hi

here is  the  method :

you take  Value 1  and Value 2

And you do :   ( Value 2 - Value 1)  / (Value 1 )    * 100

Here we have :    Value 1 = 352 000

                            Value 2 =  337 920

So now we apply :

( 337 920 - 352 000 )  /  ( 352 000)   * 100 =  -4  

Population decreased by by  4 %

You can also make :  

352 000 * X = 337 920

                 X =  337 920 / 352 000

                 X = 0.96

if  the multiplier is  0.96 ,  it's mean that we lost  1 -0.96 = 0.04  

which mean  - 4%

A certain forest covers an area of 2,000 square kilometers. Suppose that each year this area decreases by 6%. What is the functi
Trava [24]

The question gives you the formula to use, but it's printed wrong.
The 'x' is an exponent after the (1 + r).

All you have to do is take the formula, and write the numbers into it
that are also given.

The key thing to spot is that the forest is <u><em>decreasing</em></u>, so the 'r' is <u>negative</u>,
just as if you had money in a savings account and every year the bank took
6% <u>out</u> of it.

So the formula to use is       f(x)  =  P (1 + r) ^x

P = 2000
r = -0.06
                        f(x)  =  2000 (1 - 0.06)^x
                               =  <em>2000 (0.94)^x</em>

The amount left after 12 years is
        
                                   2000 (0.94)¹² =

                                   2000 (0.476)  =<em>  951.8 square kilometers</em>.

Write an equation in point-slope form -2,-5 4,-1
rosijanka [135]

Answer:

Step-by-step explanation:

first find the slope

m = Δy/Δx = (-1 - (- 5)) / (4 - (-2)) = 4/6 = 2/3

Then plug either point into the equation

y - y₁ = m(x - x₁)

y + 1 = 2/3(x - 4)

which is equivalent to

y + 5 = 2/3(x + 2)

1 meter = 0.001 km

400 m x 0.001 m/km = 0.4 km

Now add all three distances:

Total distance = 0.4 + 40.1 + 12.2 = 52.7 km.

The answer is B.
