Hello :
v . w = <span>| | v | | × </span><span>| | w | | cos(</span><span>θ) ....(1)
v(2,0,1) w(0,1,-3)
</span>v . w = (2)(0)+(0)(1)+(1)(-3) = - 3
| | v | | = √((2)²+(0)²+(1)²) = <span>√5
</span>| | w | = √((0)²+(1)²+(-3)²) = √10
by (1) :
cos(θ) = (v . w ) / | | v | | × | | w | |
cos(θ) = = - 3/√50
θ =..... calculate by 2ind function ( calculator)
Answer:
x=6
Step-by-step explanation:
4x-1=2x+11
4x-2x-1=11
2x-1=11
2x=11+1
2x=12
x=12/2
x=6
18-->1
?----->10.6
18*10.6= 190.8 feet
(k + k)(4) =
5x - 6 + 5x - 6 = 10x - 12 =
10(4) - 12 = 40 - 12 = 28
The answer is 28
It is 24+6b im writing more because it says to put more cause my answer is to "short"
