A population of 2000 starfish has a yearly per capita population growth rate of 0.012. By next year, how do you expect populatio
Alona [7]

Answer:

It will increase by 24 starfish

Step-by-step explanation:

The population is modeled by the following differential equation:

\frac{dN}{dt} = rN

Which has the following solution:

N(t) = N(0)e^{rt}

In which N(0) is the initial population and r is the growth rate.

A population of 2000 starfish has a yearly per capita population growth rate of 0.012.

This means that N(0) = 2000, r = 0.012

By next year, how do you expect population size to have changed?

This is N(1).

N(t) = N(0)e^{rt}

N(1) = 2000*e^{0.012}

N(1) = 2024

2024 - 2000 = 24

So the correct answer is:

It will increase by 24 starfish

A circuit contains two capacitors rated at 0.02 microfrads and 0.05 microfrads connected in series the circuits Source voltage i
Neporo4naja [7]

Answer:

  about 0.0143 microfarads

Step-by-step explanation:

The effective capacitance of capacitors in series is the reciprocal of the sum of their reciprocals:

  1/(1/0.02 +1/0.05) = 1/(50+20) = 1/70 ≈ 0.0143 . . . microfarads
