A city that had 8000 thousand people at the beginning of the year 2000 has been decreasing by 3.2% per year. What is the 1-year
Margaret [11]

Answer:

7,744 (96.8% of population at the beginning of the year)

Step-by-step explanation:

Population of the city at the beginning of the year = 8000people

Yearly percentage decrease = 3.2%

This means at the end of the first year the population reduces by 3.2% which gives 3.2%of 8000

= 3.2/100 × 8000

= 3.2 × 80

= 256

This shows that the population decreases by 256 at the end of first year.

To get the 1year percentage change in population, we will subtract the percentage decrease in Population from the initial population to give;

8000 - 256

= 7,744

7,744population remains after 1year wish is (100-3.2)% i.e 96.8% of the population at the beginning of the year.

The table below represents the distance of an airplane from its destination as a function of time:
Ira Lisetskai [31]
Let us first find the equation for the distance as a function of time in the form:

d=mx+b

m=(d2-d1)/(x2-x1)

m=(2160-2700)/(1-0)

m=-540

d=-540x+b, using point (0,2700) we can solve for b

2700=-540(0)+b

2700=b so

d(x)=-540x+2700

A)  The y-intercept is the constant of our distance function  (the distance when x, time, equals zero).  In this case d=2700 is the y-intercept.  This means that the initial distance from the destination was 2700 miles.

B) Since this is just a line and has a constant velocity, its average velocity will just be the constant velocity or slope.  But mathematically we could show this to be true.  Average velocity is change in distance divided by change in time.

v=(540-2160)/(4-1)

v=-1620/3

v=-540 mph

C)

The domain of a function is the possible x values in the proper context.  First time cannot be less than 0.  The other extreme for time is when the plane reaches its destination, when d=0, which is when:

-540x+2700=0

540x=2700

x=5.  

So the plane reaches its destination after 5 hours.  So the domain, the x values, for d=-540x+2700 is

x=[0,5]
