Answer:

Casey will take 3 minutes to clean \frac{5}{6} part of the section.

Step-by-step explanation:

∵ Casey takes the time to cleans \frac{5}{18} of a section = 1 minute

∴ He will take the time to clean complete section = \frac{1}{\frac{5}{18} }

                                                                                  = 1\times \frac{18}{5}

                                                                                   = 3.6 minutes

Now time taken to clean \frac{5}{6} part of the section = \frac{5}{6}\times 3.6

                                                                            = 3 minutes

Therefore, left part of the section will be cleaned by Casey in 3 minutes.

The growth of a city is described by the population functionwhereis the initial population of the city, t is the time in years,
mamaluj [8]

Complete question:

The growth of a city is described by the population function p(t) = P0e^kt where P0 is the initial population of the city, t is the time in years, and k is a constant. If the population of the city atis 19,000 and the population of the city atis 23,000, which is the nearest approximation to the population of the city at

Answer:

27,800

Step-by-step explanation:

We need to obtain the initial population(P0) and constant value (k)

Population function : p(t) = P0e^kt

At t = 0, population = 19,000

19,000 = P0e^(k*0)

19,000 = P0 * e^0

19000 = P0 * 1

19000 = P0

Hence, initial population = 19,000

At t = 3; population = 23,000

23,000 = 19000e^(k*3)

23000 = 19000 * e^3k

e^3k = 23000/ 19000

e^3k = 1.2105263

Take the ln

3k = ln(1.2105263)

k = 0.1910552 / 3

k = 0.0636850

At t = 6

p(t) = P0e^kt

p(6) = 19000 * e^(0.0636850 * 6)

P(6) = 19000 * e^0.3821104

P(6) = 19000 * 1.4653739

P(6) = 27842.104

27,800 ( nearest whole number)
