Living would not be possible because without the greenhouse effect the earth would be a solid rock or ice.
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
<em>expand the equation;</em>
x² - 40x + 400 = x² - 20
<em>collect similar terms together;</em>
x² - x² - 40x = -20 - 400
-40x = -420

Thus, the value of the unknown number is 10.5.

Answer:
According to the population growth graph, what can be determined about the population is that the carry capacity is around 0.4 million.
Explanation:
The graph shows the growth curve of a rabbit population, which is increasing progressively over the years until it flattens out in 2002, which is surely related to the carrying capacity of this population, established at around 0.4 million rabbits.
<u>
Carrying capacity is the maximum number of inhabitants that can be in a given place according to the space and resources available</u>. The population can increase as long as they have the necessary space and resources to support a certain number of inhabitants. When the population exceeds its carrying capacity, it experiences a decrease in growth.
<em>In the graph, the growth of the rabbit population decreased when it reached a number of inhabitants of 0.4 million.</em>
