Answer: The population after 10 years is 33500

Step-by-step explanation:

The current population of the town is 25000. It increases at a rate of 3%

The formula for compound interest is expressed as

A = P(1+r/n)^nt

Where

A represents the final value at the end of t years.

t represents time in years.

n represents the periods of increase.

r represents growth rate

P represents initial or current value.

From the information given,

r = 3%

t = 10 years

Looking at the compound interest table, the columns represents the growth rate while the the rows represents the number of years.

Therefore, the compound interest multiplier for 3% and 10 years is 1.34

Therefore

The population after 10 years would be

1.34 × 25000 = 33500

Step-by-step explanation:

Let the population after 10 years be x.

\therefore \: x =25000 \times  (1 +  \frac{3}{100} )^{10}  \\  \\  \therefore \: x = 25000 \times (1 +  0.03 )^{10} \\  \\  \therefore \: x =25000 \times  (1.03 )^{10}  \\  \\ \therefore \: x = 25000 \times 1.34391638  \\  \\ \therefore \: x =33,597.9095 \\  \\  \therefore \: x \approx \: 33598

Thus, the population of the town after 10 years would be 33598.

you can only see values of x Ranging from $-3$ to $3$ and they're included, so domain is $[-3,3]$

and $y$ values ranging from $-2$ to $4$ but $-2$ is not included so range is $(-2,4]$

Answer:

28.75 or 28 3/4

Step-by-step explanation:

This equation is made for Long Division:

115/4

4 cannot go into 1 evenly.

4 can go into 11, 2 times.

4x2=8

11-8=3

4 can go into 35, 8 times.

35-32=3

Add a zero at the end, then divide 4 into 30.

4 goes into 30, 7 times.

30-28=2

Add another zero, then divide again.

4 goes into 20, 5 times.

20-20=0

So, after you hit an even number you can stop dividing and put in your answer.

28.75
