Question
Determine the following limit.
\[
\lim _{t \rightarrow \infty}\left(-11 t^{-3}\right)
\]
Select the correct answer and, if necessary, fill in the answer box to complete your choice.
A. $\lim _{t \rightarrow \infty}\left(-11 t^{-3}\right)=$ $\square$
B. The limit does not exist and is neither $-\infty$ nor $\infty$
Solution
Solution Steps
To determine the limit of the function \(-11 t^{-3}\) as \(t\) approaches infinity, we observe that as \(t\) becomes very large, the term \(t^{-3}\) (which is equivalent to \(\frac{1}{t^3}\)) approaches zero. Therefore, the entire expression \(-11 t^{-3}\) approaches zero as well.
Step 1: Analyze the Function
The function given is \(-11 t^{-3}\), which can be rewritten as \(-\frac{11}{t^3}\). As \(t\) approaches infinity, the term \(t^3\) becomes very large.
Step 2: Evaluate the Limit
Since \(\frac{1}{t^3}\) approaches \(0\) as \(t\) approaches infinity, the expression \(-\frac{11}{t^3}\) also approaches \(0\).
Final Answer
The limit of the function as \(t\) approaches infinity is \(\boxed{0}\). Therefore, the correct answer is A.
