Answer:

-17

X lies between -17 and 10

(-17,10)

Step-by-step explanation:

|2x+7|

Solve the above inequality for x

To solve absolute inequality we take positive and negative

If |u|0 then -a

|2x+7|

-27

Now make x alone in the middle of the inequality

Subtract 7 on all the sides

-34

Now divide all the sides by 2

-17

X lies between -17 and 10

(-17,10)

Find the angle 0 between the vectors. u=(1, 1, 1, 0), v = (4, 4, 4, 4).
Naya [18.7K]

Answer:

30 degrees

Step-by-step explanation:

u dot v=1*4+1*4+1*4+0*4=4+4+4+0=12

|u|=sqrt(1^2+1^2+1^2+0^2)=sqrt(3)

|v|=sqrt(4^2+4^2+4^2+4^2)=sqrt(4*4^2)=2*4=8

cos(theta)=u dot v/(|u||v|)

cos(theta)=12/(sqrt(3)*8)

cos(theta)=3/(sqrt(3)*2)

cos(theta)=sqrt(3)/2

theta=30 degrees
