Can an angle that has a supplement also h ave a complement; always sometimes or never

Romashka [77]

Sometimes
for example a 30 degree angle has a 60 degree angle as its complement and a 150 degree angle as its supplement.

if you choose a 90 degree angle it can only have a supplement
if you choose a 180 degree angle it can't have either

hope this helps

Show that y2+ x-3 =0 is an implicit solution to dy/dx =-1/ (2y) on the interval (- [infinity] , 3)

Sedaia [141]

Answer:

Implicit function

$\frac{d y}{d x} = \frac{-1}{2y}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given y² + x - 3=0 ...(i)

Differentiating equation (i) with respective to 'x', we get

$2 y \frac{d y}{d x} +1 = 0$

⇒ $2 y \frac{d y}{d x} = -1$

⇒ $\frac{d y}{d x} = \frac{-1}{2y}$

$\frac{d y}{d x} = \frac{-1}{2 (3)}$

$\frac{d y}{d x} = \frac{-1}{6}$
