A yacht P left port and sailed 45 km on a bearing of 290°. Another yacht Q left the same port but sailed for 50km on a bearing of 040°.
a )What was the angle between their directions?
b )How far apart were they at that stage (correct to two decimal places)?

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

1. 34

2. 268

3. x=14.4

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
