Answer:

P(t) = 25,000*1.12^t

Step-by-step explanation:

The populational growth is exponential with a factor of 1.12 each year. An exponential function has the following general equation:

y(x) = ab^x

Where 'a' is the initial population (25,000 people), 'b' is the growth factor (1.12 per year), 'x' is the time elapsed, in years, and 'y(x)' is the population after 'x' years.

Therefore, the function P(t) that models the population in Madison t years from now is:

P(t) = 25,000*1.12^t

Answer:

P(t)=25000(1.12)^{t}

Step-by-step explanation:

  • The town has a population of 25000.
  • The population is increasing by a factor of 1.12 each year.

This is a geometric progression since it increases by a factor.

The nth term of a geometric sequence is given by the function:

U_n=ar^{n-1}, $ where a=first term, r=common factor

Since, we the growth starts from the second year, the function that gives the population P(t) in Madison t years from now therefore is:

P(t)=25000(1.12)^{t}

7h+3s=27.95 subtract 7h from both sides

3s=27.95-7h  divide both sides by 3

s=(27.95-7h)/3

Then we are told:

5h+4s=23.4,  using s found above makes this equation become:

5h+4(27.95-7h)/3=23.4  multiply both sides by 3

15h+4(27.95-7h=70.2  perform indicated multiplication on left side

15h+111.8-28h=70.2 combine like terms on left side

-13h+111.8=70.2 subtract 111.8 from both sides

-13h=-41.6  divide both sides by -13

h=$3.20
