Answer:
AB ≈ 8.1
Step-by-step explanation:
Calculate the distance AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(4, - 3) and (x₂, y₂ ) = B(3,5)
AB =
=
= ≈ 8.1 ( to the nearest tenth )
You are looking at a computer printout of 100 test scores, which have been converted to standard units. The first 10 entries are - 3.1 2.4 0.18 0.56 0.32 0.74 0.99 0.0244 3.7. Does the printout look reasonable, or
Answer: A'(-3, 7), B'(3, 6), C'(-7, -2)
Reflecting over y = x maps (x,y) onto (y,x).
