Answer: 
.
Step-by-step explanation:
It is given that,
Initial population of a town = 2000
Growth rate = 4% = 0.04 per year
The exponential growth function for population is
where, 
is initial population, r is growth rate and t is number of years.
Substitute 
in the above equation.
Therefore, the required equation is , where P is population after t years.
Answer:
13= -14x
Step-by-step explanation:
(4×2)-(4×1x)=(5×1)-(5×2x)
8-4x=5-10x
8+5=-4x-10x
13=-14x
Hopefully this will help
7 books costs $14, etc. We have points in a line
(7,14)
(8,16)
(9,18)
They're all points on the line y=2x which just means it costs $2 a book. So 1 book costs $2, 2 cost $4, and 3 cost $6. We have three new points:
(1,2)
(2,4)
(3,6)
They're all on the same line, y=2x, just closer to the origin than the first three. We plot a point at x=1, y=2, etc.

Answer:
B. $271
Step-by-step explanation:
Given,
Present value of the loan, PV = $ 6000,
Annual rate of interest = 8 % = 0.08,
So, the monthly rate of interest, r = 
,
Also, time = 2 years,
So, the total number of months, n = 24,
Hence, the monthly payment would be,
Option B is correct.
Answer:
9^-4
Step-by-step explanation:
9^-6=?*9^-2
Let the unknown=x
9^-6=x*9^-2
9^-6=9^-2(x)
x=1/9^6÷1/9^2
=1/9^6×9^2/1
=9^2/9^6
x=1/9^4
x=9^-4
Check
9^-4*9^-2
=9^-4-2
=9^-6
