Final answer:

The given equation represents the growth of a mosquito population in a city over time. By substituting the number of days since May 8 into the equation, we can predict the size of the population on a given day.

Step-by-step explanation:

This question involves the growth of a mosquito population in a city over time. The equation given is a exponential growth function, where y represents the size of the population and x represents the number of days since May 8. The equation y = 240,000(1.09)x can be used to predict the size of the population on a given day. For example, if x = 13, representing May 21, we can substitute this value into the equation to find the size of the population on that day. We would have y = 240,000(1.09)13. We can use a calculator to evaluate this expression and find the answer. So, the population of the mosquito in the city on May 21 is approximately equal to the calculated value.
