The current population of Fun City is 21000 people. If the population of the city will double every 51 years then the population
Arisa [49]

Answer:

The population of Fun City after 171 years would be 214563.

Step-by-step explanation:

The statement depicts a case of exponential growth, whose model is described below:

p(t) = p_{o}\cdot r^{\frac{t}{T} } (1)

Where:

p_{o} - Initial population, no unit.

p(t) - Current population, no unit.

r - Growth rate, no unit.

t - Time, in years.

T - Growth period, in years.

If we know that p_{o} = 21000, r = 2, t = 171\,yr and T = 51\,yr, then the population of the city after 171 years is:

p(t) = 21000\cdot 2^{\frac{171}{51} }

p(t) = 214563

The population of Fun City after 171 years would be 214563.

How do you divide 54,164 by 44 and show your work
sergejj [24]
To divide 54,164 by 44, we start from the first digit.

First we take the first 2 digits: i.e. 54 divided by 44, which gives 1 remainder 10.

Next, we join the next digit to the remainder and divide again by 44: i.e. 101 divided by 44, which gives 2 remainder 13.

Next, we join the next digit to the remainder and divide again by 44: i.e. 136 divided by 44, which gives 3 remainder 4.

Next, we join the next digit to the remainder and divide again by 44: i.e. 44 divided by 44, which gives 1.

We now joining all the results from our algorithm, to get that 54,164 divided by 44 is 1,231.
