The first thing we are going to do is find the area of the field. To do this we are going to use the area of a square formula: 
Were
is the area in square kilometers
is one of the sides of the square
We know for our problem that the side lengths of the field are 0.9 kilometers, so
. Lets replace that value in our formula to find :
Now, to find the population density of the filed, we are going to use the population density formula:
where
is the population density in <span>in burrows per square kilometer
</span>
is the number of burrows
is the are of the field
We know that
and , so lets replace those values in our formula:
We can conclude that the <span>density of prairie dog burrows is approximately 2444 burrws per square kilometer.</span>

Answer:
There are none.
Step-by-step explanation:
<u>No calculus involved:</u>
The line, in slope-intercept form, has equation , ie is always decreasing (easy to spot applying the definition)
Meanwhile, is always increasing over its domain.
At no point the tangent will be decreasing.
<u>Let's use calculus</u>
We are to solve the equation which has no real solutions.
