Question

The equation LaTeX: p=5000\cdot2^tp = 5000 ⋅ 2 t represents the population of an invasive fish species in a large lake, years since 2005, when the fish population in the lake was first surveyed.


What was the population in 2005?

Answer 1

Answer:

10000 fish species

Step-by-step explanation:

Given

$p=5000\cdot2^t$

Required

Find the population in 2005

2005 is the first year

So: $t = 1$

Substitute 1 for t in $p=5000\cdot2^t$

$p=5000\cdot2^t$

$p = 5000 * 2^1$

$p = 5000 * 2$

$p = 10000$
