Question

Transcribed Image Text:Gwyneth is developing a computer game based on the popular game
Battleships. The objective of the game is to fire missiles to try to sink each
other's ships. The trajectory of a missile after it is fired from a ship is
modelled in the computer code by a quadratic equation of the form
y = ar? + br + c,
where y represents the height (in centimetres) of the missile above the
virtual sea, and z represents the horizontal distance (in centimetres) of the
missile from the position where it was launched. The values of a, b and c are
determined by the computer code that Gwyneth writes, and depend on the
angle and force at which the missile is launched. You may assume that the
virtual sea area where the battle takes place is completely flat and horizontal.
(a) The quadratic equation produced to model the trajectory of a test
missile is
y = -0.08z? + 2.15r + 0.38.

Transcribed Image Text:(b) In a simulation, an opponent's ship is positioned 32 cm away
horizontally. Explain why the test missile can't possibly hit the
opponent's ship.
