Answer:

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

So then we need to replace the value of x =3 and we got:

Step-by-step explanation:
For this case we have the following function:

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

So then we need to replace the value of x =3 and we got:

Answer:
The relation is discrete function
Domain is {x|x = 2,2,2}
Range is {y|y = 4, -1, -3}
Step-by-step explanation:
I. This function is discrete because x = 2,2,2
and y = 4, -1, -3
Or (2,4), (2,-1) and (2,-3)
If this function is continuous, the x and y will be something like this -3 <= x <= 3
II. Domain is x.value
III. Range is y.value
Ask me for anything.
You can split the combined shape into separate shapes and find the area of each of those. once you have done that add all of the areas together and that will get you your combined shapes area.
Percent decrease { (original number - new number) / original number....x 100
percent decrease : (75 - 25) / 75....x 100
50 / 75...x 100
0.666 x 100
66.6% decrease <==not sure if u need it rounded ?
