Trigonometry allows finding the result for the decomposition of the displacement vector is:
x = 2.12 mi
y = -2.12 mi
Displacement is a vector quantity, which has modulus and direction.
The cardinal points are a reference system with respect to which measurements are made, this system is related to the Cartesian system with the East in the positive direction of the x-axis and the North with the positive direction of the y-axis.
In the attached we can see a diagram of the vector and its components, the indicated direction of 45 S of the E, in the Cartesian system where the angles are measured from the positive side of the x-axis in a counterclockwise direction is:
θ = 360 - 45
θ = 315º
Let's use trigonometry to decompose the vector d = 3 mi
cos 315 = 
sin 315 = 
x = d cos 315
y = d sin 315
Let's calculate
x = 3 cos 315
y = 3 sin 315
x = 2.12 mi
y = -2.12 mi
The negative sign indicates that the displacement is towards the negative side, that is, towards the South.
In conclusion using trigonometry we can find the result for the decomposition of the displacement vector are:
x = 2.12 mi
y = -2.12 mi

Answer:
After watching a show about submarines, Jamil wants to learn more about the oceans. The question that could be answered through scientific investigation is What substances dissolve in ocean water?
<u>Explanation:</u>
Jamil's scientific investigation will help him learn about the various substances that can be dissolved in seawater. There is a large number of such substances. Salt is the most important component of seawater.
Sodium chloride is the most common substance. Besides it, magnesium chloride and calcium chloride are also dissolved in seawater. Seawater consists of a large number of gases also such as oxygen, nitrogen, carbon dioxide, etc.
Albert Einstein published the theory of special relativity in 1905, and general relativity in 1916.
Answer
For conductors in series 1/2+1/3+1/6=1
And in parallel 2+3+6= 11
For the combination of series and parallel you get 2+11=13

Explanation:
There is a a little change in the rate of substantiated child maltreatment in the past several years.
In 2017 it is remarkably lower than 1990.
It has been decrease to 9 per 1000 children from 13 to 1000.
Since 2000 the rate of physical, psychological, sexual or emotional abuse have decreased .
The maltreatment rates are higher in younger children than older age children.
In maltreatment rate, children of ages 16 to 17 are lower than the children ages 0 to 3.
The rate of maltreatment of smaller children is 3 times higher than bigger ones
