Albert drives a distance of 55 km on a bearing of 284° from a point A to a point B. He then drives a further 60 km on a bearing of 50 to C. (a) Draw a clearly labelled diagram to represent this information. (b) Calculate: (i) the angle ABC (ii) the distance AC (iii) the angle BAC (iv) the bearing of C from A.

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

3       6.8

step-by-step explanation:

linear pair postulates

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
