How do you add vectors? Add the vector 3,4 to the vector that goes 7 units at an angle of 2π/3.
Gekata [30.6K]

The sum of two vectors is (- 0.5, 10.1)

<u>Explanation: </u>

To add two vectors, add the corresponding components.

Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.

Then, the sum of u and v is the vector

u +v =⟨u1+v1, u2+v2⟩

(b)

Two vectors = ( 3, 4 )

angle 2π/3 = 120°

In x axis, the vector is = 7 cos 120°

                           = 7 X -\frac{1}{2} \\\\= -3.5

In y axis, the vector is = 7 sin 120°

                                  = 7 X 0.866

                                  = 6.062

The second vectors are ( -3.5, 6.062)

Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]

                              = (- 0.5, 10.1)

How do I solve this I don't understand?
kykrilka [37]

Answer:

The equation for this sequence will be 8 + 17n - 17 with n being replaced with the term number you are trying to find.

so 8 + 17(16) - 17

17 x 16= 272

8 + 272= 280

280- 17= 263

Thus, the 16th term will be 263.
