A B denotes to all common elements in both A and B
- Sample space=S={1,2,3,4,5,6,7,8,9,10}
So
- A={1,2,8}
- B={2,7}
2 is common
Hence
A $\cap$ B={2}
Hello!
To find how far the ship has sailed, we need to use the distance formula. The distance formula is: .
Before using the formula, we need to assign the given points to and
. The point (1, 2) can be assigned to
and (5, 5) can be assigned to
.
With the assigned ordered pairs, we can substitute it into the formula.
Given that each unit represents one mile, then therefore the ship has sailed 5 miles, which is choice A.
The distance between (3, 2) and (-3, -6) is 10 units
The correct answer is B) 10
Further explanation:
Given points are:
(x1,y1) = (3,2)
(x2,y2)=(-3,-6)
The distance formula is given by:
Putting the values
The distance between (3, 2) and (-3, -6) is 10 units
