In the year 2000, the population of town a was 5,000 people. in the year 2010, the population grew to 6,500 people. assuming the rate of growth was exponential, write down a function p(t) which models the population of town a as a function of time t-years since the year 2000. what will be the population in the year 2030?

Step-by-step explanation:

The population grew by a factor of 6500/5000 = 1.3 in the 10 years between 2000 and 2010, so the exponential function can be written as ...

  P(t) = 5000·1.3^(t/10)

__

Then in 30 years, the population will be modeled as ...

  P(30) = 5000·1.3^(30/10) = 5000·2.197

  P(30) = 10,985

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
