Suppose P(t)represents the population of a certain mosquito colony, where. t is measured in days. The current population of the
Darina [25.2K]

Answer:

The estimated size of the population in 10 days is of 1372 mosquitos.

Step-by-step explanation:

Population after t days:

The population after t days is given by:

P(t) = P(0)e^{rt}

In which P(0) is the initial population and r is the growth rate, as a decimal.

P(0)=574.

So

P(t) = 574e^{rt}

P'(0)=50

P^{\prime}(t) = 574re^{rt}

Since P'(0)=50

574r = 50

r = \frac{50}{574}

r = 0.0871

So

P(t) = 574e^{0.0871t}

Estimate the size of the population in 10 days

This is P(10).

P(10) = 574e^{0.0871*10} = 1372

The estimated size of the population in 10 days is of 1372 mosquitos.

Can you please help?
Ivanshal [37]
The answer is 1km every 4 minutes

Why? Because it took them 20 minutes to run a 5 km race and so I made a fraction. 5km/20mins and then I simplified to 1km/4mins. 1km every 4 mins.
