3^2 = 9
21^2 = 441
9 x 441 =
3969
2) If we have 2 points K & M with their coordinates (x₁,y₁) & (x₂,y₂), the the distance of KM is given by the formula:
KM = √[(x₂-x₁)² + (y₂-y1)²] ; K(2,3) & M(5,1) (Given)
KM = √[(5-2)² + (1-3)²] ==>√(9+ 4) ==> KM = √13 (ANSWER D)
3) The coordinates are A(4,7) & B(-3,9). Follow & apply the same methodology as above:
AB =√[(x₂-x₁)² + (y₂-y1)²] ; A(4,7) & B(-3,9) (Given)
AB =√[(-3-4)² + (9-7)²] ==> AB = √[(-7)² + (2)²] ==> √(49+4) =√53 (B)

Answer:
The number is 0.000358 lbs.
Step-by-step explanation:
Scientists found that the body of a male consists of
lbs of zinc.
This is a scientific way of writing a number.
For, example 0.0023, a number in normal or standard notation can be scientifically written as
.
So, in our case, the number is
lbs and we have to write this number in standard notation.
Then the number is 0.000358 lbs. (Answer)
