = 0.5 ⇒ x = 2nπ ± π/3
1.9
The exact solutions are x = 0.5*{-3 +/- sqrt[32 - 4*1*(-5)]} = 0.5*{-3 +/- sqrt[32 + 20]} = 0.5*{-3 +/- sqrt[29]} = - 3/2 - sqrt(29)/2 and - 3/2 + sqrt(29)/2 The approx equivalent solutions are -4.1926 and 1.1926
No, alkaline and acidic are exact opposites.
