The total displacement east is: <span>
<span>15 cos(45) + 15
= 25.607 m
The total displacement north is:
15 sin(45)
= 10.607 m
The magnitude of the total displacement is:
sqrt(25.607^2 + 10.607^2)
<span>= 27.717 m = 27.7 m</span>
Its direction is N x E where:
tan(x) = 25.607 / 10.607
<span>x = 67.5 deg
The return displacement is therefore of the same magnitude
but in the opposite direction.
<span>Displacement 27.7 m, direction S 67.5 deg W</span></span></span></span>
Answer:
3/4
Step-by-step explanation:
x = <u>∛27</u>
∛64
x = 3/4
<em>Exterior angle of the triangle is equal to the sum of the opposite angles.</em>
9x = 5x + 9 + x
<em>Combine like terms:</em>
9x = 6x + 9
<em>Take away 6x from both sides:</em>
3x = 9
<em>Divide by 3 on both sides:</em>
x = 3
Answer: x = 3
Answer:
0.07525 kilometers
Step-by-step explanation:
1 millimeter = 1 / 1000 meters
250 millimeters
= 250 / 1000
= 0.25 meters
75 meters 250 millimeters
= 75 + 0.25
= 75.25 meters
1 meter = 1 / 1000 kilometers
75.25 meters
= 75.25 / 1000
= 0.07525 kilometers
