<h3>Answer: 395 birds</h3>
==============================================
Work Shown:
The formula to use is
A = P*(1+r)^x
where,
P = 12000 is the initial population
r = -0.15 represents the growth rate in decimal form; which is really a decay/decrease due to r being negative
x = 21 days have passed by (3 weeks = 3*7 = 21 days)
These values lead to...
A = P*(1+r)^x
A = 12000*(1+(-0.15))^21
A = 12000*(1-0.15)^21
A = 12000*(0.85)^21
A = 12000*0.03294560142183
A = 395.34721706196
A = 395
To make any meaningful calculations here, you'll have to think about how the area of each room is calculated, as well as to invent how much per square yard the various types of carpeting cost.
Note that the cost of carpeting one room would be (room area)(carpet cost per square foot).
Answer: 6.38905609893
Step-by-step explanation:
The slope of a line going through points (5,7) and (3,1) is 6/2 so 3/1 = slope of 3
