8.333333 reoccurring. 1 divided into 6 is 1.666667. Multiply by the remaining amount, 5? Idk
-8, -19, -30, -49 , -60
<u>Step-by-step explanation:</u>
Here we have the following sequence :
-8, -19, -30, _ , _
- First term of sequence is -8 .
- Second term of sequence is -19 :

- Third term of sequence is -30 :

- Fourth term of sequence is :

- Fifth term of sequence is :
Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e.
and common difference
having general equation as :
.
We need to find dot products of 2 vectors:
u·v = x1*x2 + y1*y2
u·v = 2*(-6) + 3*4 = -12 + 12 = 0
Another way to write dot product u·v = |u|*|v|*cos α.
Because the do product = 0, we can write
|u|*|v|*cos α = 0.
That means cos α = 0, and thus α=90⁰, so vectors v and u are orthogonal.
