Question

Please help!!!! i don’t understand any of this and really need it.

Answer 1

Answer:

B) 3.2 mi

Step-by-step explanation:

1. The midpoints: midpoint formula = ((x₁ + x₂)/2, (y₁+ y₂)/2)

upper = ((6 + -4)/2, (8 + 0)/2) --> (1, 4)

lower = ((-8 + 2)/2, (3 + -5)/2) --> (-3, -1)

2. Distance: distance formula = √((x₁ - x₂)² + (y₁ - y₂)²)

√((1 + 3)² + (4 + 1)²) = √(16 + 25) = √41 ≈ 6.403... ≈ 6.4

3. Scale: 6.4 * 0.5 mi = 3.2 mi
