2, but the exact answer is 7.4
Just about because the exact answer is 14.09670573 feet
X=60 how did you get that? could you show all the steps?
cos x - 0.5 = 0 ⇒ cos x = 0.5 ⇒ x = 2nπ ± π/3
Completing the square is advantageous in several situations:usually, it requires fewer steps than the quadratic formula, reducing the potential for error.it allows you to determine the exact value of the answer instead of a decimal approximation.it allows you to determine imaginary solutions.
x^(2) = 5x + 2 x^(2) - 5x - 2 = 0 This does NOT factor so apply the Quadratic Eq;n x = { - - 5 +/- sqrt[(-5)^2 - 4(1)(-2) }} / 2(1) x = { 5 +/- sqrt[25 + 8]} / 2 x = { 5 +/- sqrt(33)} / 2 x= { 5 +/- 5.7445... } / 2 x = 10.7445... / 2 = 5.37228.... & x = -0.7445626... / 2 = -0.37228...

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.
