If A ⊂ B, then A ∩ B = A ∪ B. always, sometimes, never

Answers

Answer 1
Answer:

Answer:

Hence, the property:

            A ∩ B = A ∪ B never hold .

Step-by-step explanation:

We are given that set  A⊂B .

This means that set A is properly contained in set B.

i.e. A≠B

This means that there are some elements in set B which are not in set A.

Now we have to show whether the following property A∩B=A∪B

always, sometimes or never hold.

As A is a proper set of B.

This means that: A∩B=A ( Since A is a smaller set)

Also, A∪B=B  (Since B is a bigger set)

                   Hence, A∩B ≠ A∪B  (Since A≠ B)

Answer 2
Answer:

The answer is never.

Why did the French explore and colonize parts of North America? A.
to enslave Native Americans as workers in France

B.
to establish a democratic republic

C.
to build cattle ranches

D.
to look for gold and trap for furs

Answers

Answer:

Option D.

Step-by-step explanation:

To look for gold and trap for furs, is the right answer.

The French initially came to the United States as explorers, who were trying to find a route to the Ocean and resources. The French finally attempted to build some colonies throughout North America that abandoned, due to various reasons such as disease, weather or struggle with other European authorities. Though during the course of time, they established colonies in the Americas, their initial motive was to look for gold and trap for furs.

I think it would be b because that is what the french explores did back then

what is the equation of y=x^3 with the transformation: vertical compression by a factor of 1/2, horizontal shift 7 units to the left, reflection across the x-axis?

Answers

Assuming the transformations are in order,
because S(x,y) = (x, 1/2y), reverse what is done to y and simplify,
y = x^3 > y = 1/2*x^3 to compress vertically,
because S(x,y) = (x-7,y), reverse what is done to x,
y = 1/2*(x+7)^3 to shift to the left,
reflection across the x-axis changes positives to negatives,
y = -1/2(x+7)^3 to reflect across the x-axis.
