$lim_{t \to \infty} 40 e^{- t}$

Step 1

Move the term $40$ outside of the limit because it is constant with respect to $t$ .

$40 lim_{t \to \infty} e^{- t}$

Step 2

Since the exponent $- t$ approaches $- \infty$ , the quantity $e^{- t}$ approaches $0$ .

$40 \cdot 0$

Step 3

Multiply $40$ by $0$ .

$0$
