Answer:
Two answers are possible
Step-by-step explanation:
Both are listed below
Answer: Hi!
First, if you think that a compass has degrees as units, then N50E would be
50 degrees from north in the direction of the east, so if you put our 0 in east and count counterclockwise this will be an angle of 40 degrees.
If you think north has te Y axis positive direction, and east as the X axis positive direction. then the first boat has an angle of 40° counterclockwise from the +x
so the velocity in y is Vy=30mph*sin(40°) and in x is Vx= 30mph*cos(40°)
then the total displacement will be 22.98m to east and 19.28 north
the second one goes to s 70 e, so using the same notation as before, you can write this has -20° degrees count counterclockwise.
so decomposing the velocity will give us
Vy = 26*sin(-20°) and the displacement in Y is -8.89m
Vx = 26*cos(-20°) and the displacement in X is 24.43m
so the distance between the boats in y will be 19.28m - (-8.99)m = 28.27m
and in x: 24.43m - 22.98m = 1.45m
and the total distance is 
so D = 28.30 m
The function in this graph is constant in the range of -4 ≤x≤-2 , Option B is the correct answer.
<h3>What is a function ?</h3>
A function is a mathematical statement which identifies relation between independent and dependent variable.
A graph is given
The graph will be considered constant when the y value is constant for any value of x
The value of y is constant in the range of
-4 ≤x≤-2
Therefore Option B is the correct answer.

Answer:
the 2nd one
a < -2 and a > 8
Step-by-step explanation:
for the first set of numbers it has >
and the second half it has <
hope it helps ^^
- 8 ( x + 2 ) + 5x = - 4
Start by distributing.....
- 8 x - 16 + 5x = - 4
Combine like terms.....
- 3 x - 16 = - 4
Add 16 to both sides.....
- 3x = 12
Divide both sides by -3 to get x by its self.....
x = - 4 is the answer
