Answer:
Explanation:
As B has a y component of -5, A must have a y component of 5 to have the result lie on the x axis.
As B has an x component of 3 and the result has an x component of -4, A must have an x component of -7
A = (-7, 5)
magnitude A = √(7² + 5²) = √74 ≈ 8.60
θ = arctan(y/x) = arctan(5/-7) ≈ 144.46° CCW from the positive x axis

Answer:
r is the separation between the two spherical bodies
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. Stars are typically classified by their spectrum in what is known as the Morgan-Keenan or MK system.
First let’s pick one at random
Less than 5 percentile
That means they lined 100 kids up and less than 5% of them are that certain weight.
So if you apply this to every option you will see the answer is
A). Less than 5 percentile
