Answer:
12
Explanation:
To find the number of fish in the pond on the first day of filming, we need to evaluate the function N(t) when t = 0 (since t is measured in weeks, t = 0 represents the first week).
When t = 0, we have:
N(0) = 12(1 + 0.04)^0
Since any number raised to the power of 0 is 1, we have:
N(0) = 12(1)
Therefore, the number of fish in the pond on the first day of filming, based on the given function, is 12.
It's worth noting that this calculation assumes that the number of fish in the pond remained constant over the 10-week period between when the producers investigated the island and the first day of filming. In reality, the number of fish in the pond may have changed due to various factors such as predation, disease, or environmental conditions.
