Answer:
See below ~
Step-by-step explanation:
<h3>What is the rat population in 1993?</h3>
⇒ Number of years since = 0 ⇒ <u>t = 0</u>
⇒ Apply in the formula
⇒ n(0) = 73e^(0.02 × 0)
⇒ n(0) = 73e⁰
⇒ n(0) = 73,000,000 rats
=============================================================
<h3>
What does the model predict the rat population was in the year 2009?</h3>
⇒ Number of years since 1993 : 2009 - 1993 = 16 ⇒ <u>t = 16</u>
⇒ Applying in the formula
⇒ n(16) = 73e^(0.02 × 16)
⇒ n(16) = 73e^(0.32)
⇒ n(16) = 73 × 1.37712776 × 10⁶
⇒ n(16) = 100.530326 x 10⁶
⇒ n(16) = 100,530,326 rats
