The distance between two points knowing theirs coordinates:
AB =√[(x₂-x₁)² +(y₂-y₁)²]; ===>A(5,-4) & B(-3,-1) Given
A(x₁,y₁) & B(x₂,y₂)
AB =√[(-3-5))²+(-1-(-4)²] =√(73) = 8.381 ≈ 5.44 units
Answer:
Face diagonal of a cube:
Step-by-step explanation:
f2 = a2 + a. Then f2 = 2a.
Answer: 1000
Step-by-step explanation:
open () to make 9f-6>5f-3
minus 5f to make 4f-6>-3
add 6 to make 4f>3 so f >3/4
