Answer:
Step-by-step explanation:
Equation of the line is,
y = -x + 2
By comparing this equation with,
y = mx + b
Here, m = slope of the line
b = y-intercept
Therefore, slope of the line given in the graph = (-1)
y-intercept = 2
Now we will find the table for the points lying on the line,
x -6 -4 0 4 6
y 8 6 2 -2 -4
Now plot these points on the graph and join them to get the line.
Answer: In 2008 the population was 21,525,144
Step-by-step explanation:
You need to use the following formula for Exponential decay:
Where is the initial population in the year 0,
is the rate of decay and
is the time.
In this case, you can identify that:
Therefore, substituting these values into the formula for Exponential decay, you get:
Then, in 2008 the population was 21,525,144
Answer:
2 = 2
= 2
lb.
Step-by-step explanation:
One line represents 1/16 lb.
Given:
In 2010, the population of a town = 2000
Every year, it increase by 1.5%
To find the equation P(t) which represents the population of this town t years from 2010.
Formula
If a be the original population of a town and it increases by b% every year, after t year the population will be
Now,
Taking, a =2000, b = 1.5 we get,
or,
Hence,
The population of this town t years from 2010 P(t) = , Option D.
