Answer:
a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.
b. ∅ = 
(Rx/Ry)
Step-by-step explanation:
Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.
The direction of the angle is found as
tan∅ = Rx/Ry
∅ = (Rx/Ry)
Ok like what kind of math problems
D because say you got 2 boxes of pens, 20p would be 20(2)=40 you would have 40 pens.
Answer: 54.4
Step-by-step explanation:
Using proportions, it is found that the least number of teams that will include all of the students is of 10.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 12 + 36 + 9 = 57 students will be divided into teams of no more than 6 students, hence:
57/6 = 9.5.
Rounding up, the least number of teams that will include all of the students is of 10.
