What are the possible values of x in -11x^2 + 2x = 10?

vlabodo [156]

-11x² + 2x = 10
-11x² + 2x - 10 = 10 - 10
-11x² + 2x - 10 = 0
x = -(2) +/- √((2)² - 4(-11)(-10))
 2(-11)
x = -2 +/- √(4 - 440)
 -22
x = -2 +/- √(-436)
 -22
x = -2 +/- 2i√(109)
 -22
x = -2 + 2i√(109) x = -2 - 2i√(109)
 -22 -22
x = ¹/₁₁ - ¹/₁₁i√(109) x = ¹/₁₁ + ¹/₁₁i√(109)

5. Find cos theta if sin theta= -12/13 and tan theta > 0. (6 points)

ziro4ka [17]

$\text{Given that,}\\\\\sin \theta = -\dfrac{12}{13}\\\\\implies \sin^2 \theta = \dfrac{144}{169}\\\\\implies 1- \cos^2 \theta = \dfrac{144}{169}\\\\\implies \cos^2 \theta = 1- \dfrac{144}{169}\\\\\implies \cos^2 \theta = \dfrac{25}{169}\\\\\implies \cos \theta = \pm \sqrt{\dfrac{25}{169}} = \pm \dfrac 5{13}\\\\\\\text{Since,}~ \tan \theta >0,\\\\\cos \theta =- \dfrac{5}{13}$
