A candle’s length decreases linearly with time. If its model is \(L(h)=36-3h\), what does the coefficient \(-3\) of \(h\) represent?

Answer and explanation

Correct answer: मोमबत्ती की लंबाई हर घंटे 3 सेमी घटती है

In \(L(h)=36-3h\), the coefficient of \(h\) is the rate of change. Its negative sign shows decay, so the candle loses 3 cm each hour. The value 36 is the initial length. Exam tip: always check the sign of the slope.
