यदि अवकल समीकरण \(\frac{5+e^{x}}{2+y} \cdot \frac{d y}{d x}+e^{x}=0\), का हल \(y\) \(= y ( x )\) है, जिसके लिए \(y (0)=1\) है, तो \(y \left(\log _{ e } 13\right)\) का एक मान है

  1. A \(1\)
  2. B \(-1\)
  3. C \(2\)
  4. D \(0\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(-1\)

Step-by-step Solution

Detailed explanation

\(\frac{\left(5+ e ^{ x }\right)}{2+ y } \frac{ d y }{ dx }=- e ^{ x }\) \(\int \frac{ dy }{2+ y }=\int \frac{- e ^{ x }}{ e ^{ x }+5} dx\) \(\ln ( y +2)=-\ln \left( e ^{ x }+5\right)+ k\) \(( y +2)\left( e ^{ x }+5\right)= C\) \(\because y (0)=1\) \(\Rightarrow C =18\)…
