Answer:

3.43

Explanation:

Data provided in the question:

Time taken for the given growth in population = 88 years

Initial population, n = 1,200

Total population, N = 4,800

Now,

we know

Total population is given as:

N = n + [ rn( (k - n) ÷ k ) ]

here,

r is the intrinsic growth rate

k is the Carrying capacity = 2N = 2 × 4,800 = 9,600

on substituting the respective values, we get

4,800 = 1,200 + [ r × 1,200( (9,600 - 1,200) ÷ 9,600 ) ]

3,600 = r × 1,050

r = 3.43

MOVEMENT How would you describe the difference between changes in the geographic center and changes in the population center?

lesantik [10]

Answer:

The mean center of population is the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Historically, the movement of the center of population has reflected the expansion of the country, the settling of the frontier, waves of immigration and migration west and south. Since 1790, the center of population has moved steadily westward, angling to the southwest in recent decades.

Consulted for historical reference: Historical Atlas of the United States, National Geographic Society, 1988.

NOTE: The Proclamation Line of 1763 limited British settlement to areas east of the Appalachian Mountains. Alaska and Hawaii were not included in the calculation of the mean center of population until 1950. Puerto Rico was not included in any decade.

Analyze the image below and answer the question that follows.

Grace [21]

Answer:

It should be the Prime Meridian.

Explanation:

You do not have a picture but the equator is a line of latitude that travels east to west. The International Date line is an imaginary line through the Pacific Ocean that begins a new day (it has to do with time zones). The Arctic Circle is only in the north and it is a circle, not a line. Lastly, the prime Meridian is a line of longitude that travels from north to south and cuts the world in half between eastern and western hemispheres, like the Equator cuts the globe into the northern and southern hemispheres. The Prime Meridian goes through the Atlantic Ocean and cuts off put of Africa.

I hope this helps!
