Answer:
a)
b) The population increases 7.1% each year.
Step-by-step explanation:
The continuous population growth model is given by:
In which is the population after t years,
is the initial population and r is the growth rate.
In this problem, we have that:
A population grows from its initial levelof 22,000 at a continuous growth rcte of 7.1% per year.
This means that
a) Write a function to model the population increase.
b) By what percent does the populaiion increase each year?
So the population increases 7.1% each year.
Answer:
The length of the resulting segment is 500.
Step-by-step explanation:
Vectorially speaking, the dilation is defined by following operation:
(1)
Where:
- Center of dilation.
- Original point.
- Scale factor.
- Dilated point.
First, we proceed to determine the coordinates of the dilated segment:
(,
,
,
)
Then, the length of the resulting segment is determined by following Pythagorean identity:
The length of the resulting segment is 500.
