Distance from (0, 4) to (4, 0)
Calculate the distance between points (0, 4) and (4, 0) using the distance formula.
Answer:
Distance = d = 4√2 ≈ 5.656854
Step-by-Step Solution
Step 1
Identify the Points
Point 1: P₁(0, 4)
Point 2: P₂(4, 0)
P₁(0, 4), P₂(4, 0)
Step 2
State the Distance Formula
For two points in 2D space:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
This is derived from the Pythagorean theorem
d = √[(x₂-x₁)² + (y₂-y₁)²]
Step 3
Calculate the Differences
Δx = x₂ - x₁ = 4 - 0 = 4
Δy = y₂ - y₁ = 0 - 4 = -4
Δx = 4, Δy = -4
Step 4
Square the Differences
(Δx)² = (4)² = 16
(Δy)² = (-4)² = 16
Sum = 16 + 16 = 32
(Δx)² + (Δy)² = 32
Step 5
Take the Square Root
d = √32
Simplified: d = 4√2
Decimal: d ≈ 5.656854
d = 4√2 ≈ 5.6569
