Answer:
D. 7.8°
Step-by-step explanation:
There are many ways to work this problem. One is to subtract the angle of V from that of W:
∠V = arctan(2/-5) ≈ 158.20°
∠W = arctan(2/-8) ≈ 165.96°
Then ∠W -∠V = 165.96° -158.20° = 7.76° ≈ 7.8°
___
Another is to divide W by V, since the quotient will have an angle that is the difference of their two angles.
(-8i +2j)/(-5i +2j) = (1/29)(44i +6j)
Then the angle of that is ...
arctan(6/44) ≈ 7.8°
___
You can also divide the dot product by the product of the two magnitudes to find the cosine of the angle between the vectors.
(V•W)/(|V|·|W|) = 44/√(68·29) = cos(x)
x = arccos(0.990830168...) ≈ 7.8°
___
A plot on graph paper will let you measure the angle with a protractor. You can obtain sufficient accuracy to choose between the offered answers.
___
Your graphing calculator may have complex number functions that let you work directly with the angles of the vectors. (See second attachment. The calculator is in degrees mode.) Doing 2-dimensional vector calculations on a calculator may best be accomplished by treating them as complex numbers.

Answer:
when shared rules of conduct emerge and the team feels a sense of leadership
Explanation:
There are five stages of team development which are forming, storming, norming, performing and adjourning. A team starts from the forming stage, goes through the storming stage followed by the norming stage, and then the performing stage before the final stage which is the adjourning stage. Teams move through these stages, beginning from when they are formed and ending when they are disbanded.
When people start to understand their team members strengths with everyone is given a role based on their strengths and work as a cohesive unit, this is the norming stage. The correct option is therefore when shared rules of conduct emerge and the team feels a sense of leadership.
Answer: 2
Step-by-step explanation:
Because 1 is a number which represents a singular object adding another one gives you the value of 2
