To determine the scale factor, we first get the cube roots of the volumes of the cubes.
          (Cube 1) =     729^(1/3) = 9
           (Cube 2) =    2197^(1/3) = 13
Therefore, the scale factor of these similar polygons is 9:13.

Scale factor = (2197-729)/729===)Sale factor = 2.014

The population of a town 4 years ago was 50,000
tino4ka555 [31]

Answer:

population will be 79806.

Step-by-step explanation:

Population of a town 4 years ago  was 50,000

Population of town had grown exponentially and present population is 63,124.

So the formula of the population growth will be

A_{n}=A_{o}(r)^{n-1}

Where A_{n} = Final population n = number of years.

           A_{o} = Initial population

           r = rate of increase in population per year.

so  63124 = 50,000 (r)^{4-1}

r^{3}=\frac{63124}{50000}= 1.26428

r=(1.26428)^{\frac{1}{3} }

= 1.0813

Now we have to find the population after 4 years from now.

A_{n} =  63124(1.08)^{4-1}

       =  63124(1.08)^{3}

       = 63124 × 1.264

       = 79806

Therefore, after 4 years from now population will be 79806.

Specify three fractions with different denominators that have a LCD of 24 then arrange the fractions in order from least to grea
romanna [79]
We can just guess  20/24,     10 / 24   and 8 / 24

From the least to the greatest:

8/24, 10/24,    20/24

8/24 = 1/3            10/24 = 5/12            20/24 = 5/6

So it is:

1/3,  5/12, 5/6

I hope this helps.

Write the equation of a sine or cosine function to describe the graph.
prohojiy [21]
Y = A sin(Bx) and y = A cos(Bx). The number, A, in front of sine or cosine changes the height of the graph. The value A (in front of sin or cos) affects the amplitude (height). The amplitude (half the distance between the maximum and minimum values of the function) will be |A|, since distance is always positive.
