What is the distance between the two parallel planes and ?
Answer and explanation
Correct answer: B.
- Step 1: Write both plane equations with identical normal coefficients: and .
- Step 2: The distance between two parallel planes and is .
- Step 3: Here , and . Compute: .
Answer
.
Why not the others: miscalculates as ; subtracts from directly without normalizing coefficients; uses with scaled denominator.
