The magnitude of a vector is the length of the vector. It is also known as the modulus of the vector. For any vector of the form <a,b>, the length is equal to sqrt(a^2+b^2). Note how this follows from the pythagorean theorem.
Commutative because it’s switching the numerals to make an equation
The correct answer would be A. Hope this helps!
Answer:
The best estimate for the given calculation is 2.8.
Step-by-step explanation:
To determine the correct option regarding the result of this calculation, the mathematical resolution of the same must be developed:
-14 x 1 /9 x (-2 x 9/10) = X
-14 x 1 / 9 x (-18 / 10) = X
-14 x 1 / 9 x -1.8 = X
-14 / 9 x -1.8 = X
-1.555555 x -1.8 = X
2.8 = X
Therefore, the best estimate result for this mathematical operation is 2.8.
