A city block has 6 pigeons and then 1 week later there are 9 pigeons. Let P(t)be the number of pigeons where t is measured in we
Pavel [41]

Using proportions, it is found that the differential equation which describes the growth of the pigeon population is given by:

\frac{dP}{dt} = 1.5P

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, considering the initial population and the population one week later, the rate of growth is given by:

k = 9/6 = 1.5.

The standard differential equation for population growth is:

\frac{dP}{dt} = kP

Hence:

\frac{dP}{dt} = 1.5P

Evaluate 11011-101 base 2
choli [55]

11011 - 101 = 10110 (putting the zero in front does not matter)

Base two only accommodate 1's and 0's. Base two are called binary.

Check the picture below

Note 10 - 1 in binary equals 1

when we borrow to 1, that zero becomes 10, then 10 minus 1 equals 1.
