Explanation

A metric space is a set with a distance function (metric) that meets three properties: 

1. Non-negativity: Distances are always non-negative.  

2. Symmetry: Distance from A to B equals distance from B to A.  

3.  Triangle Inequality: For any points A, B, and C, the distance from A to C is less than or equal to the sum of the distances from A to B and B to C.

Explanation

(2+5)-4+(5-3)=?

7-4+2=

9-4=5

Explanation

Value of x is 100

Because 6250/10=625.

Explanation

1 is the correct answer

 sin 45= 1/sq.root 2 cosec =sq root 2 just so they cancelled each other answer=1

Explanation

1+2+3+4+5+6+7+8+9+10 = 55 multiply by 7 = 55x7 = 385 as 10 units so divide by 10 to find averages value= 385/10=38.5.
