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

raketka [301]

Answer:

960

Step-by-step explanation:

3/8*total number of animals = 600

total number of animals = 8/3 * 600 = 1600

number of animals fed = 40/100 * 1600 = 640

animals still to be fed = 1600 - 640 = 960
