Welp that was wrong sorry lol. Uuh, what he said^ :
Answer:
The value of Y is either 0.8 cm less than the ideal length or 0.4 cm more than the ideal length.
Y = - 0.8 cm or Y = +0.4 cm
Step-by-step explanation:
ideal length = 0
X = - 0.2 cm
|X - Y| = 0.6 cm
X - Y = 0.6 or X - Y = - 0.6
X - Y = 0.6
-0.2 - Y = 0.6
-Y = 0.6 + 0.2
Y = -0.8 cm
Or
X - Y = -0.6
-0.2 - Y = -0.6
-Y = -0.6+0.2 = -0.4
Y = 0.4 cm
The plot of the possible points on the number line that Y could be, is attached to this solution.
It is evident that the value of Y is either 0.8 cm less than the ideal length or 0.4 cm more than the ideal length.
Hope this Helps!!!
Answer:
Below.
Step-by-step explanation:
I've drawn the answers to (c) and (g) in the attached picture.
First mark the radar point and draw the N line vertically up from this point.
The bearing is the angle, drawn clockwise, from The North (N) line on the radar point. The lines drawn are 5 and 6.5 cms long to indicate the 5 and 6.5 miles.
I have estimated the angles. To draw them accurately you'll need a protractor.
X^2=4x+12
x^2-4x-12=0
(x+2)(x-6)=0
x=6 is the answer
