An army of orcs has marched upon King Amit's stronghold, setting up camp a safe distance away (or so they think!). What the orcs
don’t know is that the king and his engineers have spent the past decade developing advanced catapulting technology. King Amit has created a map to help him compute the distance from each of his two best catapults to the enemy orc camp (shown below). To what distance should King Amit calibrate catapult B to fire?

Answer:
b
Step-by-step explanation:
In general
Given
y = f(x) then y = f(Cx) is a horizontal stretch/ compression in the x- direction
• If C > 1 then compression
• If 0 < C < 1 then stretch
Consider corresponding points on the 2 graphs
(2, 2 ) → (4, 2 )
(4, - 2 ) → (8, - 2 )
Indicating a stretch in the x- direction.
y = f( ) with C =
, that is 0 < C < 1
stretches the graph in the x- direction by a factor of 2
Thus
y = f( ) → b
Answer:
37°
Step-by-step explanation:
(4x + 2)° = 150° [Vertically Opposite Angles]
=> 4x = 150 - 2
=> 4x = 148
=><u> x = 37° (Ans)</u>
