Answer:
B is a subset of set A because every element of set B is contained in set A
Step-by-step explanation:
The answer to this question is:
B is a subset of set A because every element of set B is contained in set A.
We can denote it as B⊆A
<u>Subset:</u>
A subset is a set of elements that are also in another set. Another way to define a subset is: B is a subset of A if every element of B is contained in A.
It is denoted by B⊆A ....

w = 180
You didn't provide a list of equations to select from, so let's see about creating them and solving. For this I'll use the variable p for the airspeed of the jet and w for the speed of the wind in the jet stream. So when the jet is traveling in the same direction as the jet stream, the ground speed is p+w and when the jet is traveling in the opposite direction, the ground speed is p-w. With that in mind, we can create two equations and solve them. The equations are:
(1). 1920 = 2(p+w)
(2). 1920 = 3.2(p-w)
Let's take equation (1) above and distribute the 2.
1920 = 2(p+w)
(3) 1920 = 2p + 2w
And do the same for equation (2) above.
1920 = 3.2(p-w)
(4) 1920 = 3.2p - 3.2w
Let's multiply (3) above by 1.6 to make the w terms equal in magnitude and opposite in sign to that in equation (4) above.
1920 = 2p + 2w
(5) 3072 = 3.2p + 3.2w
Add (4) and (5) above together, then solve for p
(4) 1920 = 3.2p - 3.2w
(5) 3072 = 3.2p + 3.2w
4992 = 6.4p
780 = p
So the Jet's speed is 780 km/h
Now use the speed of the Jet and (1) above to get the wind speed.
1920 = 2(p+w)
1920 = 2(780+w)
960 = 780 + w
180 = w
So the wind speed is 180.</span>
The question is incomplete. The complete question is :
A population of mutant Venus fly trap plants are taking over an island in the South Pacific, capturing everything from insects to small rodents. When they were first discovered they covered 4 square kilometers. As the population grows, the plants spread and cover more land. Use the table to write an equation.
Solution :
It is given that:
Venus fly trap plant is capturing everything on its way from small insects to other small rodents.
When they were first discovered, it covered an area of 4 square kilometers. But as more population grew and as years passed by, they spread over large land and covered more land.
Now from the table, it is seen that :
It covered 4 km square when discovered.
Then it covered 6.68 km square in the first year.
It covered 11.16 km square in the second year.
It covered 18.63 km square in the third year.
It covered 31.11 km square in the fourth year.
Therefore the equation which represents the growth is given by :
