Answer:
For 15 years -
After 15 years -
Step-by-step explanation:
We have that,
Initial population is 110,000 which grows by the rate 4% i.e. 0.04 for 15 years.
Since, the exponential growth is given by ,
where P is the initial population, r is the rate of interest and x is the number of years.
Thus, the required population is i.e.
.
Moreover, after 15 years i.e. x+15 years, the population will be .
Thus, the population after 15 years is .
Answer:
Step-by-step explanation:
Let be the equation of this line.
The points must satisfy this equation.
When x=-8, and y=8, we get:
When x=1, and y=-10, we get:
Subtract equation (1) from equation (2) to get:
9m=-18
m=-2
We put m=-2 in equation to get (2)
-10=-2+c
c=-10+2
c=-8
Therefore the equation is:
y=-2x-8
