Answer:
A⊆B
Step-by-step explanation:
⊆ = subset
⊂ = Proper subset
Subset: A is subset of B if one or more than one or all elements of B is also element of A.
A⊆B
Proper subset: At least one element of B is not an element of A.
A⊂B
A={x|x∈N and 3<x<10]
3<x<10 means all natural number between 3 and 10.
Then A={4,5,6,7,8,9}
And B= the set of natural number between 3 and 10
B={4,5,6,7,8,9}
Since set A contains all element of B. Then A is subset of B
A⊆B
Answer:
a
Step-by-step explanation:
a
We can solve this using the distance formula:
<span>d=√(x2-x1)² + (y2-y1)²
d=</span>√(-1-11)² + (5-5)²
d=√(-12)² + 0
d=12
Answer:
4
Step-by-step explanation:
The ratio of the area of similar figures is the ratio between corresponding sides squared. This means that 64/4 or 16 is the square of the ratio of corresponding sides. By taking the square root of 16, we get that ratio is 4.
