Time = 2*PI* sq root [(length (in metes) / g (9.81 m / sec^2)]
Time = 2 * PI * sq root [(.43) / 9.81]
Time = 2 * PI * sq root [ <span> <span> <span> 0.0438328236 </span> </span> </span> ]

A species of animal is discovered on an island. Suppose that the population size of the species can be modeled by the following
andriy [413]

Answer:

The initial population size is of 58.

The population size of the specie after t years is given by:

P(t) = \frac{520}{1 + 8e^{-0.3t}

Step-by-step explanation:

Population size of the specie:

The population size of the specie after t years is given by:

P(t) = \frac{520}{1 + 8e^{-0.3t}

Initial population size

This is P when t = 0, that is, P(0). So

P(0) = \frac{520}{1 + 8e^{-0.3*0} = \frac{520}{1+8} = \frac{520}{9} = 57.7

Rounding to the nearest number, 58

The initial population size is of 58.
