Find sec theta if theta is in quadrant 4 and sin theta= -1/5

lara31 [8.8K]

Answer:

$\frac{5}{2\sqrt{6} }$

Step-by-step explanation:

Since Θ is in fourth quadrant then cosΘ > 0, as is secΘ

Given

sinΘ = - $\frac{1}{5}$ , then

cosΘ = $\sqrt{1-(-1/5)^2}$

= $\sqrt{1-\frac{1}{25} }$ = $\sqrt{\frac{24}{25} }$ = $\frac{2\sqrt{6} }{5}$

Hence

secΘ = $\frac{1}{\frac{2\sqrt{6} }{5} }$ = $\frac{5}{2\sqrt{6} }$

Need help with this plz

Answer:

$x = \frac{ - 24 \pm \sqrt{ - 288} }{4} \\ = \frac{ - 24 \pm \sqrt{ ( - 1) {(12)}^{2} (2)} }{4} \\ = \frac{ - 24 \pm \sqrt{ - 1} \sqrt{ {12}^{2} } \sqrt{2} }{4} \\ = \frac{ - 24 \pm i 12\sqrt{2} }{4} \\ =-\frac{24}{4}\pm \frac{i12\sqrt{2}}{4}\\= - 6 \pm \: i3 \sqrt{2}$
