Step-by-step explanation:
By Pythagoras' theorem,
12^2 = 11^2 + height^2
height = ±√12^2 - 11^2 (rej -ve value since height > 0)
height = 16.279 (5sf) = 16.3 (nearest tenth place)

What is the system that you have to solve to find the value of x and y?
The candle sales decreases to - 15 percentage.
<u>Step-by-step explanation:</u>
(476 - 560) : 560 x 100
= (476 : 560 - 1)100
= 85 - 100 = - 15
Therefore, - 15% did the candle sales decrease.
The perpendicular slope is expressed as the negative reciprocal of the slope or − 1 m. In this scenario, the slope, or m, is −4 so the slope of the perpendicular line is − 1 −4 which simplifies to 1 4
