If (X(t)=5+4t), what is the difference between (X(3)) and (X(0))?यदि (X(t)=5+4t), तो (X(3)) और (X(0)) का अंतर क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(12\)\(12\)
\(X(3)=5+4\times3=17\) and \(X(0)=5+4\times0=5\). Therefore, the difference is \(17-5=12\). Option \(17\) is the value of \(X(3)\), not the difference. Exam tip: For a linear expression, substitute both time values separately and then subtract the results.\(X(3)=5+4\times3=17\) और \(X(0)=5+4\times0=5\) है। अतः अंतर \(17-5=12\) होगा। विकल्प \(17\), \(X(3)\) का मान है, अंतर नहीं। परीक्षा टिप: रैखिक व्यंजक में दो समयों का अंतर निकालते समय दोनों मान अलग-अलग रखकर घटाएँ।
