Formula to convert degrees in radians 7 vice versa
(Degree)/180° = Radian/π
Degree/180° = (19π/4)/π. Note that (19π/4)/π = (19π/4)÷π =(19π/4)x(1/<span>π)
= 19/4 = 4.75</span>
Degree/180°= 4.75/π
Cross multiplication: Degree x π = 4.75x180° and Degree = (4.75x180)/π
= 272°15 (π = 3.1459)
Answer:
the picture is super blurry can u change the picture and I'll do my best to answer it :)
Step-by-step explanation:
The magnitude of each vector is the Pythagorean sum of its components.
a. |v1| = √(2² + (-6)²) = √40 = 2√10
|v2| = √((-4)² + 7²) = √65
b. To make each vector into a unit vector, divide each component by the vector's magnitude.
u1 = v1/|v1| = (2/(2√10), -6/(2√10))
u1 = (√10/10, -3√10/10)
u2 = v2/|v2| = (-4/√65, 7/√65)
u2 = (-4√65/65, 7√65/65)
Answer:
(a×b)×c = 0 means that vector c parallel to vector (a×b). But because (a × b) ⊥ a and (a -b) ⊥ b so
c ⊥ a and c ⊥ b.
Hope this helps, have a nice day! :D
I believe the answer is -1
