What is the distance between the points (−4, 5) and (3, 5)?
2 answers:
Answer:
7
Step-by-step explanation:
let the first point be A(-4, 5) and the second point B(3, 5)
the formula for distance between two points on same axes is given as
AB = √(( -
)² + (
)²)
given in the question, = 3,
= 5,
= -4,
= 5
AB = √{[3 - (-4)]² + [5 - 5]²} = √49 = 7
coordinates are generally represented as
(x, y)

Note what i actually represents.
i is the very basis of a whole new level of counting. When finding discriminants, we often say that a quadratic has no real roots if the discriminant is 0. Needless to say, there are roots, they are just imaginary.
, in real terms, is non-existent. That is, there are no numbers in the real number system that when multiplied by itself produces a result of -1. This is what i unit represents.
Let's tackle this problem in smaller steps.
Let's first expand our brackets.
(i - 7i)² = (-6i)² = 36i²
Now, let's distribute the xi.
xi(i - 7i)² = xi(36i²) = 36xi³ =
= -36xi
