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.

A rectangle has a perimeter of 76 cm and length 31 cm what is its width

Snowcat [4.5K]

The formula for the perimeter of a rectangle is P = 2L + 2W

you are given P (perimeter) and l (length.

Replace the letters withe the given information and solve for width:

76 = 2(31) +2W

Simplify:

76 = 62 + 2w

Subtract 62 from both sides:

14 = 2w

Divide both sides by 2:

W = 14/2

W = 7 cm

The width is 7 cm.
