Zeroes of a PolynomialQuiz - Solve & Score
Q1. A bakery tray of croissants cools so its surplus warmth above the shelf temperature obeys 2x + 16 degrees after x minutes; in which minute does that surplus vanish to zero?
- A.16
- B.-8
- C.8
- D.-9
Answer: B. -8
The surplus warmth is zero when 2x + 16 = 0. Then 2x = -16, so x = -16/2 = -8. Hence it happens at minute -8.
Q2. A kite caught in a breeze drifts sideways from the launcher by 3x + 21 metres during second x of flight; at which second is its sideways drift exactly zero?
- A.7
- B.21
- C.-7
- D.-8
Answer: C. -7
The sideways drift is zero when 3x + 21 = 0. Then 3x = -21, so x = -21/3 = -7. Hence it happens at second -7.
Q3. An ant marching along a ruler sits at coordinate 4x + 24 after x ticks of a metronome; on which tick does the ant rest on the origin?
- A.24
- B.6
- C.-6
- D.-7
Answer: C. -6
The coordinate is zero when 4x + 24 = 0. Then 4x = -24, so x = -24/4 = -6. Hence it happens at tick -6.
