Economic Growth The value of sold goods in Mexico can be approximated by
Where t is time in months since January 2005. Numerically estimate limt→+∞ v(t) and interpret the answer. HINT [See Example 6.]
Example 6:
The percentage of U.S. Internet-connected households that have broadband connections can be modeled by
where t is time in years since 2000.*
a. Estimate limt→+∞ P(t) and interpret the answer.
b. Estimate limt→0+ P(t) and interpret the answer.
Solution
a. Figure 8 shows a plot of P(t) for 0 ≤ t ≤ 20.
Using either the numerical or the graphical approach, we find
Thus, in the long term (as t gets larger and larger), the percentage of U.S. Internet connected households that have broadband is expected to approach 100%.
We need at least 10 more requests to produce the solution.
