They have the same slope so its inconsistent
Answer:
- 5
Step-by-step explanation:
The opposite of 7c is - 7c, thus the sum is
7c - 5 + (- 7c)
= 7c - 5 - 7c ← collect like terms
= - 5
I would say c because they both are the same thing just on different sides/ rotated <span />
Answer:
Magnitude: 3√10
Direction angle: 71.56°
Step-by-step explanation:
The magnitude ||v|| of a vector <a,b>, would be:





The vector's reference angle would be:





If
is your reference angle, then your direction angle ∅ depends on what quadrant the vector is located in. Since <3,9> is located in Quadrant I, then ∅=
, which means your direction angle is also 71.56°
